Jimmy Diresta here, / jimmydiresta l got this broken gas drill last year from youtuber hand tool rescue asking if l could get it to run, well we kinda got it but was still having problems, since then another youtuber sent a mini gen set that has the same engine, lets see what is wrong by taking the both of them apart to see what was wrong on the drill.
I have a '78 Honda Goldwing with a mechanical fuel pump that developed a crack in the rubber diaphragm (which is very similar to this diaphragm). Since all the check valves are on the wet side of the pump, I cut a new nitrile diaphragm and placed it on top of the old diaphragm (on the wet side). I used a new Nitrile glove (one of the blue ones) and used the palm area since that was just big enough without any stretching needed.
Works as it should now and it was one of those moments where I amazed myself. A very simple fix and even ten years later, no further problems.
Love that lil generator........drill also cool but that generator is pure history. Thanks for the guy who sent it to you :)
I feel mustie deserves the generator more than myself. After all his commitment to the community, and assist the repair of the drill, least I can do is provide a special gift.
It will basically sit on my garage pedestal, and nothing disturbs me more than an engine that works.....doesn't gets their exercise or serve their purpose.
Mustie will provide a better life for it and will bring in joy.........as long as it runs at least lol.
Thank you for finally getting this insane thing going! If we are ever all in the same room, we should probably ceremoniously burn this drill.
Even burnt Mustie would make it run again. ;)
Are you going to finish it?
I say we run over it with a forklift Mustie gets running!
Hand tool rescue or save the engine for a modeler to put back onto an old airplane. These things are just too cool to destroy maybe even in drill form if you feel that way lol
thanks again for sending it my way, l enjoyed the challenge
Hey Mustie1, here's a method for cutting the holes in thin material like: Find a piece of brass or copper tube that is close the the same size as the screw or hole and use a rotory-tool cone style grinding bit to sharpen the inside of one end of the tube then use the tube as a hole punch.
First of all, you are very welcome to show the story behind this generator :).
I'm so happy to see her on the spotlight. It was revving high since I set it that way, might be too high lol sowwie.
And the fuel mix was definitely lean since it was last set last summer here in Florida lol, again sowwie.
But I'm surprised it gave alot of pulls to start but I'm very happy to hear her properly.
EDIT* Now I see why, that diaphragm was terrible. I received it as is, the carb pieces are all original from my prior ownership. I just clean it and it ran so I left it alone.*
Awesome video as usual, enjoy your newly acquired piece of history. I made sure at least the spark was there, I cleaned/adjusted the points as per spec on the pullstart cover. And it did ran prior shipping but....again Florida setting lol.
PS: 40:1 is very, very lean. They LOVE and NEED oil. 25:1 is good. If you dont see oil out the exhaust, it is not enough lol.
EDIT #2: @Mustie1, I totally forgot one special info. I forgot to send you a set of leads to the alligator clips. You see those two wingnuts at the end of the generator ?
That is for 12volts. It charges car batteries :) I have not tested that feature so put a meter on it prior.
Great job!!! :D
Alex
thank you again alex that was very nice of you and it made for great video.
@@mustie1 you are very welcome sir, keep on wrenching!
That is a cool little unit.
alexboi32 Yes, Thank you again for sending it to Mustie1. It was a great help to troubleshoot the drill engine! Very nice of you!
If you send it - It will run.
Way to go Mustie! Amazing patience and perseverance. Thank you for sharing.
Mustie...I have to say I really like your videos. I also want to tell you that if it was not for you I would have not been able to repair my snowblower. Your videos about how to work on the carb saved me a bunch of money!! Thanks for all the effort you put into your videos and how much fun they are to watch!! Keep up the great work!
thanks jaxon
Mustie1 gives us the best Sunday entertainment, thank you for letting us be with you in your garage.
You are an awesome fixer. I’ve learned so much from watching your lawnmower and snowblower videos. I only wish I have the opportunity in my garage to fix equipment like you do.
I was watching another channel and the guy said, “Like Mustie would say, ‘must be the carburetor.’”... Than I got your notice.... Made me smile....
So nice a mustie1 video, warm bread and coffee.
The perfect Sunday. Life is good.
Yup! Watched him for a bit with a coffee. Did some errands took a nap and now another hot coffee to finish it up! Go pats!
Thank you for turning a wrench today. After a double shift it’s nice to come home to a good video and learn a little bit.. 🔧.
Mini footnotes on the generator:
It produces 300 watts of power at full load, some say 350 but 300 is their sweet spot before damaging the generator.
It has a 12v hookup via wingnuts at the back. It creates up to 12amps according to the manual.
12v hookup and 120v plug can be used both simultaneously as long as it wont overload the system. DO NOT REVERSE THE POLARITY OF THE 12V CONNECTION OR DAMAGE WILL OCCUR!
The diodes will blow, and the generator will be compromised.
Adjusting the fuel mix and governor is to be set after the engine warms up and the specified load is applied. There will never be a set adjustment, only adjustment will be set by ear (running smoothly). Off load running will be high or choppy and stated it is normal. Dont touch it unless a different load is made.
There is no info on set RPM or Hertz since the adjustment is made by ear at their specified load of 250-300 watts. I'm sure it supposed to be 60hz, but judging the sound of engine, its definitely turning more than 3600rpm.
The carb fuel pump system utilizes a small port after the throttle butterfly. When it is closed, the pulses from the intake transfer through that internal port which goes through a series of chambers to the diaphragm. Then the check balls and the special check valve gasket does the one way fueling to the metering valve. Then it goes out to the hole before the butterfly.
This design is recreated on newer ryobi/ troybilt 4 cycle engines like their blower and trimmers. You'll notice their walbro carbs do NOT have a pulse hole like your generic carbs do to function the fuel pump. They get their pulse from the vaccuum of the intake after the butterfly ( or barrel on their walbro).
Only difference was on walbro 4 stroke, they have a spring on their diaphragm to push back after the absence of vaccuum.
Since this is a 2 stroke, ohlsson/rice carbs pulses with vac and blow so no spring was needed. It moves the diaphragm normally.....hence their compact and crude design.
They are inefficient on today's terms and definitely not EPA friendly but who cares, it is a badass rare little machine.
That's the cutest little gas-powered electric generator I've ever seen~!
Your organizational skills are only surpassed by your problem solving ability! Thanks!
Hi Mustie, If you find the material used for the gasket, get yourself a small laser cutter/engraver, this would allow you to cut your own complex gaskets. With regards rejuvenating the old gasket, try 303 Aerospace Protectant spray, soak it in that for a while, as it's designed for vinyls and rubber etc.
small engine will it run great start to a Sunday. thanks Sir HUGE THUMBS UP
Lol those aren't thumbs...there adjustable wrenches..😎 They we're obviously built to fix things
Back before cordless drills, these were what we used out in the field to inspect utility poles. Pain in the arse!
Brad O'Neal yes sir also in the past used by utility crews to mount hardware for hanging cables, cross arms etc.
Hi Mustie I. I enjoy all the different things you do with the engine’s and the car’s and the way you bring your audience into your space keep doing what makes you happy as I can see your enjoying your channel.
I do Pat 🇦🇺. 👍

Nice work fabricating the “new”gasket. Great video.
Seeing that gas drill brought back memories! Linemen use them to frame an inaccessible pole! I can tell you that gas drills are a mixed bag of emotions, sometimes. Ours never had the primer button, but they either want to work, or not at all! I kept a brace & bit handy, just in case!
Thanks for the memories!
Anyone else think he would make a great shop teacher?? I know I would send my kids to his school.
We are students of the University of Musti 1 at New Hampshire
Yes, I do. He missed his calling.
I agree this guy is awesome
I was literally thinking the exact same thing!
Would make a good shop teacher. Thumbs up mustie1
I have always used rubber gasket sheets to make my own diafram. Dont know about there in USA, but here in Norway we can get like A4 size sheets of rubber gasket material for 4-10$ for 2ps of A4 size sheets.
Thanks for another fantastic video.
never understood the first thing about motors but I keep watching and learning. Fascinating stuff . Thanks and ATB from Belgium - Marc
Saw fuel pump diaphragm material sold by the sheet on eBay. Thanks for the great videos mustie
My Dad worked for the local power company and they bought 3 of these which said “DRILLGINE” on them. They bought them for the linemen to use in bucket trucks. They never started so the guys did not use them. We wound up with one that was going to be scrapped. We got it working but you couldn’t depend on it. They thing was so small things were always going wrong with it. It was 2 cycle. I’d like to send you a picture of the go cart my dad built for me 52 years ago. Just needs cleanup and a throttle cable.
That's how hand power tools should be made - no faffing around for 16 hours while the battery charges up, or the battery dies four holes from the finish. Just fuel it up and you're away again in a minute! . . . Got to say, I do like that "Tiny Tiger" generator. I could just imagine that in the back of a pick-up, and spending a week in a mountain cabin, using it to power the lights, perhaps a radio, and finally, recharge the pick-up battery because we left the interior light on when we parked it!
We don't make things like we used to, that's for sure!
I’m liking the little generator, great fix on both.
I love watching the 1 hour vids. I learn so much about small engine repair and VW's. Never can get enough of Mustie
That generator is nice & quiet for Camping.
Or charging your car battery early in the morning when your car won't start xD
@@lulink99 lol neighbors
It isn't.
Edge of your seat entertainment for sure!! I was beginning to wonder though, but then I snapped out of it and remembered it was Mustie1! Well done sir!
I would like to thank you sir for having in depth videos on small engines and motors helped me fix and determine if worth fixing some of my stuff thumbs up and thanks again
I like the gray benchtop blanket. Nice touch.
As always....it's a pure pleasure watching you work and answering your questions throughout the video.
That tiny tiger is the cutest source of electrons ever.
I learned the hard way, the Mylar flap-valve membranes go on the embossed side of the assembly, and the gasket goes on the machined smooth side. I misread witness marks while reassembling a Husqvarna demo saw carb and ended up with a no-start and a fuel leak. I had to backtrack to the beginning and analyze every part as it went back together. Talk about a learning experience!
I have watched this drill travel the US. Now it works I want to see Diresta use it. Cheers
Get the raw diaphragm material from Mcmaster Carr and make a small run of carb kits for these carbs. Model airplane types would love you! Try the Silicone oil / spray to soften up the stiff old diaphragms. That was really good advice in those earlier comments!
Boy, those two tested ya . . . . great patience and perseverance . . . . :) Rog
Forget Superbowl Sunday it's mustie1 Sunday.
I think that the problems we are witnessing with these is the main reason why the concept never caught on. There seems to be a limitation with engines of this size that corresponds to reliability, ease of use and the trouble with locomotion. Ferrying fuel along with this and the quirky nature made running electric to a location to power a conventional drill a no brainer. I appreciate the challenge and the effort to get it to go, but if we really needed something like this to work and we spent this much time and got it going for a little while and then went home and came back the next day and were back to square one, I think most of us would say screw it and buy a mile worth of extension cords.
These are pretty cool little engines. Nice job Mustie!
Good job at troubleshooting all the issues on that little motor 👍 What a battle for such a tiny engine lol
Just ran across this channel looking at oil undercoating vids. I instantly recognized the VW truck! I've seen you around at a bunch of local car shows.
Cool channel!
Your perseverance is admirable.
Not even 22 minutes in and I’ve already caught you whispering to that second engine. That is the sign of a good handyman. Again another great video.
Thanks for letting me spend the afternoon in your shop. VWs model airplane engines and spilled gas on the bench, I'm a subscriber. Been watching for a while but today did it for me. Thanks
I may never work on small engines like these (Famous last words), but the trouble shooting techniques that you use are critical to working in any gas engine. Spark, fuel, carburetor, and compression. Simple timesaving steps, like using a separate magnet bowl for each carburetor and trying to make a gasket are second nature to you, but foreign to me. Thanks for posting. I always learn from your videos
P.S. the Karmann Ghia looks marvelous
Very cool little engines they look unique.
You have the patience of a saint. It's always a joy to watch you beat entropy with dogged perseverance.
Hey mustie, Iv'e been feasting on your videos for about a week now, And i'm thoroughly enjoying them, And iv'e learned a lot along the way, And i now have the confidence to check the float bowl in my lawnmower for the first time in 30 years lol. You certainly know your way round an engine, Keep up the good work, All the best from scotland.
Best channel EVER! Thanks for the great start to my day! I am so happy you revisited the drill.
Mustie, not sure if another one of the 486 commenters below mentioned this product for the rubber gasket. Rawn Re-Grip Rubber Cleaner & Revitalizer. Excellent product. Readily available on-line and not super expensive. A little bit goes a long way. Worth it for future projects, if you’re interested. Great work!
Yeah, as someone who watched the other videos on this drill very recently, you should have scrolled through them to refresh yourself. By the way, I remember on HTR's video, he has some documentation along with the drill that I guess he didn't send you. Might have shown a breakdown of that pump. Love your content. I've learned so much.
I have a little nemesis myself, sits on the shelf above my bench.... a cute little very lightweight leaf blower with a 24 cc engine, fully rebuilt carb but only runs if bottle fed. It's annoying as hell but I just can't throw it away, yet.
Screw the superbowl I'm watching this.. 👍
A much better use of your time :)
@@gregorythomas333 I agree 100%
It's the Super Floatbowl...
Outstanding. Two people (maybe more) couldn't get the drill going, but you did. :)
love the label on the Tool Box "More Down Low"
Love your videos. You have helped me fix and keep all of my yard tools and chainsaws running. Thanks. You are the best !
I love watching you work on this stuff. Most would just toss it because they don't have the paitence to even try to fix it. Obviously that's not an issue with you. I know you really enjoy figuring out what makes these things tick. My hat's off to you for making just about everything you tinker with run once again.
Well done sir ! Your perseverance paid off . I hate those little diaphragm thingy's !!
You have an extra measure of patience, which my wife says I don’t have any, I am jealous.
Mustie has more patience than I do by a wide margin. I am re-watching his videos and must say that I much prefer the ones shot in his home garage. Seeing his collection in the background is great. I know that he needs the space in the new garage and the better lighting, etc. but much of the character is lost. In any event, Mustie 1 is great. Thanks 😊.
LoLoL your old carb gasket with the qtip.... worked perfectly! LoL
The generator is the cutest little thing I've ever seen. I wonder if it's DC? Although it has a household plug on it, I wouldn't put it past outputting DC since that's all you need for incandescent lamps and tools with universal motors.
the bottom 2 wing nuts under the plug does have dc output,
Mustie 1 is a brilliant alchemist. I enjoy the videos immensely. Thanks a million.
Had a pushrod seize in me. Cleaned and polished it up well and lubed it with 3n1. Got points working again. Love your vids man!
That drill looks like something Tim the Tool Man Taylor would have made :) Great work Mustie! Was a pleasure hanging out w/ya.
Great job Mustie...I love how you get the old obscure stuff to work...
My son came up with one of those Tiny Tiger generators back when he was in high school. I don't think he ever got it running, something was broken. It is neat to see one running.
Life is good. It's a rainy sunday here in Georgia it's always sunny with mustie1
Actually I did think you had forgotten the generator. But you didn't. Persistence payed off. Great video.
Over an hour of Mustie?! Didn’t we just have Christmas?!!
I always use a couple drops of lighter fluid on a chunk of thin cardboard to run between the points after dressing them up to clean any residue or oil out of them... works great
Yet again, genius.. great vid mustie1. I thought i was the only one to go this far, i think you just topped me. Well done Brother.
Thanks for the sneak preview on Hand Tool Rescue. Yours and his are some of my favourite channels on UA-cam!
Brings back memories of a Cyclemaster Mustie - long ago. Standard was just under 1 BHP but being 17 and in an engineering apprentiship it got tweeked. I made a simple rope break dyno and got about 2.2 BHP at 10,000 RPM. The unit fitted inside the rear wheel of a bike. Standard was 300 MPG. Mine was a lot less MPGand broke 2 frames off under the saddle. It was quite normal for the flywheel to shear it's woodruff key and come off. In the winter, early morning and still dark a short cut to work took me along woodland footpaths. Later I had motorbikes that would do a ton but nothing scared the cr*p out of me like that Cyclemaster. Good days. Thanks for the memory.
Tenacity is an admirable quality. Well done.
It's a miracle these condensers still work. The condenser is just a metal bodied capacitor. At one time, capacitors were known as condensers and the moniker has stuck in engines. Presumably they are ceramic or something.
ah nothing like the repair and sound of vintage engines on a sunday on this very darn cold day.
Well done sir...well done. I got a little edgy when you began disassembly of the "good" carb. But you pulled it all together. BRAVO !!
First time I ever seen a primer, built like that. Great video mustie1 👍👍👍
Those "challenges" puts my patience to the limit. Nice job Mustie !
i really like your videos. i also work on small engines in my spare time. thought i would share a tip. try using pensil earaser for cleaning electrcal connections. works great and dont remove any metal
Have to mic the thickness, but McMaster carries Buna-N (oil resistant) rubber sheet as thin as 1/32" (0.031 inch).
I ordered some and it's not the same. You need fiber-reinforced Buna-N sheets. I finally found some on eBay!
Yeah, I've cut diaphragms and gaskets for similar carbs that generally work great. Tedious as hell. I used to have a gasket cutting/punching set but it got lost in a move. I was a Machinist Mate in the USN and we made a lot of our gaskets and diaphragms at sea (no parts store around the corner). A set of leather punches works pretty well, especially for small holes.
I love learning how to fix real problems from a real expert. Like an apprenticeship this is how people learned a trade before all these modern day schools. I spent a year learning about communications equipment but all I learned was how to tell when the equipment was working. My real training began when I was out in the field, at 2 in the morning, facing a real problem, costing the company three thousand an hour, under a time limit and with no one to help you. You find ways to get things working or you get out of the business.
...Grabbing that coil to start it.... Heh!
I'm glad it has no cracks or leakage, or you'd know it first pull!
Someone was really industrious with the idea of fitting a small aero-model engine on various implements, i see. Neat. I figured that the drill was a one-off deal (to be read, just that type of unit). I wonder what else has that running set on it if they did the generator.
My grandmother had a washing machine with an O&R engine!
Back in the 80’s as I was restoring a ‘64 GTO, I found that DCM, Dichloromethane, would bring rubber back to almost new look and pliability. The fact my dad was a chemist allowed easy access to the DCM. I wouldn’t know how to get it now. What a great way to spend a Sunday morning.
Ok, I just watched all 3 of your video's Mustie1......and also the one from Hand Tool Rescue......in my opinion HTR put the carb back together with the clear flapper check valve on the wrong side of the spacer and you inherited it that way......until you had a second donor unit which ran a small generator to make comparisons and came to the realization that the clear flapper check valve needed to be on the proper side of the spacer for the system to work.......excellent project, really enjoy your video's.....keep up the good work fine sir.
Glad to see you revisit the drill and get it working!! Also that gen is pretty cool, especially with the 12v output.
Nice work Mustie, great video.
That little gen is cool.
Determination!!! Excellent work!!!
You have more patience than most my friend
it helps to always take pics of things you take apart
then there is never any doubt of the sequence of the parts and how they go back together
Never saw a drill or generator like that before...it was a pleasure to watch you go through the thought processes so methodical, I thoroughly enjoy your Vids as I fettle things myself.
Was watching something else when I got notification of this. Had to click to see what the project was today. Nice work.
Nice work! Those O&R's go for a mint price on ebay so they are very collectable!
