Well,well, well... Another very interesting and informative video. I know that I do have one of those aluminum magnets. I just need to find it! They do work slicker than snot on a chicken's lip! Thanks Mark! 🫵
@bigmoustacheal3295 Being on the farm, I usually have a supply of those magnets under my fingernails for safe keeping 😉 Don't let the feline out of the burlap, but they also work on magnesium, titanium, and off of those other make-believe metals!!
I just knew you were going for that aluminum magnet. I always wanted one for brass casings. I'll have to remember the grease trick. I always learn something from your videos. Wish i could remember half of it.
@Kevin.L_ For brass casings, there's one more step: after you're done and while your wife is at work or otherwise occupied, you need to throw them in an old pillow case and give 'em a cycle in the washing machine to get all the grease out. ...that or give the casings 0.002" more neck tension and a crip. Heck, we both probably learn more down here than we do in the videos!! 😉
Instead of relying on the H needle to flow all the fuel you can also add a non metered fuel passage within the nozzle. It will need to be very small as there is no needle partially blocking the orifice.
@srcarr52 Oh my goodness!! That makes perfect sense; I never considered it, but it's so obvious now that you mention it!! Thanks so much for the kernel of wisdom!!
@ your mod is great and it works well when you need only a touch more fuel. Some larger carbs already come with the 2 high speed passages so the H needle is only metering a fraction of the fuel. Either way you mod the H side you’d still need to mod the needle and seat to keep the bowl area from going dry and leaning out on long cuts. You did a great job of explaining it all!
@HawtSawz86 Thank you!!

I learnt something today! Thanks for the video. I’ve been having a similar problem with my 024 I put an 026 top end on, it’s a really strong saw but it starves for fuel in bigger wood. I think you may have solved my troubles today.
If it's a 024 AV SUPER, it'd have the same crankshaft as the 026. If it's the 024 AV, it won't. Did you make sure the piston comes up to the combustion chamber?
I have no idea it’s one I found in a dumpster, but I had to do a ton of machine work to get it all to fit. The top of the piston was way too short at bdc it was 120 thou below the exhaust floor, I milled the base of the cylinder at an angle so the pot leans back towards the carb to give an offset and avoid free porting under the piston to the exhaust. Once I got the top of the piston level with the exhaust floor I had to machine a top hat out of the piston to get some squish. It ended up with short exhaust and long blowdown. It doesn’t like the 024 carb it’s better with one from a 026. It cuts really well but leans out in big wood, it’s on a 16” bar and when that bars fully sunk it can’t get enough fuel. I was thinking about putting a larger carb on it but didn’t want to go for a bigger throat. So far it’s all parts that were either thrown out or left over, the only thing I spent out on is a fresh set of rings ( I did fit both) and some gasket goo. I got nothing to loose trying the carb mod in this video!
@jaysparrowhawk9388 I sure hope it can help you. Suitable carbs suitable for a swap (without modding the carcass of the saw) are very few and far between on these saws.
@jaysparrowhawk9388 Sounds like you fell into a pretty sweet deal with the 024!! Making something out of nothing is an awful good and rare quality in today's world!!
@SepticWhelk I *think* the different colors/types of diaphragms are actually designated for different fuel types such as Ethanol, non ethanol, etc... I may be wrong, but it's what I understand to be the case.
Just curious, what numbers do you have on the 026. I am starting to port one. Just wanted to know what they were for reference. Also good to know how to get more fuel into them.
@TheJohnDeereGuy Sure is a good deal on the carb!! The numbers on my 026 were (I've detuned it a little since then, so that dad can start it easier) 99 Exhaust, 124 Transfers, 143 total intake, squish was .018. Bear in mind that all numbers were taken with .035" mig wire and NOT first ray of light!! I like the numbers; they made good power and it had nice manners!!
@TheJohnDeereGuy The timing numbers are approximate in that I had also move the cyl 0.060" and the BTDC and ATDC numbers are different by ~1 degree. I made the biggest porting gains with big lower transfers shaped to direct the charge toward the intake and upper transfers aimed a little more upward and also a little more toward the intake. I think I showed them in previous videos; if I didn't show them well enough, email me (email is always in the description of each video) and I will take some more pictures of ruined cylinders for you.
Excellent!!

@camrynrhodes798 You're quite welcome!!
Wow, thats some interesting stuff, thank you Sir.
@mattw5729 Thanks!! It's good info to make a ported saw work *OR* to help those aftermarket carbs chooch like they're supposed to. Thanks!
👍
Hitch hiker it is. Thanks
@itllkeal Thanks for riding along and keeping me company!!

@srcarr52 The help and also the kind words mean a lot!! Thank you for that!!
Fantastic video my friend
Question for ya, do you have a favorite jet drill set?
🍻

Them pale brown fiber pump diaphragms are supposed to pump more fuel ?

@HayChaffandSawdust1 Thanks that's about where I am at with this one. Can't wait to see what it can do.
