I own and operate a small engine repair business and found you through your generator troubleshooting tips. Despite my vast knowledge of everything Small Engine there's always room to improve and I appreciate all of your generator repair tips and videos. That being said, this is why I generally turn down Chinese related repairs. Almost every single time something else is broken or corroded or not available.
Dude your patience through this process is like Buddha. This was extremely informative for me as I'm in a very similar boat but don't know anything about engines. Thank you for your time and putting this together
I love it when you have the young man help. I loved to work with my dad. Hands on will teach him more in life. My dad let me make little mistakes then show me the right way and that was good for me.
That young fella has a vested interest in that machine. I fondly remember the first and following Honda 50cc sport, Honda 65cc Sport and Honda Cub 50cc my dad brought home over my young adolescent years. All had something wrong with them. The first had a Stripped out and welded on kick starter lever and problems within the transmission that dad and I repaired and rebuilt, the second also had the same problems came from the same coworker was ridden by his younguns. The third had only a loose connection between the two halves of the carburator which recurred again until dad decided we would stake the screw heads and aluminum body to prevent their loosening and that worked for years. I had never heard of loctite back then in the mid to late 60’s. By the time the second bike rolled in dad had a major window and siding replacement project going on at the house and basically said you know where the tools are. One of the worst problems encountered were how tight the factory installed and different material of steel bolts and aluminum vase resulted in the Phillips (can’t recall if equivalent to a #2 or #3 Phillips head were tightened. Had luck with using a hammer and good Phillips or a piece of brass to impact on the screw heads before removing but some heads were already stripped out by someone else’s efforts so a cutting chisel, penetrating oil and patience was the cure for them and buying new screws from the local Honda dealer, the internet wasn’t around yet either. I rebuilt the trans on the 65 Sport, replaced the seals, rings, cleaned the cylinder with abrasives to help new rings seat and resurfaced the valves like you do. Lots of fun times with my dad overseeing, or just checking in on my progress from time to time and after he stopped his window replacement work for the day we might go fishing anc he would ask me what I had done and if I did not mention a key step in doing something he would say are you forgetting telling me about something else you did or are you gonna have to tear back into that area to do that step. We didn’t have any pneumatic tools or even a manual hammer blow impact though we sure should have bought one but dad was use ti doing things without all the right tools. We lived near acres of woods and where high voltage high line and highway right of ways were being carved out if the woods so we always had somewhere to ride off-road not that it kept me off the roads as the tickets I soon accrued would testify to. Hope is in in for a world of safe driving, our bikes were never really powerful enough for the stunts you see youngsters doing now in motorcycles do jumping creeks and such and seeing who was the fastest through a course we made was our injury provider. Lots of fun. If that bike is a true 50cc and geared right as light as it looks it should easily go 55-60 mph, even our Honda 50’d would do that on a king straight of way especially with a bit of downhill. 45-50, even 55 was usually no problem on flat terrain with just one rider. Watch out over him you may need to add a throttle or rev limiter depending on his own developing riding style. We also had no riding gloves, pads or helmets which I would suggest a helmet at least but that is your and his choice, kids, at least I did tend to feel invincible even though we weren’t
The reason the compression is so "low" is because with a very small displacement engine, the short and small puffs of air get absorbed in the gauge hose and don't make it into the gauge. You will need a hose with the Schrader valve as close to the spark plug hole as possible to get an accurate reading (and it will take more pulls to reach the maximum gauge reading compared to a larger engine). Love your videos keep them coming!
That is a strange looking float configuration with the float NOT attached to the hinged plate actuating the needle valve, guess that’s why it’s a full circular float. Definitely new to me.
The rubber disc in the fuel tap either swells up, blocking the fuel or crumbles, blocking the fuel, depending on what brand of old sneaker sole they cut the rubber washer from.
When you puller once you got it some pressure on it hit it with a hammer and it will usually pop off if you just keep turning you can crush the end of the crank shafts. Another trick you can do to make a gasket it to hold the gasket material on the partt and use a Ball pain hammer and tap the edges till you cut the gasket out look it up Roadking85 dose all his homemade gaskets this way saves one step Love the videos you do keep them coming
Piston is scored more than you may think. Not having gaskets on carburetor, loose cylinder head, and loose/misaligned reed valves leaned it out. Doesn't take long on a 2-stroke. Another seller that lied like a rug. On cheap Chinese bikes and acts, anticipate more problems than normal until you get it sorted out.
Those things dont have brands, they're the most generic junk china makes. Steer clear is the best advice I can give after racing those motors and working on them in a pocketbike club.
Should have walked away- it's worthless when new. Why order new parts when the scrapyards are piled high with those things. Better to pick a lifan 4 stroke pit bike from the scrapyard- they're also plentiful because nobody wants them. We once had a club, racing the road style pocketbikes, had all the go fast stuff- hi comp barrel+ head kit, fibreglass reed valve, advance timing key etc. Would propel my 140kg bulk to 60kmh, but wears out quick! Those carbys are the shitty ones- use the diaphragm carby instead that some of the sportbike models have. The built in fuel tap is the worst part!

So good to see your dad working with a son like this. You’re a good teacher, dad

I know someone in the Condon house is happy !!!!
Good video liked seeing the next generation helping out
Very good it makes my heart glad to see the future rider help
The reason the compression is so "low" is because with a very small displacement engine, the short and small puffs of air get absorbed in the gauge hose and don't make it into the gauge.

Love your videos keep them coming!
Thanks, was wondering about that. Have test a few other small engines that ran fine, but same result.
Yes,comression testers for cars with long hose,Illike the one ,it has a rubber cone ,fits over spark plug hole
That is a strange looking float configuration with the float NOT attached to the hinged plate actuating the needle valve, guess that’s why it’s a full circular float. Definitely new to me.
Lol right after I come to you mention having a new engen already lol
Very interesting. Thanks.
Thank you
The rubber disc in the fuel tap either swells up, blocking the fuel or crumbles, blocking the fuel, depending on what brand of old sneaker sole they cut the rubber washer from.
Big bore kits are like 60$ or about 100$ for a new big bore engen
You need to buy a set of T-handle Allen wrenches if you haven’t already. They are invaluable!
my mac t handles are a god send
Sweat equity in this for that young man it's easier to learn if you got your interest in mind LOL

Just need a fuel cap
$4 million
Said the seller
😂
it's the idle screw not the air screw.

I hope you didn't pay too much. I hate when I get ripped off sorry it happened o a nice guy like you
I did not pay that much, but it cost a lot in the end.
To buy one new is ripping yourself off. The lifan powered 4 stroke bikes and quads are the bare minimum to own.
If you want to start this engine put some gasoline and oil down the cylinder through the Spark plug hole
what bike is this(the brand and model)?
Those things dont have brands, they're the most generic junk china makes. Steer clear is the best advice I can give after racing those motors and working on them in a pocketbike club.
Please send my Type of spark plug
Bro that thing has half a frame.

Should teach your kid on your own time
