I'm not sure where to even start, or where to go from here.
My oldest son aquired a 50cc Jonway last year, a non running beat up POS.
Anyway, he wanted me to get it running for his birthday.
The rectifier visibly Burt, I had to re wire in a new rectifier. The petcock was junk, I replaced it, with new fuel line, and filter.
The carb was very gummed up with slime. I installed a new carb.
It started, but it didn't start easy. Then after running for 3 minutes it would kill, and not restart. I checked and there was no spark.
I changed the plug, coil, and cdi.
Then it would start hard, and again run 3 to 5 minutes, kill and could not be restarted.
Again no spark! So I changed the stator yesterday. It started and seemed like I was getting closer, until it got warmed up, then it won't restart again! But this time, it has spark, and fuel... So, I'm thinking valve adjustment. I found my tdc, and adjusted the valve lash to .004. But I noticed some slop in the timing chain...anyway I put it back together started it, and all seemed great...until this morning....it won't start at all! It has spark, it has fuel.
I'm thinking the timing skipped a tooth!
If not, I have no idea what's going on with it!
All this time, and money in this pile, and I feel like iv'e completely failed!
I kind of lost it, kicked it over, and beat it down with my hammer, so now I need some new plastics.
I gave my son my Lance 50, but man I need a good gas mileage town cruiser.
Should I even bother doing a motor swap?
Patience, is not my strong suit...but I am compitent enough to do it. And, I just don't have the funds to buy another scooter, but a $350 gy6 I can do.
