Ok so, this is my 1st ground up build( Building rear Rack, using parts of a Kit...Motor/gear reduction/throttle kill switch, building mainly with some scraps/mechanisms I picked up for free, minimal hardware from Lowes)& I have very limited space but it's coming along nicely. Rack is done other than thread locker & notching the piece of 1/8th U aluminum 1-1/2 X 1 inch to mount the chain tensioner I made(pics later). The rack itself is some weird teflon coated 1/4" L shaped aluminum I cut in half then joined to make a U shaped rack. The U shaped brace legs are really ridged I got it from an old A/C ductwork square I broke down. Using this Fat tire bike & having a chain for 26in bike I'm taking the gear box & flipping it downward already checked my height after tensioner it's dead nuts where I wanted it.
My 49cc 4 stroke has been sitting for at least a year I'd say.
I got this motor/kit used on Craigslist for $80.
Changed the oil
I went through the carb to the point I could taste the carb cleaner it really wasn't that dirty to begin with. The air filter has good foam but the previous owner cut the air box I think to fit it on a mid frame mount.
Went to start it today & nothing...
Removed foam air filter(which has a light layer of oil) tried again & no go.
Pulled the spark plug & it had a lot of oil on it it's a torch plug gap was small went to .028 .032 nothing. Pulled the choke halfway same with the throttle & shot some carb cleaner up there & then pulled the cord & it turned over, ran for maybe 8 seconds, then died.
Couldn't get it to turn over again until I repeated the carb cleaner it turned over for 3 seconds & died. Fuel lines(gas supply line has inline filter) are good.
What is most likely wrong?
What can I do to clean/tweak/fix this to where it's next to new and dependable? I know it turning over is a good sign I want this to be a dependable daily rider
