HEEEELP! Basket case quad, Carb issues,.. :(
OK so I picked up one of these for my Wife to use as a pit bike for our 4 wheeling competitions, She needs it to move stuff for our fund raising,.. anyhow to the long and the short of it. $75.00 purchase price,..
Here it is,..
Got this unit as a "basket case" bike and I needed to tinker, the engine is marked 124.9cc and other than that I don't see any other types of identification on it yet,.. but to be honest I haven't looked that hard either.
OK so I started tinkering with it and first off found a toasty voltage regulator, broken wire harness, destroyed shut down system,.. ect , ect . Sooooo I got all those shenanigans fixed up and low and behold the little bugger we have nicknamed "wiggam" fired up! Now where it gets tricky, the carb has a hose off the bottom that has a steady drip of fuel coming out,.. OK I figure stuck float. Also when it did fire I could not adjust the idle at all, in or it the little bugger revved! So I pulled the carb apart and cleaned it out, washed it all with carb cleaner and figured that would cure it. So I reinstall it and whammo it fired and idled nicely but now I have a steady flow of fuel coming out of the overflow on the bottom,... Insert the all too familiar FML, SOAB, or other profanity,.. so now I stink of fresh high octaneand still stuck with a fuel problem,..
Did I hook the fuel delivery line to the wrong inlet?? Can I unstall the float back wards? Is there a carb breakdown for the unit about?? and BTW what is it?? Manf? Coolster? What kind of carb? Oh please help me here my brain hurts from thinking or I am high off the fumes?
Also if my ear serves me right I think a valve adj is in order,... How? BTW it has some nice fresh oil in it and a shiney new plug

Do you know the Make or vendor of the ATV? My friend bought a Chinese ATV for his kid and the carb was acting up, he called them and they told him they sell a optional better quality Mikuni carb for $50. They sent it down right away.
Well worth it.
Even if you bought a china new carb,it could not cost more then $20.

Well I checked the carb slider and it's got a key way to make sure it can only go in one way, still had a high idle so I restricted airflow through the carb and used a un lit propane torch to check for intake leaks. The gaskett between the intake and carb was leaking so a bit of black etc and a few moments cured the issue and I was able to set the carb. I rebuilt the lower arms with the welder and some grade 8 washers. Finally got the little bugger out last night and had a blast causing havoc in the alley, that little guy stomps especially once I adjusted the throttle from the kiddie parameters to the big kids option.

If you have a leak on an intake regardless of motor type you can use propane and the leak will suck in the propane gas and the engines RPM's will rise, if you want to test the idea take a unlit torch put it by the air filter turn the gas on and listen to the rpm's rise.
