reviving the dead 150cc

[dazeinhaze]

Ok so I got this scooter that didn't run wot 2100 miles on it. Owner says it was stolen n leaked all the oil out. So I assume it was ran wit no oil as the oil screen screw wasn't even finger tight(duh) . So I went ahead n bought a big bore kit cuz the the old piston n cylinder where very much scraped n worn badly. I replaced it and now it seems to wanna start so I spray some gas in the Carb n it starts brielfly n dies immediatly like there is no fuel supply. Any thoughts

Did you clean the carburetor jets and replace the old gas.

GO FOX!

Also, there is a "L" turn from the carb gas intake to the float needle, this is in the metal body of the carb just beyound where the gas supply attaches,,, this turn can get a ball of god knows what in it and feed the bowl too slowly, this turn is one of the hardest parts to clean out on a carb, mine got a piece of metal stuck in it.

you could spray carb cleaner rite by it, but in till it flew out of the needle hole out across the sun light glinting, my bike ran like crap.

which took 4 cleanings

always assume you have more then one problem when the bike is opened up, find something wrong don't stop there, still cover everything.

my second problem was not only was the gas bowl not filling, --

BUT MY CDI WAS WORN OUT.

CDI CAPACITORS WEAR OUT


so after blowing that metal speck out of carb supply turn.... it ran much better, and stopped dying out at half throttle

but the new CDI put the BIG peppy back in my bike.

some CDIs are dirrect current,,, MOST are alternating current,

make sure you buy the right kind, if your head light does not come on till engine turns ON you are most likely a AC fired cdi.
