Hi All,
I have a 2002 Bajaj Chetak 150cc 4 stroke I'm trying to get running again and I've run into a wall, seeking your insight. I got it for cheap from someone that said it's been sitting 5-6 months and it had started fine before it just sat.
Info I have collected so far:
OD reads 2200 miles
Spark:
-Compression is good at 170 psi
-valves are within spec (I had to adjust the exhaust valve, it was a bit too open)
-Verified spark by grounding spark plug to engine block and kickstarting, bright blue
-I replaced spark plug hood with NGK resister
-spark plug wire has good resistance (coils seem fine to me)
Air:
-Air filter and passages are clear
-I replaced o-rings at the cylinder intake and carb
Fuel:
-Filled tank with fresh gas
-I cleaned the carbs and reassembled (they were pretty clean when I opened them up)
-fuel flows freely
-float height is within spec
-throttle cable is loose, it's stretched out and can't be adjusted, so there's some slack in the throttle cable
Fresh battery fully charged.
Problem: The engine will turn over but despite all my efforts it will not run. I have sprayed starter fluid in the carb before starting the engine and then another time while starting the engine and it still won't run. With the starter fluid the engine seems to have some ignition, but it's small and won't be long enough to make the engine run, even for a few short seconds.
Thoughts?
