Ty175 Runs.... But Will Not Accelerate Cleanly?

Featured Replies

New to this forum.... and need some help please?!! Bought a Ty175 a few months ago that has stood for 15 years un-used.

Rebuilt the carb, fresh fuel and new plug and she fired up first kick!! Well chuffed!

Had a problem with dirt in the fuel, so have Pet-Sealed the tank and now have very clean fuel. Bike still starts great, but when I select first gear and pull away, she starts to die??

If I slip the clutch and keep the revs up, she will keep going and she will eventually burst into life?!! That's OK, but have tried her off road, and it is very hard to control like this??

Any ideas???? It is almost as if the carb is over fuelling, but have checked jets, needle setting etc. and all seems good?

Any help would be greatly appreciated!!

Cheers!

symptoms sounds like a blocked or part-blocked pilot jet. This time, remove it and have a look through it before you clean it. If there is any crap still getting to the float bowl the pilot jet will keep blocking

Crankcase seals need changing. Not difficult,can be don without splitting engine.
