Acceleration decreased after cleaning and lubing clutch

[DisillusionedPrepper]

No trouble.

I have a "thing" about opening engines over, and over again... I DON'T LIKE TO!!!
The more times you open these cheap engines the more of a chance of stripping a thread somewhere.

Try your new rollers first. You may have to go lighter than you think because your control spring is now weaker.
Something else that I like, and use is the Malossi torsion controller. Its a simple nylon type "pad" that sits under the clutch itself, and on top of the spring. It sort of pre-loads the spring, and eliminates the metal to metal contact between the spring, and clutch.

If they do not have them for the 150cc engines, I plan to make one. It's just a nylon shim about 1/4" thick with a groove that the spring seats in. Simple enough...

Post up your results. We all like to read a success story, and the trial, and error that goes along with it.

Best to ya!
