Wippa snippa help???

i put a wippa snippa engine on my bike a few weeks ago and it was running fast and nicely. a few days ago up to now i have noticed that it isnt accelerating properly even if it is on full accelation. its a bit better going down a slight incline but is no good going up it still needs help by pedaling. i have already cleaned the carberator and have taked the exhaust off and even the air filter none of this helps much. The no exhaust give it a bit more boost but is too loud. can someone please help me with this problem. please???

You've probably worn the thing out. That engine was designed to spin a piece of nylon around in a circle, not propel a bike.

A friend put one of those engines on an office chair with wheels. It eventually blew up because it was not strong enough for the task. But it was fun while it lasted.

MotoMan is right , but you could try adjusting the fuel/oil Ratio away from Standard to see if that can help.
have fun , but you just may end up `detonating` the thing...!
