I have a problem with my .15 Leo engine. When I pull of (after engine has been running for a while) there is a slight hessitation, then it picks up speed slowly and then all of a sudden it's in it's power band and then reaches top speed quickly.

I drove with someone this weekend that has a Timaya car (the 50mph+) and he's one is totally different. He's car gets to top speed alot faster. Because he has two gears he's top end is faster.

Anyone have ideas.
