Hyper 7 .28 engine trouble.

Hi,

I am having some trouble with the hyper 7 .28 mach engine. When the car is stationary the engine can suddenly making a loud prolonged (almost defaning!) noise and start moving forward by itself. Do you know what might be causing this?

Thanks

RE: Hyper 7 .28 engine trouble.

I think the HSN may be too lean so ill change that. There is still lots of smoke coming out when accelerating so can i lean the LSN a bit more? I did see air bubbles at times when the car started to scream really loud when stationary so i'll change the tubes just incase
