Hello Everyone im am new to r/c and i have a small problem. i got a r/c car with no engine and i purchased a .21 GS Racing engine off eBay (im sure its not very good but oh well

) any way problem being is the fly wheel i have fouls with the carburetor when i attach it, i believe it is the angle of the carburetor, anyhow i was wondering if anyone could offer advice on what to do, new flywheel? Some kind of spacer? A cheap solution would be nice

Advice is Much Appreciated
Cheers Tony
