I can't seem to get my engine to run right. Never ran all that great after the break-in per manual. Now it is spitting fuel out below the cylinder head. I was planning on putting a new engine in it anyways. I would appreciate a little advice on which engine / pipe set up would work good for the truck. I'm not planning on changing alot, just want to drop a new engine in and go. I have always liked and trusted OS engines in my planes. Do they make good car engines as well? Also, will I be able to use my electric starter on a new engine? Thanks in advance.
