That's right, got the new intake pipe and shim and all. Wasn't sure about jetting or how it works besides vague speculation, also new to carburated engines. Not really sure what to look for in terms of jet or where it is, but I'm going to do some digging to find out.
The engine itself basically sounds like it's running when I have it going with the pedals, and it makes engine noises when I give it throttle but it dies down immediately, hence my confusion.
I'm going to start with spark then try jet.
