I'm brand new at all this stuff, so go easy on me...
I'm building a Great Planes PT-40 ARF with an OS .46 FX engine .
The engine doesn't seem to fit in the cowling, though. The needle valve coming off the backplate makes it too wide. My question is, what should I do about this? Get a new engine? Put on a new carburator? Modify the airplane?
What do other people do when their engine doesn't fit?
Thanks in advance.
