Hey I have an Alpha 40 trainer and last night I had a ton of trouble trying to start it. I primed the engine and did everything by the book, then I took the electric starter and went to start it, but instead nitro started shooting out of the carburetor and my propeller spun right off. My plane has been started before by and instructor at the field, so I know it works. Also, I changed the glow plug so I know that is good as well. Any help?
