I pick up one these for my low wing trainer and so far it's been a pain in the rear. Problem is it starts up and runs for abit then dies, it then may start back up or may not. I done all the normal checks for this and follow the tips I found here but still the same thing. I have this mounted in a Tower Hobbies Voyager 40 MKII and for now the engine is mounted right side up. Thanks for any help.
