Sounds to me like you may be getting vapor lock. I would look first at your fuel system. Are you absolutely sure that the gascolator is the lowest point of your fuel system and then it is totally an up hill slant to your carb? If you have some weird curves that give a point where the fuel can vaporize it can cause a partial or full block. That would explain why it takes 2 hours and then runs ok again.

I got my preflight inspection done last Friday. Everything passed OK. So my test pilot taxiied to the end of the strip, did the run ups and then shutdown to get out and do a walk around. When he fired it back up it ran extreamly rough (check out the video link below the engine picture on my WEB page). So back to the drawing board, so to speak. Starts cold ok and runs well, right up to tempurature and for 15+ minutes. Shutdown and wait 4 minutes and restart and it runs rough. I'm at a bit of a loss since it runs fine from a cold start. I have to leave it 2 hours before it will start and run OK. All 4 coils and 8 plugs are sparkiing. I'm changing the fuel return line setup as there is a possibility of a vapour lock. If that doen't fix it I have an tech coming on Saturday to check the electrical. regards Barry Kruyssen Cairns, Australia RAA 19-3873 k...@bigpond.com http://users.tpg.com.au/barryk/KR2.htm _______________________________________ to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net please see other KRnet info at http://www.krnet.org/info.html
