I have been having an on-going engine prob. All 3 of my eninges are doing the same thing. I can start them, and they will idle just fine, I go to run, and they go for a min or two then they just stall out. As far as I can tell, I have not been over-heating the engine.

If it matters the engines are a TH 46, TT 46 and a TT40.

the TH is a rebuilt motor that I just broke in. I am wonering if the low idle is right.

Thanks!
