Interesting. don't get me wrong I like this TT engine a lot as it is very easy to start (if I can actually get it to spin over LOL) I would hate to give up on it but I can't count how many times I packed all the gear and plane into the car, got to the field, fought with it for 30 minutes or more only to get pissed off and pack everything back up and head home. I am thinking of buying one of those heat packs they sell at Walgreeens or Walmart for sports injuries and wrapping it around the engine before starting it. Does anyone know how warm those packs get? It does not have to be real hot or anything just as long as the engine is at room temp it is willing to spin over.
