Hey guys a quick question.. I bought a GST 7.7 and i'm trying to get thru the breakin period.. the problem i'm encountering is it's like 4-8 degrees here in utah.. well the engine will run for about half tank and die.. it seems that if I keep a space heater behind the motor it runs better.. do these engines have to be semi warm to run properly? It's real hard to start when cold.. if I leave it in the house and then try and start it she fires right up..

what gives



thanks

dmanshep, The outside temp does have some do with how it runs. It is about 45 Degrees here in Tucson and I am going to wait to break in my wifes new engine when it gets alitle bit warmer, but you CAN break it in, in cold temps but you should break it in close to the temps you plan to run it in.

Also the cold air is more dense so you will have to tune it richer to compensate for the dense air. Which in turn COULD Create more power.

Running it in cold should not hurt it, tho

Good luck, and have fun!!
