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
