I just bought an 89' 300E yesterday and one thing I noticed was when starting it over-night after not running for 10 or so hours it doesnt start before you crank it about 3 times for 5 seconds. Opening the throttle doesnt help much either. Two things that might be of concern are that there was 1 gallon of 87 in the tank at one point. Secondly, the guy I bought it from only started it once every few weeks to keep everything loose so to speak. Could the lack of operation be suspect to the cold starting issue?
