I had a problem Sunday when it reached 100 degrees outside. I ran it about 30-40 minutes and just shut down and would crank over and try firing at times but wouldn't fire. Went inside and came back out and fired right up. I was thinking it was fuel but my friend is having the same problem for the past 3-4 years. I have a 1968 140 with a Kohler 301 12hp motor and he has the same motor but in a grasshopper mower. Anyone else have these problems or answers? As to do with electrical. All vents, grills and air cleaners are clean so not like it's getting air. These motors only do it when it's really really hot out side. Any suggestions would be great.
