Once the eng warms up and I shut it off for awhile, it really takes a long time to start it, lots of cranking and I usually have to pump it like crazy and then it starts up and runs rough for a minute.

What's the outside temperature when this occurs?? Sounds to me like hot weather and vapor lock in the fuel pump or gas boiling in the carb. after heat build up after shut down. For the carb problem you need a carb base insulator. Contact Bob Shewman
[email protected] or 1-610-933-6637 he has the best one I have seen. The pumps vapor lock problem on hot days with the new gas is an unresolved problem at this time. G.M.
