Hi Gary:

Welcome, and enjoy your 300E! The search for words like 'warm', 'idle', 'start', '300E' will turn up a lot of threads - one of the better is 300E rough starting when warm. . . . It also has links to threads by Benzmac on this issue in the responses, so click on those as well.

Enjoy your ride!
