My buddy has a formula 500, And once it gets warm its hard to start and some times wont start at all. It seems to start better by pulling on it rather then using the electric start, and would anyone know what the setting would be for the pilot screw(jet). Any help would be appreciated........Thanks

is he shutting it down as soon as it stops moving? maby let it idle for 30 secounds first.

If letting it idle before shutting down doesn't fix it my guess would be the Crank seals are shot. :banghead: Does it start OK when it is cold???
