Hard starting when warm

[edtheguy]

After running a while and shutting off. Difficulty restarting

 If you mean that it turns over very slowly, like the battery is low, that is a common problem on the first gens.  Some people have had success installing a heavier gauge battery cable.  Others have changed to a newer 4 brush starter.

Another option to those mentioned by Freebird that has worked really well for me has been to remove the OEM starter and clean the dust out of it real well, paying very close attention to the build up between the armature and communtator segments.. Kept clean my OEM 2 brush starters have served me well and worked as new when kept clean.  If it were mine I would also double check stator output at the battery when warmed up as a tired stator can cause hard starting when warm too. So can carb issues, dirty plugs and so on and so forth... Maybe a quick youtube video of what its doing would help us help you diagnose whats going on..
