My '03 Kodiak 400 has a stalling issue. When it warms up to temperature (about 6-8 minutes) It sputters out and dies. Restarts fine with a little throttle. Once it has re-started then it runs about 30-seconds and dies again. The longer I let it sit and cool, the longer it takes to die out. This is after a few other major things were done recently... New stator; rebuilt carb. Coils have proven to be OK.
So, I've tried another carb (off my 2000 Kodiak) and the '03 Kodiak still does exactly the same thing... Dies after about 6-8 minutes, otherwise runs and idles just fine. I'm now thinking it could be a stuck starter plunger. It may be partially sticking which, I think, would cause the stalling issue once it is warm. I've had the '03 starter plunger in & out of both carbs a few times due to the carb-swapping. Am I on the right track here? Is this a common issue and is it adjustable?
