Default Carb question (Predator 90)

I have a 2004 troy lee addition 90cc, and it seems like the carb is cutting out from time to time, I can get it to start and idle and even rev just above idle then it bogs, I play around with the throttle move the gas lines around and some times it clears and will run for a while like nothing is wrong. I checked the gas flow from the pitcock and the fuel filter and it seems fast and steady. I am not sure what type of carb is on the preditor 90, I really don't know much about them, I have seen different sizes called out. I did take the carb off and clean it out, made sure the float was ok and the bowl was clean. I have never rebuilt one before. Just wonder if the carb rebuild kits are worth trying.

I moved this into the Mini section to see if you get any better luck with your question.

What kind of filter are you running on it?

Your carb is a Sun world H68K. Rebuild is not neccessary. Take all the jets out and clean them spotless. Then give the carb a good once over with carb cleaner and re-install. Let us know what happens.

I have seen mikuni 16's on Pred 90's but either way it is like jarhead says take the main jet and pilot and blow them out with air or something. Clean the gunk out of the bottom of the bowl and let her rip. The only other thing I can think of is a muddy stator which is always a good preventative maintainence item as well.

Chris,

Thanks for moving this to the correct forum area. Thanks to all that replied.
I'll look at the stator, the kids were riding thru the mud in the spring and come to think of it that's when the problem started. I cleaned out all the carb parts that seemed easy to remove, it was pretty clean inside.

The Fuel filters I use are the OEM little white inline filters from the Polars dealer. Nothing is modified from the original Date of purchase, well except for the Coil, From day one there was a problem of buring plugs, the Polaris dealer and Polaris tech support could not find the problem (hair line crack in coil), it took the Kawasaki dealer to fix it

Take a look through Spikes webpage. It has a very good set of how to's to fix the little problem areas to include the proper way to clean up and protect the stator.
