I just put on a K&N filter on my 150cc Yamaha clone engine..its a Chinese ATV (Marshin 150). It has a Mikkuni Carb with auto choke. It was runing fine but since I put the new filter on it has a low end dead spot. when the rpms are up runs great. tried to adjust the carb with no effect.

Thanks for any help.

rejet maybe, but idk

 

I just checked, my main jet is a 115 how much higher should go?? Could I lower the needle or is it better to re-jet..

Thanks Alot!
