I have been having problems with my ride loading up and burning rich and blackened plugs. I have completely went through and rebuilt the carb and cleaned all the orfice holes and soaked the carb. I noticed the diaphram was burgered up on the little tip and would not seal the diaphram when installed. I have a new one ordered and would like to know how the diaphram would effect the way my ATV has been running since the diaphram was defective. Thanks for any info. D.T.
