i have a 371xp with a bb kit ported. The saw was runing to lean wide open. I'm trying to get the most rpm out of it that i can. The guy at the saw shop said that he had herd that if u put an extra gaket in on the metering side and bend metering arm up a little that u would get more gas reserve in the carb so it wouldn't lean out wide open. I tryed it and the saw just floods. I have the L side all the way in with the stops cut off. Is this something that works? Has any one tryed this? any info would be grate.
