Update: I got a call from Makita tech that worked on my saw this afternoon. He said he replaced the carb . He said the saw definitely would not idle properly before .He said he noticed in my notes that the dealer had cleaned the carb. He said we don't do that if there's issues with the carb it should be replaced.He aid there's a brand new carb on the saw now he said they only made a couple cuts with it but it should be fine. I mentioned my concern of existing air leaks and he said the gaskets were all fine . Didn't have much time to talk today he gave me his ext no. and asked that I call him back Mon. afternoon I'll get more details then. They were shipping the saw back this afternoon said I should have it by Tuesday 4/25. Pretty quick I figured it would take at least a couple weeks. I hope it's really fixed this time!
