I intstalled a 235 that had been rebuilt about 17 years ago. it has been bagged up until this October, when i put it in. I'm comfortable that it was a good rebulid from a qualtiy shop. However I have about 2 hours of run time on it "tweeking up and down the dirt road" It runs like a top. However I have notice that once warm about every 5 min it will smoke a little for about 30 sec and stop. no change in running whatsoever. Am I in big trouble soon? Is it going to get worse? or all normal? rings sitting too long or too old even though they were new 17 years ago? Please advise thank you MIKE
