This is a few pictures showing a saw ran first with a factory muffler but ran on 32 to 1 oil and secondly after a gutted and improved muffler .
The first pic was taken about a year ago .I lifted the top and did a real simple port job .Just widened the exhaust polished the intake type .At that time I gutted the muffler and added the second port. Much like a factory duel port . Prior to that there was a slight build up of carbon ,not bad though .
The second pic was taken Saturday .The piston was not touched .It is just as it appeared when I lifted the top .That saw has had approx 30 to 40 running hours since a year ago .It wasn't ran tank after tank though .15-20 minutes per time cutting stuff out of a pile to splitable lengths .Almost no carbon .That piston had a nice slick coating of oil when I lifted it .
That cylinder is going to be reworked to raise the comp for some improvement in performance .I thought it noteworthy to post just to show what improving the exhaust flow does for an engine .Draw you own conclusion on the oil .
