Hi all, My GF’s dad just bought a well used 046 arctic. I was listening to him cut with it and it sounded a bit lean to me so I told him I’d get my tach and check it out. I’m guessing this saw is from the 90s, it did not come with limiter caps on the carb but I don’t know if someone else previously removed them. I also went ahead and ordered him one of those China dual port mufflers off of eBay with no baffles or screens. It had a single port muffler. Fast forward to today. I pull the muffler. The piston has a little scoring on the exhaust side. (Maybe carbon scoring?) I checked it with a snap on gauge and it blows about 140 psi, otherwise the saw runs great. I tached the saw with the new muffler and it was turning just over 14000 rpm. In order for me to bring the rpms to around 13,500 I only have to turn the H screw about 1/4 turn from full lean. Also the L screw is only about 1/2 turn from full lean. It accelerated good and cuts really well overall. What I’m confused about is there is a sticker that says 1 turn out for both the H and L screws. If i go one turn out it only turns about 9000 rpms and the L screw loads up the carb so much it smokes at idle. Do these settings seem right? I figured it would be over a turn out each screw at least, especially with the muffler change. Thoughts??
