I recently picked up a 2002 model 346xp. The saw had been sitting for several years. It had the plastic intake clamp so i took the cylinder/intake apart to upgrade to metal prior to running. After that it fired right up and runs good.
The problem I'm having is with carb adjustment. It has Zama C3 EL-18. Everything I can find says factory settings are 1 turn for both low and high. I am at about 400' elevation so normally factory settings are pretty close. It was running very lean at 1 turn on high so I started backing out the high jet. I ended up at just over 3 turns out before it was wasn't racing but still barely able to get a faint 4 stroke and plug looks barely safe. I thought it must have an air leak and I suspected crank seals since I hadn't replaced them or vac tested yet. I just vac and pressure tested it and it's rock solid with no leak down. I took the carb apart and can't find anything unusual.
Should I worry that carb is so far off from factory specs? Any ideas? Thanks.
