Hello from Missouri. I'm 60 years old and I just cut firewood for personal use, however love tinkering on chainsaws and have started kinda collecting saws. I have ms170,180.024wb, 024 super, 025, ms250, 026, ms261 (primary saw), 028 super (which I'm having trouble with), ms290. Built the 170 and 180 from parts and rebuilt the 250, several carb rebuilds.Now my problem! 028av super. Replaced seals, no vacuum/pressure leak. Compression 140. Has good spark. Rebuilt carb. New fuel line/filter. H/L set to 1¼ out. Haven't changed impulse or boot. Getting fuel. Won't start, if does won't idle. ???
