Figured I'd be in for a carb kit at least as it was stored for a number of years. I'm not sure what else to look for though and would appreciate any suggestions for quality parts. (Canadian if any)
So quick as to the what and why. It's tge model with the 1 fuel line choke lever side.
After tuning it ran fine and an experienced guy said it's OK but could be better. Fine enough to run it. L +1 H +0.5
Filter is clean, undamaged. Plug is used but good blue/purple spark, gap is fine.
Coil gap fine
I keep it very clean but I do like to use the air gun if that's a consideration
Flushed the tanks when I got it, filter seems OK to me, new fuel line was necessary
Cleaned the carb but didn't replace any parts
I'm running mix at 4%, I'm going to switch to 3% though to see how it responds
Will add my mix as of now is over a month old but gas was never in tge saw longer than a week. Will mix fresh gas
During and after tuning I monitored temps regularly and rpm for overspend. I never went wide open for more than 5 minutes straight (firewood), and never without load other than during brief tests as the manual describes. Spark plug was always normal or rich.
I think that's everything, now the how.
Start saw, slight blue smoke after 3 or 4 pulls. Steady idle.
Let saw warm up. Steady idle, no smoke, maybe 3 mins.
Get to cutting, after a couple minutes it suddenly started overrevving. Consistent, no sputtering. Saw was cutting vertically, tip down 45°
Finish cut (2 seconds, maybe 3) come out of cut, saw dies.
Check tanks, forgot to fill them but there was an amount in there, both. Fill tanks, attempt to start, no fire
Check filter, plug, piston and chain move freely, no carbon build up
Attempt again, bit of blue smoke, no fire. Change plug, another used plug but still fine. Attempt again, puff of white smoke
Take a 30 minute break to read on this, come back, compression test 140 psi (with a very old push and hold type with a relatively hard nipple so it might be higher, likely is)
Attempt to start, fire. Hold WOT, won't open up, half speed maybe and 4 stroking with blue smoke. Let off and it dies
Will post any requested pics and appreciate all responses
