Mornin!
I’ve been slowly working my way through an 084 and I can’t get it to idle. Fires on choke, will start the next pull and run a bit but won’t stay running for more than a few seconds. Then it’s gotta go on choke again to fire again. I have cleaned the carb and put a new kit in, replaced the fuel and impulse lines (fuel line was cracked, impulse was not), set the flywheel gap with a business card and gapped the spark plug to .5mm (couldn’t find the correct gap for an 084 on google and decided it couldn’t be much different than an 088). Compression is pretty good. Got it up to 150 on The gauge and decided to quit pulling on this monster. The next step is a pressure and vacuum test correct? I’ve read enough posts on how to do it but I don’t have a pressure/vac set up. Is a harbor freight special good enough to do the job? Do I need something better? Or should I just strip the saw down and see what a saw shop would charge me to do it? Any advice would be very much welcomed. Pics for attention.
