I’ve got a Husqvarna 435 chainsaw I’m trying to fix. I was told it sat for several years without being ran and has only been ran a few times since being bought.
I got it home tonight, dumped the old gas, put new gas in it. Primed it choked it. Pulled on it a few times. It cranked up, but ran pretty fast while on choke and then died (maybe 5 seconds). Choked it again, pulled a few more times, it ran again pretty fast on choke, then died again (maybe 5 seconds again).
I looked up the jet adjustments and the idle adjustments. Turned them all tight and then turned them back 1.5-2 turns. Same as above. I spent about 15 min trying to slowly adjust the idle screw and the low jet trying to get it to do something besides running for 5 seconds, burning up the fuel during the choke and then sputtering dead. No luck with that.
I pulled the carb off and cleaned every port I could find. I could blow cleaner through the jets and every other hole without any issue that I could tell. Nothing looked all that dirty to me.
Put the carb back on and it did the same thing.
It’s obviously getting fuel when it’s choked/primed but as soon as it burns up that fuel or if i try to just give it throttle it immediately dies.
Any suggestions on what to try next?
