Cliff notes: Dealer says it needs a new carb but can't get one. He rebuilt mine but it runs worse now than it did before. Mine has a Walbro carb and the only replacements I see online are Tillotson. Are they interchangeable?
Long version: I am a complet novice when it comes to saws. This saw belongs to my dad who bought it out of a pawn shop just after Katrina. I took the saw to the local Stihl dealer and told them I wanted the chain sharpened, the carb adjusted and to check out the choke/run/kill switch. (It seemed to me as if the switch was not working correctly but I don't remember the details of why. It was early summer when I last used it.) The saw was running and I had done some cutting with it early summer but it wouldn't idle properly. Sometimes it would idle but more often than not if you engaged the chain brake and took your finger off the trigger it would die.
I called after a couple of weeks and that's when I was informed that they no longer make a carb for my saw and that he had ordered a rebuild kit to try that but no guarantees. (WTH, if i say adjust the carb and you decide it needs replacing maybe that's something you should call me about beforehand.) I call back next week and he says kit is in but will be a few days before he can work on it. Call back 8 or 9 days later and he says "just got the rebuild kit in, will work on it in a couple days." WTH again. He denies remembering our earlier convo. Another week and he says the kit didn't work but he hasn't given up yet. After another week he says he can't fix it. He says compression is good, good spark, everything looks good, just won't run. (I have by now lost all confidence in this guys ability.) edit: the last time I talked to him he said "I have filed this carb everywhere I know to file a carb and it's still not working. I have no idea what he was talking about.
Now it will start but will not run long enough to even begin cutting. Just kinda chokes out or acts like it's not geting fuel. When it does start for any length of time as soon as you disengage the chain brake the engine revs to full throttle and the trigger has no effect at all.
An experienced tree guy took a look at it today. He poured out the fuel and added fresh. Checked the fuel filter and said it was clean. Took the breather off and inspected around the carb said he could see no evidence of fuel leaking anywhere.
I took the carb off and and was a bit concerned about the look of the intake. As you might can see in the last pic the intake is out of round and one side has been a bit mashed.
Any input or advice appreciated.
