I think I've been infected by you all. I'm starting to collect chain saws now...
I picked up a nice clean looking 084 this weekend. ("It just followed me home, honest dear..."). It was reputed to have had very occasional use and the appearance supports the claim. 3' B&C, + 2 spare .404 chains to fit it. It feels like it has excellent compression (especially if one neglects to push the decomp button! ). I put some fresh fuel in the tank, full choke, 1/2 a dozen pulls and it fired up. Choke off, pull again, fires right up and runs for 3 to 5 seconds. Won't restart without choke, but then will act as above.
Alternatively, after priming with the choke and releasing the high-idle, it would start and run for slightly longer at idle. For those few seconds, it revs and accelerates freely when I pull the throttle, but bogs and dies very shortly thereafter. Fuel and air filters look clean, tank vent hose seems unobstructed (I even tried running with a loose gas cap -- no difference)_
After adding a bit of extra oil to the mix, I tried hitting it with a short blast of quick-start as it bogs and dies. The QS brings it back, so I'm pretty certain this is a fuel problem. I added a heavy dose of Seafoam, backed out the mix screws another 1/4 turn and ran it a bit more to work the Seafoam into the system. The saw actually seems to be running longer now, but that may just be because it eventually warmed up enough.
My personal motto is "Hope for the best, but plan for the worst." While I've seen Seafoam work miracles, I suspect there may be a carb kit in this saw's future. From the serial number, this saw is an early model, and from the wealth of data I was provided in the Beg for Manuals thread, it therefore likely has an CDIC ignition module and HT1 carb.
Looks like carb kits are still available, as is the fuel hose. The impulse line may be a problem though. Is there a universal tube that would be suitable for use as an impulse line?
Do the symptoms ring any bells with 084 owners? Anything else I should be looking at?
