I'm home but the sleep/wake cycles are still a mess...I did spend some time today with the 1-51 from Cliff and it is now a runner. Interesting challenges on this one, kind of like the old Dodge automechanic "find a fault" test.
Spark was good but the plug was the wrong one and would not connect with the boot/cover...that one was easy. The Tillitson HL 63 on this one was more trying than any flat back I ever tackled, absolutely could not get it to hold pressure, leaking out through the impulse passage. Finally gave up on that one and picked one from my big box. After several attempts I finally noticed the new spacer/air box gasket did not have the impulse hole in the right place. After that it wanted to lean out after running WOT for more than a few seconds, not sure why it got better but it did seem to come out of it. I installed the bar and chain that Cliff sent with the saw, seems to start and run pretty well now. I will put this one in some wood before making room for it up on the shelf. I will add some photo's later when I get on the computer again (Kindle tonight)
I had an equally trying session today with several Walbro HDB carburetors, two out of three would not hold pressure with lots of tiny bubbles leaking out under the fuel pump cover. Anyone have experience with this? Is there any way to make them seal properly? I tried new gaskets and diphragms but no joy. Anyway, I did get the 655 running as it should in spite of the set backs.
Later...

P.S. Andydodge, great find there, you will be spoiled for sure now. The 82 cc 10 Series saws are some of the best McMulloch ever made. Use good oil, 40:1 or even 32:1 and never, ever let it run lean.
