Well I had sprayed some Seafoam Deep Creep in there just to lube the rings up....mainly because I've had weed eaters not start because the rings were dry from storage. Plus I didn't want to scratch the cylinder, I didn't think squirting a little lube in there would change anything really. But yea, it's definitely got some compression whether it's reading right or not.

Any spray in the top end will increase the compression reading.

I have to remember that. I have a can of Seafoam that's been dormant for awhile. (1) Remove spark plug (2) Spray in Seafoam and turn it over a few times (3) Measure compression (4) Take picture of gauge and place saw up for sale.

I always ask the seller of they did just that. Once I get saw I do both tests to compare results as well.

Pretty sure I figured out why it was "losing power"





Took the carb apart to clean it and the plate over the diaphragm was totally full of sawdust. It came out looking like a miniature salmon patty or something haha. It's all cleaned up and re-installed now. Only problem is that one of the four diaphragm screws is stripped. That shouldn't really be a bid deal as long as the other three are tight, right? Don't figure I can heli-coil that little thing.

Also, is there any "correct" orientation of the air hole in that plate? I re-installed it at the lowest point, hoping to keep the dust out of it, whereas it had previously been installed facing toward the air filter I believe.

The build up should have caused the saw to run lean since it limited the movement of the diaphragm. I've had to replace the ignition coil / module on two of these. They miss fired and wouldn't rev when hot.

Still a good possibility....luckily I've got a Super parts saw. Also looking like I'm going to do a muff mod on the super muffler and hopefully keep it running cooler. The stock muffler on this saw, exited directly onto the case.

Make sure the muffler from your super will fit onto the WB before going through all of the work modding it; some of the later 028 mufflers WILL NOT fit on a WB.

Good on your friend! One of my friends, not much into saws, brought his over that is older than the one you scored. His father bought it new, and never took care of it.

So now it leaks bar oil like mad, and I need someone to tell me how to put a stop to the leaking. It seriously leaves puddles everywhere it sits.

I was able to get it running, but not stop the leaking bar oil. Any help and/or advice would be GREATLY APPRECIATED!

Thanks,

Cliff
