Hi folks,
Wondered if anyone has any ideas or comments on this one:
I got my secondhand 064 rebuilt a couple of months ago and it's generally been a pretty good saw. I only use it to cut the odd bit of wood up since I'm not in the tree service business. Back in the weekend I tried to start it up and it seemed pretty much impossible to pull the rope while trying to drop start. I took it back to my workshop and placed it down on the floor and tried again - but no difference.
So I took off the flywheel case and tried to turn the flywheel by hand - I could only move it slightly by a couple of degrees back and forth. I was meeting with some incredible resistance! So I removed the plug and then retried - this time I could turn the wheel and it seem nice and smooth and basically ok. Thinking "I've fixed it" I put it all back together and tried again. Still couldn't pull it round on the rope!!!
I took the plug out again, and the airfilter, and noticed a fair bit of wet around the back of the carb. Then I remembered that about a week before I'd done a compression test on the saw, in which I had I probably turned the saw over a lot, without actually starting it back up. And my mind got raceing thinking that perhaps this event was linked somehow.... After having that brainwave I tipped the saw upside down, still without the plug or filter, and pulled the saw over a bit. I believe the odd drip of fuel fell out - probably from near the carb area. Then I put the plug back in, and this time, with a lot of smoke and blubbering noise, she DID START and my smile returned. Since then the saw has been fine (I used it again the next day to check!).
I can only assume that I must have gotten too much fuel in the crankcase after the compression test, and that this resulted in a hydraulic lock in the BOTTOM of the engine somehow...
What do you guys think?
I guess I did my compression test wrong... should have unplugged the fuel line first
