Thanks for thinking about me for a parts supplier Jethro.Lol I only have 1 or 2 extra coils & I'd like to keep them for my saws.The one on Ebay for $47 is a good price considering it's new.I don't think Bob Johnson is going to beat that price at all & he charges shipping.The going rate for those coils is upwards of $60 or more.

I had a friend stop by today with a couple of power heads he had cleaned up and put together. He does not participate in the forums but I can put anyone in contact with him if you are interested in either one.

This guy is very meticulous, blasts and paint the mufflers or uses new mufflers, goes through everything and replaces anything questionable. He also sells on e-Bay under the name 1twomachine.

I was talking about my sp81 on the 10-10 thread, but probably better to discuss here. I just fixed tank valve and took my 81 to finish cleaning up at a job we took some mill logs from. It's not right, I'm not getting full revs out of it. Just isn't as snappy as I'd expect this saw to be. It still runs pretty strong, but is leaving some power on the table. Gonna get a carb kit and see if that helps. Currently have hi and lo adjustable carb from sp80 on it. Should I rebuild that or do you guys feel the original fixed hi jet carb would be better? I pulled the original carb apart when I got saw last week. Looked spotless inside but saw wouldn't fire with it on. Put sp80 carb on and it fired right up.

Here's a sample of the size logs I was running it in. Sorry no glamor shoots of it in the wood.20190817_123002.jpg
 
Check the points. Mine was behaving like that and I narrowed it down to the ignition and eventually the points. Cleaned and re-gapped and found quite a few new RPM's. The fixed jet carb should run just fine -- maybe a hair rich, but completely acceptable by most folks' standards.

I have an sp81 that did the same thing fir awhile. It had the fixed jet carb. Sdc51a. Ran good but not great. I put an ignition chip in it and it made a huge difference. So i agree with pogo. Check the ignition first. Then go after the carb.
