The bench is covered in junk from several emergency repair projects (cars, trucks and tractors that broke).  And I wasn't going to do a chainsaw project this winter - but I'm bored. 

There's a decent 42cc Poulan engine on the shelf, and I just ordered a good carcass with a blown engine.  So it looks like I'm going to clear off the bench and come up with something else strange to do to a plastic Poulan for entertainment.

I know that feeling.

The heated handles on my 266 get warm enough that on a 40 degree day you need gloves to turn them on.

I have a 371/365 on my bench. Ported it last night. Going to run it today. I threw my muffler on it so I could test it and I'll get on modding his today sometime.


That porting did not mean drop the cylinder and hope the numbers come out great did it.   Just a little humor or sarcasm however you want to put it.

Nope not quite. Lots of grinding on these to get the numbers back. Almost 10° on the exhaust and transfers.

I ran one of Mike's ported 576 saws a couple years ago. I thought it ran mighty good. I felt of the heat coming off the cylinder and the way it sounded. Appeared to be one you could run all day?

The 576 was a work saw for sure. No compression increase on it at all.

Was fixing a PM chain today. Could see where the cutter was filed down into the drive link before. 
After what I just had happen in the chain build off. I didnt want someone coming back on me saying I did it. So I cut and replaced the suspect parts. 

Never thought about that before coming back on me IF.  So inspecting folks chains now closer.

Sounds like a lot of work and a real port job to me.   Like shaping, blow down, RPM's and flow.

I always clean/degrease used chains I get to inspect for damage.

Posted a bunch of photos in my 'Challenge Chain' thread on that other site.  I have seen:
- upside down tie straps;
- inside out tie straps:
- low profile tie straps used on full sized 3/8 pitch chain;
- broken off parts;
- all kinds of cracks in different components;
- hand peened rivets that are almost flush with the tie strap, instead of 'mushroomed' over;
- 'buffet chains' (a few STIHL links, some Oregon parts, a few Windsor cutters, some other type of Oregon cutters, some low profile/some not,  . . . ;
- and my favorite - the Pop rivet!

The Pop rivet really **** me up.   That is quite the list of crazy things people do to their chains.   I do not think I have ever come across anything like that.
