I just picked up some C85 loops. Going to try them out.

I have 3 different sizes of chain, so that means I have to spend north of $1,500. Buying new bars to convert to 2 sizes of chain wouldn't help. I have been finding discount loops online and buying when the price is right so far.

Yep. I have to take em down on every chain I get. I used to sharpen at least 3 times before touching them, about 20 years ago. Now I have to put every chain in the chain grinder, or even worse, use the belt grinder to remove safety humps or those fangled "vanguard" folded rakers. It's...

Wow! Pretty cool!

I get about 18-20 wheelbarrow loads per cord if I stack it on there. Around 35-40 splits/load, sometimes more. Around 700-800 splits per cord My son stacks 50-60 splits on the wheelbarrow, which looks more like a rolling jenga tower. He can't maneuver with it like that, but he can move a pile...

I built myown splitter exactly the way I wanted. Used a ford van axle. It runs down the road at whatever speed you care to go.

That cylinder sound like it runs real nice.

Crazy

Pressure waves in a 2 stroke move at the speed of sound. That's why we can tune the exhaust and intake. If the waves moved any slower, you'd never get 'em to run. The port's are not open very long at 12-16k rpm. At 14,000 rpm, one full turn of the crank only takes 4 THOUSANDTHS of a second...

Here is one of the pistons I took the "wings" off of. Still running strong in a high strung ported saw after about 4 years. I don't remember how much weight I took off, but it was a lot lighter.

I have removed the flares from the sides of pistons in husky 350's with great results. It really opens up the transfers. I'd be willing to try it with a 372 as a way of lightening the piston. You don't have to worry about ripping the rod bosses out of the piston because the piston is always...

Oops, missed that!

Wow. Looks rough, but for $27, as long as it cleans up, I'd be happy.

I'm not sure what's in this one, but it runs ok.

The thing with popups is the ridge can deflect the charge up and mess up the loop scavenging. A more gentle slope, rather than a ridge, can work well if done right, but can still leave a pocket of burned gasses at the rear of the cylinder. More compression isn't always a good thing. It makes...
