Just to keep you confused, not all saw motors run CCW. Lot of gear drives run the other way. I'll let you guess why.

Well, I guess having gears, guessing two, engine gear turning cw, the other, bar side, ccw for the correct direction for the chain. I don't know any thing about gear driven saws. If it has four gears, cw, ccw, cw, ccw.

Went to run one of my 475’s which I purchased with 3 used bars & chains, 36” & 2 24”. Had the 36” on and it started cutting crooked and binding up in the cut, took it off looked bar & chain over, chain teeth are definitely not even but can’t tell if bar is bent or not. Put one of the 24” on and pretty much the same thing. Will inspect later when I have more time, original owner may have done the damage, he was a real hack

This one didn't work at all. I could hold the fuel line up and down and fuel would flow back and forth. However, I could only blow one direction. HAX18-DF0 1/8 X 1/8 CHECK VALVE, KYNAR, NATURAL, VITON DIAPHRAGM. Our disc based Check Valves utilize a free floating design and can be used in any position with an immediate response to change in pressure or flow. I made a couple of test cuts with the 406 check valve posted above and it didn't cause any performance issues.

I also got these checks, but I don't think I'll use them since they are made of silicone. Too bad, the size was perfect.

No chain brakes on neither.

I dont think shes fat here is a 2300av with some extra pipe weight . The 3700 power to weight seems ok to me .


The mini 25 was faster cutting but its only 40 degrees and I adjusted it more. Need to fab an outside the cover adjustment for the 2300 carb.

I've had 3 versions of that saw.
First is the thin ring 3.7 w/o powersharp (kept), then found a thick ring 3.7 with power sharp (gave to cousin), finally a gray/black saw thick ring no powersharp.
A lot of the red black 3.7 saws are 3700s (without the slotted cover and hd starter pawl) which are more desirable, generally have better compression and noticeable performance over the 3800 based saws with thick rings and chrome cylinders. That said I've had a lot of 3400 and3800 saws and I can honestly say I have never seen one with a blown piston. And they've all run pretty good too. The powersharp is easy to remove at least.

I have a crushed 4000 with a good cylinder, piston, top cover, filter cover, carburetor etc. I may make a 3400/4000 hybrid but I haven’t seen a blown up one yet.

Who needs one blown up, just do it, won't regret it.

Silicone should hold up real good if running e-10 gas.

Picked up a 14" bar that fits the S25da saws. Only designation on the bar is 44077 DU. 14 3/8. What is easiest way to determine # of drive links?
