How does a 365 and 372 share same crankcase. But the 066 doesn't seem to do well with a big bore supposedly? And I know there not the same. But is the same concept.

Thanks for the video. My NH872 did not like a full keyway worth of advance. The saw would not start, only let out a few loud pops. I filed the key down to 1/2 thickness and advanced by that amount, saw seems to run great now.

@@IndianaDoug That makes sense, I just bought the saw a month ago. It seemed to wake up quite a bit after the first tank of gas, and the bump in the timing has made it a little more responsive. I am wondering if a muffler mod would wake it up further.

Scratch that, did the timing advance on the 895 and it's still a dog. It has a hyway pop up piston/cylinder, walbro wj carb, and still seems like it just struggles in the cut. I'm at a loss now, bought a holzfforma g395 and right out of the box was a much better saw all around, however I would like to find the root of the problem with the 895.

@@IndianaDoug I was wondering if you have any experience with the carbide tip chains. I've bought 3, one for my 12 inch saw, one for my 18 inch 550xp mark2, and one for my 25 inch ns872i. I usually use Stihl or husky c83 but I'm anxious to see how the carbide chains perform.

Interesting video .I have farmertec 372 kit saws and have timing issues. What I have found the flywheels can be way off either too advanced or too retarded. A keyway width might be too much advance. You will know it is too advanced is at full throttle in the wood it sounds like popcorn or misfires aka detonation. Too far retarded and at full throttle it rev up and down like a rev limiter. So I had advanced the timing 10* .At full throttle out of the wood and let off the throttle it will back fire too retarded timing still I almost have it figured out. I will try 3* .

I would like to see why everyone says the chinese 372 clone saws need their timing advanced via the removal of the flywheel key and advancing it one key width! Where is the difference coming from the chinese flywheel key notch placement? Or is it in crank notch or coil.. Husqvarna uses a built in key in their flywheels at least the x torque ones do.

Wait, is it really this simple to do a timing advance? The key isn't in need of filing nor the fly wheel? You can just straight up, take the key off, and advance the time?

Yes, you’ve been deceived🤣. Jokes aside, on this and many other models, yes it’s really that easy! Now some manufacturers depending on model, year, etc. have different setups. For example my ps series Dolmars have a “nub” cast into the flywheel. So to mod these you need to file it off.

The key and keyway are there (on this model) for indexing only, so you’re ignition timing is on par to factory specs. The key/keyway do not secure anything. The crank is on a taper and when cranked down with the nut, is secure.
