Great power for its size, an excellent air filter system, and pretty smooth. Main complaint would be the AV being sloppy, but it’s certainly working fine.

I filled a couple of my AV with a urathane it worked well to reduce flex that little bit.

Would you mind explaining how you did that?

mettee · Jul 6, 2019

I used a devcon flexane, I can't remember the hardness.

I used some poly tubing on the inside and outside to make the "mold section". I'd fill a little bit and tap it down, repeat that a couple times and it will be full.

Let it harden for a day or two, remove the tubes(waxed for release) and trim any ugly stuff off. I molded a couple of them with the screw in place so it had metal to metal contact without having to clean out material. The urathane basically fills the voids between coils, you can't add too much diameter or you kill the av too much.

I did it 4 months ago and I didn't take pics. When I remove them from the saw to finish up some porting I'll get some.

Only did the lower three, I didn't think the spring on the cylinder would like the heat.

I remember another company had another good two part urathane, but the kit was $50 so I used the devcon stuff. I bet you could also mold in RTV

It firmed it up without affecting vibration? That would be sweet.

Wilhelm · Jul 6, 2019

How about using silicone to fill up the coils of the AV springs?

It was firmer but I have not noticed a huge increase(negative) in comparison to stock springs. I would say try a high quality rtv silicon(cheap) and see what you think. It stays flexible and would be cheaper than what I used(had it laying around from another job) if you have to buy it.

The cool thing if it's bad you just take a razor knife and cut it out. Mine has lasted 3-4 tanks of just screwing around, I don't get to cut all the kewl *s-word that you do.

Wilhelm that is what we are talking about

mettee · Jul 6, 2019

I have some old springs, I'll do one tonight and post some pics

mettee · Jul 6, 2019

Is it the 372xp cylinder spring that swaps to this saw? I've seen a couple people use that instead. But I bet it fatigues the lower springs faster unless you fill them

I’ll have to try that. I believe I have some of that rtv silicone.

I got the adapter, now I can run my Stihl lightweights. I like them a lot more than Oregon lightweights.

My bad, I am not fully familiar to technical jargon ("rtv" doesn't compute to me) and I may have missed the mention of silicone.
Sorry!
