Yea, I was referring to the Bottle, and I think the Blue Bottle is the stronger stuff. Thanks for the clarification.

I started using the stronger stuff after I had a 460 that I did for a Tree guy spit the muffler bolts 3 times in a month. They were super tight, with the regular Loctite, and it kept spitting them! The Heavy Duty stuff cured the problem.

I use ultra copper RTV on the threads of exhaust bolts. For high temps it works better. It's an old trick to keep header bolts from rattling out on race cars.

Putting a 576 back to gather and one of the stuffers (or what ever its called) on the crank is really loose it will snap on but any movement or bumps it will fall off. Is this normal or should it be replaced?

Do you use a torque wrench and tighten them to the spec in the relevant workshop manual? I do (and use loctite) and never have had a problem. Typically I find the spec is way tighter than I can achieve with a T handle driver.

I don’t think it would hurt the saw too much to run it without the stuffers? If it were my personal saw that’s what I would try.

Well clone blue got some covers that I had left over and put a deflector on the muffler cover and screen a little face lift. Lol. Here's the final port timing numbers I gave it and squish. Ex-100. In-80. Transfers-123. Odd numbers but it's strong. Squish is dead on at. . 021. And MustangMike it still has a baffle in it but modified it. Lol. IMG_20181102_132910.jpgand I put oem Stihl ristpin and baring and clips I'm going to pole the cylinder next week and but caber rings in it then back to fixing other people's saw's funner moding mine because I know what I want. Lol.

I'm pretty sure that I tighten things a bit beyond the recommended torque settings, and for the most part, no problems, but every now and then …


The saw I referred to, which just kept coming loose … and another saw, the muffler bolts came loose after it had gone for over a year w/o any problems!

I just figure, better safe than sorry. I can not predict which saws will have this issue, or not.

Finished putting the 066 back together with the new tank handle and muffler mods. Sounded good, and was very responsive.

The owner should be getting it tomorrow, looking forward to his comments.

Glad to hear it is strong, that is what matters.
Funny how every saw runs a little different but I already new before doing the port work on this one I figured it would be a strong runner but I'll be putting another kit ms660 and ms440 together and I'm sure I'll be putting some oem parts on them to get them to work right Lol
