Muffler Bolt torque value?

[AEROSHELDON]

I want to torque the muffler bolts on my DA120's and 60--I did not see values in the manual, is there a specific rating for this?

I actually have this written on my field box...
now I go look for my field box and be back hang on dude. I called DA for their spec.
brb
ok I wrote down 70 in lbs...
im 90% sure as my sharpie ink is wearinmg off. you may need to verify this.

TFAR........ That Feels About Right.

Typically, I use a lock washer and copper permatex. Tighten down using my long 4mm ball driver. I get one that occasionally comes loose, but more less since using permatex on bolts.

+1 on the Bunky method.

I'll explain the best I can. I use the gasket that comes with the engine without any washer's. I tighten them with the short end of the ball wrench till it won't move. Then I turn the wrench to the long end and put another 1\4 turn, maybe more maybe less just depends on how it feel's. I torque my prop bolts to 85 ounce inch and when I break the bolts loose on the prop with the L wrench it feels about the same on the header too.

Just don't use the gasket that comes with the engine use the method explains above and you'll have trouble free flights.
As for the prop I think it's very important to use a torque wrench especially with carbon props.
What kind of wrench you're using and what's the torque for a 170 engine ??

One action with several opinions, you just have to pick one and give it a try. I have always had great luck with my method without the first problem. Then taz says not to use gasket material. I'm not sure of torque will be the same if using gasket cause its squishy and gives to pressure.
