I can always tell when a wanna-be-mechanic has been working on his (or someone elses's) airplane by the way the bolts0are installed on the clam shells that attaches the muffler to the risers.

Gary,
How have the wanna-be mechanics you've run across been doing this?

And better still, how should wanna-be-mechanics be doing it to be correct?
Not that I'd ever make the mistakes of a wanna-be-mechanic;)

the head of the bolt faces out. The nut is on the back. That means the bolt is being turned to tighten the nut. Big no-no. Also, although not technically required, I0would suggest putting a thick washer under the bolt head to hold it away from clamp to make it easier to get a wrench on it.

....And this bolt direction (opposite of the usual "head out - head up - head forward" standard) is clearly shown in Fig 78-1 of my Parts Manual. Interestingly enough, no washers are called out.
I guess they never looked at the picture.

you're right, washers are not called for. still it makes R&R easier.

Gary & Team:
I had two major problems when I first purchased my plane:
1 - The Carb Heat Shroud was totally broken off and void of tabs.
2 - When it came to doing my first Annual with this plane the Nuts& Bolts that held the clam halves together were totally rusted and frozen. Frozen beyond locking nuts. And in such poor locations that I could not get a wrench or socket on them.
I proceeded to weld new S/S tabs to the Carb Heat Shroud and ... Gary,0you are going to hate this; Totally a Wanna-be-Mechanic action ... I replace all the nuts and bolts with S/S - Allen Head Cap Screws and Locking Nuts. The action of an engineer not the FAA. Now I can access the all the bolts and nuts. Removal is easy since they are LOCKING nuts ... The bolts shear off. And as a side bonus I do not have a CO issue. 0Go Figure!
Hey, I'm not condemning "doing it the right way", I just did not like the rust and possibly of busted knuckles.
