Well that would make perfect sense Bill but something is still not right with the IPC. In my picture you can see what looks like 4 tabs sticking out the 4 quaderants of the selector. In the IPC this part is clear and for 18574 and later. The IPC does not show this part before 18573. I see what you ...

Bruce, I think you may have it backwards. I think the early ones (such as my 18073) have the handle on top of the tunnel, as in the picture. The fuel valve itself is very hard to access.
The IPC is not too clear on this.....

You may not really know yet whether the mag was the originator of your problem, or a casualty of the original problem.
It's not always easy to figure out the chain of events in a failure.
Your mechanic needs to keep his mind and eyes open for clues.

Also, there is no need to anneal it as it does not work harden while forming and is non-heat-treatable. In other words it already is in it's softest form and will not change. I agree that 1100 it is not heat treatable. But it is my understanding that it DOES work harden by cold working. (More slowl...

Bringing up weather is an interesting topic with even more opinions. For me: I am a day time VFR pilot that thinks 2,000 foot ceilings and 5 mile visibility is a bad day to be in the air. So, I can tell if I want to go flying by watching the weather channel and looking outside if I wanted.............

Have you made certain that the scat tube and ducting behind the firewall is not partially blocked by debris?
Mice can put things in the darndest places.......

....... I understand how the scat tubing is run, but the pancakes had a funny shroud that stuck out into holes in the font of the cowl. The horizontal baffle in front of the engine has the covers riveted in place...... It sounds like you had the cabin heater conversion kit (Item 87 on Fig 34 of the...

ok, Thanks for looking. Any idea on where they kind of route? Your 170 is only 8 behind our SN! Ours is 18065 Well, it's not likely I can convey it very well in words much better than "kind of". The lines route below the crankshaft, crossing over to the left side of the engine. They then ...

When I bought a complete exhaust system from Aerospace Welding to replace my old pancake mufflers, I also had fit problems with the tailpipes exiting the cowling. We modified the pipes to fit the cowling outlet locations, rather than open up the holes to fit the pipes. We cut the pipes, adjusted the...

Jim: I haven't come through for you yet. I only have one of the two pancake sets that I used to have, still in my possession. The better of the two sets(the set I used up until two years ago), I now remember that I abandoned it in my mechanics scrap stainless steel pile. It probably is still there, ...

And I thought I was the last person to finally give up on pancake exhaust! :lol: Seriously, except for having to spend the money, I'm very glad I finally changed to the Hanlon-Wilson type, for two reasons: 1) I got tired of patching it every year, and 2) The cabin heat is sooooooo much better. But, ...

Perhaps it's because the ragwing had different baffles entirely ...than the later 172 system. :wink: Well, yes, that is certainly true. Perhaps I misinterpreted Richard Pulley's earlier post. :oops: I thought he said that his Airforms baffles for his 170A came with the upright pieces in front of th...

I got a PM asking about baffles in front of #5 and #6 cylinders. I think they are needed to keep #5 and #6 from cooling too much. My Airforms baffles have them but I do not have any pictures of them. Well, isn't that interesting. The Airforms baffles that I bought recently don't have the vertical p...

Mine came off awhile back, too.
I believe that the end of the rod was knurled, and the button was pushed onto the knurl with a small interference fit.
I doubt if they intended for it to last 64 years.
A little Loctite or epoxy will hold it on.

Of course, on my '48 Ragwing, there are no rubber bushings there.
64 years, and so far so good..........
