Thanks Howard and Ross,

I am working on a 47 custom super that uses shims as shown in photo, lower right. Ross, you are right I need to decrease thickness, but right now I have a single .030 shim that yields and end play of just over .007 - the high end of the recommended range. So, I planned on making several shims and stacking them, shooting for a thickness of .028.

Howard, your idea of sandwiching between Masonite is brilliant.

Ross, am sending you a PM.


Thanks guys.

I am attempting to make some rear axle shims from brass sheets. Trying to keep things flat and unbent. Do you folks have any tips? So far, I am thinking of using contact cement or something, and glue the sheet to thin plywood. Then I could drill and file without bending the shim stock. How would you guys do this?
Thanks,
Mark

Howard, you are infallible....91 DOES fit. Long story, chalk this up to numbers confusion at the parts desk. I'll try and get the x-ref expanded to include 21st series 356. Napa's database is incorrect.
Thanks,
Mark

Hi Guys,
I would like to try a modern pellet type thermostat, with the standard temperature range, for my '47 custom super (356).

Our parts x-ref for the 48-50 356 lists Napa #91 but it has a flange that is too small. Napa's online search for a '47 356 is incorrect - parts 530060 and 530080 are also too small.

Max has the pellet style, but in a high temp version.

Have any of you folks found a standard range in a pellet style?


Thanks,
Mark

These are the fittings that Tim sent. Left side with washer to the carburetor. Used Loctite blue on threads. After 100 miles, no leak.

Thanks to all who shared ideas...

I spoke with Tim at Daytona, the source of this carburetor. This is common problem for them, caused as James described and not necessarily from overtightening.

He suggested replacing the fitting with one that has larger shoulders that will accept a soft washer. He also suggested judicious use of blue locktite on the threads. Fitting and washer is in the mail and I will let you guys know how it goes.

Thanks to all,
Mark

My understanding is that npt fittings seal with tapered threads. So, wouldn't a washer move the fitting out from the taper and make things worse? Just asking....

Thanks guys. Excellent ideas as always.

Hi Guys,

The inlet fitting has bottomed out and leaking. (carter 531S) I've found three possible "fixes" - none ideal.

- high grade epoxy - easy and quick, but probably would ruin the carb as a core in the future.

-drill oversize and tap next size larger - concerned about cracking the case

/self tapping fitting - same concerns as above. Not sure I can find one small enough. I think this is 1/8 npt.


Anybody been here before? Recommendations appreciated,

Mark

Hi Newbie,
Until the real experts can weigh in, I believe you are looking at the hook up for a heat tube from the exhaust manifold. Perhaps a site search in this area will find some pictures.

Best of luck

Mark
