Piece of carb for corrosion test

[flyguy]

I am looking for a piece or part of a Stromberg main casting. Can be just a broken piece if you are sure that it is from a Stromberg for a 65 or 85.
Please PM me if you have something.

Re: Piece of carb for corrosion test

What are you testing? I have been having a running "discussion" with one of the guys at the field I fly from about the new fuel lines on my plane. He claims all of the fittings ahead of the firewall MUST be steel for fire safety, not aluminum. He claims in the case of an engine compartment fire the aluminum fittings would melt and fuel would fed the fire. I point out that the major components of the carb are all aluminum as well as the gascolator and the spider, most of the primer parts .........
He claims I MUST replace all of the aluminum fittings with steel, which would cause galvanic corrosion in the aluminum carb and leak around the threads eventually. I'm getting a little tired of smiling and nodding my head at him to avoid an argument.

By the way, he has NO authority. Just a typical ramp know it all. I'm interested in your corrosion test. Anything to do with alcohol in fuel corroding the aluminum because of the absorbed water?

Hi Darryl,

I don't have a scrap one but I think Fresno airparts might. Check with him.

Hank,
Ya might ask him what about some of the -8 engines and the magnesium accy case? haha I think the aluminum hardware would be far from the front of my mind if I've got a fire up there.

Re: Piece of carb for corrosion test

Hank, easiest solution, go right along with him as if you are taking him seriously but don't change anything.

You pegged it on the test purpose.

Dave, I'll check with the guys at FAP. Thanks.

DC,

I tried calling Fresno with no luck recently??? Are they still around?

Re: Piece of carb for corrosion test

Don't know, haven't talked to them since summer last. I'll check.

Re: Piece of carb for corrosion test

Yes they are,(559) 237-4863. I just ordered some parts last month. They only take cash or checks no credit cards. Good folks!

Re: Piece of carb for corrosion test

I ordered accessory case & all accessory gaskets for an 0300 from them last week and got them monday.... the guy I talked to said he was looking forward to having two weeks off. They might be out for the holidays.

Navajo Accessories in San Antonio has multiple Stromburg carcasses in their stash of sellable stuff

Hmmm, I'm trying to scan my brain and think of a single aircraft that has ferrous fuel lines. I would tell him it's not required on a Taylorcraft because it has metal wing ribs.

Does this guy happen to have any connection to Ercoupes?

[Hank Jarrett]

Re: Piece of carb for corrosion test

Not that I know of. Unfortunately there are no Ercoupes on the field at SFQ. Too bad really, I like them.

Re: Piece of carb for corrosion test

OK, a word of explanation:

Ercoupes have the gascolator mounted directly to the side of the carburetor with an AN nipple and a 90 degree fitting. The original parts were aluminum, but, due to cracking, there is an AD that requires they be replaced with either brass or steel. No melting issues, though, and it only applies to the two pieces between the carb and gascolator.
