Great Post Ron.

I have talked with many a pilot who state a lot of the Myth's that are talked about on the posting I made. The thing about this. Here I am just showing up on the aviation seen a few years ago and now I am trying to show things like this to the old times whom have been doing this or working on things like this for years. With the attitudes of these folks lets just say...Who the yeck am I telling these people anything.

Attitudes like this are not good, Makes me wonder how they ever learned anything.

Got a Stromberg on my Fly Baby, been working fine. When I run 100LL, I pull the mixture out full while taxiing. If I forget to push it back in, the runup quickly points out that the Stromberg mixture control DOES work.

I've never used it in flight...most of my flying is done at 3000 MSL or lower. Have fiddled with it, verified, again, that it *does* work.

Only issue I have is the "Stromberg Drool"; a very slow drip from it. I put a pan down to protect the hangar floor. Sure, I should pull the carburetor apart, replace needle and seat, lap them, etc. But it works, now, and I'm loath to mess with it.

Though who knows. At the last condition inspection, the A&P had me sign a statement acknowledging he recommended I replace my 50-year-old mags. He'll probably add a line about the Stromberg next year. Eventually, I'll have a whole disclaimer list....

(Good A&P, though, just a bit skittish about liability).

I never could get my C-85 to run well on a Stromberg. Finally went with a Marvel-Schebler and am much happier. No stumbles, no rough-running rpm ranges, and much better fuel economy. I rarely fly above 3000 msl, too, but I've gone from 5-6 gph to 2-4 gph! No question, a Stromberg will suffice, I flew with one for years, but in my hands, it's no where near as good as an M-S.

Jeff, I've never had any real problems traceable to the Stromberg on my own C-85. But I do have an RPM range (about 1800 RPM) where things do seem shakier. I always assumed it was a prop issue (metal prop) but after reading your experience, I wonder if the Stromberg doesn't like that RPM....

An old-time EAA member gave me a box 'o Strombergs a few years back, maybe I'd better dig out a carb or two of the right model.
