Re: Terry Bowden still in busness ? or has the rain closed him down ?

All other accessories are for a C-85 including the M/S 10-4240-1 carb, which is odd as obviously it's feeding more airflow at a given rpm...whatever. It runs well and apparently not too lean so far as I can see.

Hi Gary. Your statement above ,on the Marvel carb, caught my eye, as I am about to make the upgrade and retire the stromberg.

Jim

That may be Jim...the lean behavior. It would seem a change to a larger nozzle would be required along with the increase in displacement with the stroker kit. It's not part of the STC so I'll leave that to an expert.

I don't have enough experience yet to tell and without a 4-point EGT can't directly measure the A/F ratio via exhaust temp. When I can I'll play with the mixture control to see how quickly it passes from full rich into a lean condition. I'd normally expect some rpm increase at cruise altitude (3-5K') if it's a bit rich. So far my flying has been limited to under 3000' and I'm running it full rich for break-in. If anything the exhaust is a bit dark but that may be due to new engine oil consumption until the rings seat.

After winter flying with a Stromberg in my PA-11 I soon got a Marvel with an accelerator pump and donated the Stromberg to the dumpster.

..donated the Stromberg to the dumpster.

Really? What a waste.

Really? What a waste.

Don't worry, I exaggerated as to its fate out of spite for the product. It was given to a mechanic that had a need for a replacement for his plane that never flew in cold temps.

But having one quit too many times was enough to convince me they were never designed with an Alaskan winter in mind.

Thank goodness! Well next time, send them to me! I could do with a few carcasses over here.

Has anyone had their Stromberg overhauled by the
Stromberg Specialist or any other reputable business?

Interesting post from j3 forum...

Default Re: Carburetor, Stromberg or Marvel?
So now I have to explain, first I'm a cheap bastard and I'm a float guy and that means that I'm a cheap SOB in search of the most power for the least amount of money and for many years I have been a Marvel carb only type of guy, at one time I owned a C90 Champ and a C90 Pa11 at the same time, the Champ had a Stromberg and the 11 had a MA3-SPA and both had seaplane props, I had time one day and took the Stromberg off of the Champ after I'd got the static RPM and installed the Marvel and hooked up the mixture control and did a static test, the Marvel was about 50 RPMs short of the Stromberg even with the Marvel leaned out but I didn't believe it because I'm a Marvel kind of guy so I switched back to the Stromberg sure that I had misread the RPM and redid the test, 3 times back and forth and the Stromberg won every time by about 50 RPMs, fast forward 2 years and I've got a J4 C85/0200 Mac 1b90 74x40 prop with another Stromberg on it and I'm still a Marvel guy so I'm sure that the Marvel off of my C90 Pa11 will give me more RPM so I switch them and guess what, after switching them back and forth a few times the Stromberg wins again, go figure, I always run a fairly flat prop and my Stromberg always runs smooth and even with a rapid throttle advance it never skips a beat, the Stromberg has a reputation for stumbling with fast throttle advance but I have never had it do that but that might be because the prop is flat and not loading the engine down, I run a Delrin needle and with the 4gram counter weight added to the float it doesn't leak, not a drop. Your milage might vary

Re: Terry Bowden still in busness ? or has the rain closed him down ?

Jim,

I had the opportunity to speak with, a couple of years ago, by phone the Stromberg guy in the Chicago area, Bob Kachergius. I do not doubt his knowledge of the carb as well as the possibility he has a huge stash of Stromberg parts. He also will advise that many Strombergs, due to manufacturing issues, will not allow the float to move the required amount. He has an FAA approved, (his statement), way of machining the carb body to allow the required movement.

The thing that turned me off was that he charges a LOT of money to work on a carb. I had mine done by KPS Airmotive and have not had to touch it since I installed it. Here is another thread about Strombergs and the guy you may be talking of, Bob Kachergius. http://vb.taylorcraft.org/showthread...omberg+rebuild

Thanks Marty. If the cost of rebuilding an old carb approaches that of a newer one I think I know which way to go. I am going to do some more research.

Thanks Marty. Carb specialist in my area said that a new Marvel would be about $1000.00.

Good info Jim. I specifically asked before doing the Stroker kit about fuel flow. Was told none was required per the STC (but was told it was a good question by your local shop Custom Aircraft Engines). There is a carb (4252) for the C-90 that probably has a different main jet/nozzle assy but then who's going to do the approval?

Surely by now hundreds of Don Swords and Aircraft Specialties' customers would have been made aware of the need for the carb change.

Edit: In 1974 I had a similar Taylorcraft (N29694) with a stock C-85 when I lived in Delta Junction, AK. It had a Marvel carb for either an O-200 or C-90, not the 85. Never ran well, ran too rich, needed constant observation, and had a flat spot. Might have been the venturi or jetting. Not sure. My current carb (4240) works very well so far.

If you'd prefer send me a private message and I'll not discuss it in a forum context.

Re: Terry Bowden still in busness ? or has the rain closed him down ?

I am interested in how anyone gets the Axle Sleeves from Grove or F Atlee Dodge. I too would like to put Grove or Cessna brakes on my BC12D. The Shinn setup
will not hold me for a runup. I have a C90 and a big prop. ANY HELP would be appreciated.

Call Grove aircraft in California ask to talk to Robby Grove and order them.

Re: Terry Bowden still in busness ? or has the rain closed him down ?

On 6/19/2015 I was given a price of $148.00 each from Grove for the sleeve and the Part number is 5058 ( This is the replacement axle sleeve for obsolete PN: 5045 Taylorcraft sleeve ) It has t be made to order.
