C85 Conversion Complete!

My valve is owner produced parts, I gave up on the STC...feds were too difficult

Don't blame you one bit Tim!! People don't realize what all it takes, and how long. No matter how many hoops you jump through, they seem to come up with one more!

Owner produced parts...that's what I meant, not STC!

Tim, you are right about the drip. But I personally prefer the steel needle, so there is never an issue with aromatic fuels.
I always turn the fuel off of course. As you know it's good practice to exercise the fuel shut-off system in any aircraft. But the Stromberg does need periodic maintenance/overhaul to check for corrosion in the bowl.

I once did an annual on an Experimental Starduster here in the UK, and I tried to operate the fuel-shut off valve. It was solid, so I asked the owner what he would do in case of an engine fuel-fed fire?
He said "turn the fuel off!"
When I showed him how that wouldn't work, he walked away. I ended up replacing it, with a NOS valve (essentially the same fuel valve you now sell under STC). The aircraft got wrecked later, but not for fuel issues.

For me it was that perpetual drip because the steel needle and brass seat never seemed to be perfectly sealed...I also broke 2 discharge nozzles off inside the carb because of corrosion.

I overhaul Strombergs here for the UK market (experimental). They are not rocket science. There are some secrets to prevent gasket leaks, but I keep those to myself for obvious reasons, as does Mr Stromberg Man in the USA. (!)

One day I'll fit a MS carb to my C-85 Taylorcraft in the UK, when I can get a core (I have the overhaul kit, mixture cable etc)

Thanks, Stu. Got it! I’ll look at the two Strombergs, and maybe take a peek Inside, then make a decision. ......

Cheers,

What is the core charge in addition to the $982.80 for the Marvel/Tempest? Suppose they will give me a deal on two of them? I've got two Strombergs.............

Cheers,

Jon

I'm not totally sure what you are asking, but when I bought my Marvel, the cost outright was $1,385. They gave a $600 core charge which came off this price for a marvel core, or would give a $300 core charge for a stromberg. My understanding was the stromberg core was more of a courtesy as I was told they just went and sat on a shelf. So net with a Marvel core was $785 and with a stromberg core was $1,085. Not sure if that helps.

[astjp2]

For what carb? They list the core on spruce from what i remember it is a foot note

Dual impulse slicks.

I am considering the same upgrade , but with a battery starter and no alternator.
what king of mags did you use and how was the fit. If you could send a picture that would be great. Where are you located at?

We have a Pitts S1S at my airfield that used to have battery starter, no alternator (or generator) for weight reduction.
It makes sense...you have the advantage of battery start, without the complexity & weight of alternators, voltage regulators etc.

Just one impulse mag, any brand, makes the whole process easier.

Plus, an S1S is easy to hand-swing if the battery gets cold, or flat.

I went with Bendix mags. There are a number of pictures under the thread on carb ice continued that I posted recently or let me know if you want something else. I have a spreadsheet of everything that went on it along with the cost. PM me if you would like me to send it.

That is one nice looking T-craft, I did the same conversion but added the starter after a near miss propping on ski's.
i think it makes a great plane even better.
Are those 8.5x6 tires?
Did you happen to note the oil temperature delta to ambient?

Thanks, I appreciate it. The C85 makes it so much more fun, and it was a lot of fun to begin with. Yes, they are the Dresser 22" 8.50s. I really like them and they have held up well so far.

I did not make not of the oil temp to ambient. I have noticed that the oil temp is coming up a little higher than the 65 which I like, my 65 barely ever warmed up in the winter.
