Harry Bieker Engineering - Results - IDS

[1968SWTs]

Before and after (5 months) photos.
Harry ALWAYS answers his phone. Nicest guy in the world. Takes a while. No flaky behavior at all , just getting up there in age and has been ill lately.

Machine work is great - no more vacuum leaks!

Attached before and after.

Original estimate was $950, but cost ended up as $1200 including insured shipping.







Now I need to resell the temporary carbs, which I thought were going to be permanent. I thought I would never see the IDS's again, but was happily surprised to see the UPS box.

I was the buyer of these:
FS Pair of Weber Carburetors and Manifold

Damn, now I know what I want for Christmas. Very nice.

I bought a gorgeous set of Solexes from him a few years back. He knows his stuff.

Get rid of those fuel hose clamps and install "Norma" brand band-style ones; they won't tear into the hose (see pic of my 2.2 "E").

Also, don't forget to safety wire the float retainer screws.

Beautiful work by Bieker. Also don't forget to put some safety wire on the venturi pinch screws. Thin venturis are easy to deform if you overtighten the screw. Safety wire allows you to not worry about overtightening them.

Get some PMO fuel bars and you can ditch the pesky banjos, hose and clamps altogether!

I like the "Norma" style of clamps and prefer them but on every single aircraft I've ever flown (including factory new) I've yet to see anything but the traditional clamp like the one pictured above. Certainly aircraft applications are more critical than what you would find on an automobile.

Yeah, the old man is good. The kid.....not so good.....

Don't know about planes, but at the shop we used to call the clamps pictured in the OP "rip and tear" clamps. When we found them we replaced them, and the hose they were clamped with. Carb applications are low pressure compared to FI systems, and we found "r & t" clamps at fuel pumps, gas tanks, and in engine compartments. I hope that our efforts saved at least one car, its occupants, and those who might have been affected by a car fire.

The following is an interesting piece;

In addition, I think that the "r & t" clamps have been re-designed so that when they are tightened they don't grab and tear the hose. Perhaps this is what's being used in aircraft applications?

[KNS]

On the helicopters I fly (around 1.5 mil new), you can find at least a couple dozen of the traditional style hose clamps. On everything from the oil, fuel and transmission fluid lines.

Interestingly, I just looked up the style used on aircraft, the "Breeze" brand which, when I did a search, falls under the "Norma Group" of clamping products.

I agree the Norma clamps "appear" to be a superior clamp.

Edit: Thinking about it, I believe some of the applications have an exterior hose sheathed around an inner line. I don't believe they are all like that, I'll have to look again. Still, you don't often see the manufacturers skimping on the critical stuff.

Amen on the your opinion of "The kid".
