I'm having the same problem on my Bing 54s.
Before you take them apart, find specs on where to set each adjustable component
when you are reassembling(for instance, how many turns in or out to set the
idle screw. Someone helped me adjust my carbs and it hasn't run right since.
The settings are out now, so using Pre-rebuild settings won't help.
Where can I obtain this information?? anyone??

My engine was running rough so I've discovered that one carb was not working
properly. So time to rebuild. Any tips? I do have a manual but it gives limited
detail. I've thought of sending them out but that is the wimpy and expensive
way out. Somebody told me that the real bush pilots I look up to can fix thier
own planes. haha

Dave:
I would call Bing at 800-309-2464 and ask them for help. I just ordered two
rebuild kits for my 912 UL, as well as the Bing tuning and parts manual.

I am curious about something. Do any of you who have a clutch in your
re-drive have a separate tach for your prop? Any chance of ever exceeding
the design rpm of the prop while in a power-off dive? Sounds like it might
be more difficult to induce that problem in a Fox, but perhaps something
some of the more slippery yank and bank types might have to be concerned
about?

Who was it that found some type of paint that would show fuel leakage. I
really would like to get some. I want to put it on critical components of
the fuel and turbo system.
Thanks

Please correct me if I am off here, but if the prop goes supersonic I
believe that is exceeding its design limit or at least its efficiency limit.
I cant imagine a prop that would not be designed to operate right up to that
point. There are some props that have a range of operation to be avoided
depending on the engine prop combination. The prop builder knows which as
this can cause fatigue and failure due to harmonics in a given range of
speed. Some props work better at a given speed and pitch combination than
others. Just a quick jab at a very complex and lengthy subject. The next
prop I get will be perfect until I find the next perfect prop. And yes the
NSI redrive uses a sprage type clutch. No prop tack but if you know your
engine rpm and reduction drive ratio there is a formula to figure out prop
tip speed, which is what I think you want to know and not prop rpm. I have
it some where.

That was me Rick,
My super dupper magic formula is "Krylon Rust Tough
Enamel, or RTA 9230 Cherry Red" from the hardware
store. Ha ha.
The stuff just happens to bubble up, or desolve away
with auto fuel. Don't know for sure about Avgas. It
formed a blister or bubble at two fuel seeps for me
where the welds weren't solid. Easy to find the leak
like that.
I am not sure about it handling much heat like on
engine parts though. But it should take any heat you
would let get at fuel related parts.
Be careful. It has Keytones in it so don't breath the
stuff.

I agree with Rick,
A lot depends upon what the designer built in for a
strength safety factor and for low pitch stops. As
you know, the lower the prop pitch is in a dive, the
faster it will spin. I don't know what the other
props have, but the NSI CAP prop has a low pitch stop
that should keep it from ever getting near the rpm
limit.
In fact, that prop turns a bit slow in normal use. I
notice a major increase in thrust going up from say
5200 engine rpm to 5500. It isn't just engine output.
Seems like better prop efficiency too.
If you are pushing overspeed on your prop, you will
also have a lot of drag to deal with. Enough you
shouldn't miss it.
