Linkert bomb sight

[kenny]

I have a M35 lnkert carburaetor for a stock 74 knucklehead engine that has been converted into a sleeper carb set up and my question is at this point is there any more performance gain using the bomb sight ventura.?I will put this carb to use soon.Thanks all you linkert fans.

Kenny,

I do a lot of testing analysis and data collection. I have never been presented the opportunity to analyze one of those Linkert set up's in my test cell.
For that reason I am unable to share pros or cons in this subject.

I would be very interested in seeing any information/data accumulated by other members.
I'm always open minded and looking to learn the pros and cons, because everything has both...

Your M35, Kenny,

Accepts virtually none of the original M53 'bombsight' hardware.

Perhaps you are considering a modern 'hybrid' replacement venturi, in which case all bets are off!

The factory figured out the bombsite wasn't a great top end performer. Most later racing carbs did not use it and the updated KH carbs did away with it. The low speed and accelearation gains were negated by loss of top end. The venturi in the MR3 and MR4 was stamped brass, the M53 venturi was pot metal like other types.

OK, I'll bite, Kenny!

What's a "sleeper" carb?

I know your response is just "click bait" as most of yours are but just for fun this came off another forum regarding something completely different but applies well.

" An example of a sleeper is something that look plane ubiquitous or benign, low performance but has been changed or modified for increased performance without visually being changed outwardly."

If its 'click bait', Robbie,

Shouldn't I get something for it?

If you are paid to rag, it explains a lot,.

Hello Tom Cotten. I have a M35 linkert that has all the m74 linkert internals. Im thinking that this M35 carb does not use the fixed jets. Guess the m-35 carb is named a sleeper carb that has the internals of a m-74. Kenny.

Please be aware, Kenny,

There was at least two different M74s (different bodies, HS needles, and main jets), and perhaps four different M74Bs, so you really haven't told us much.

And just arbitrarily swapping hardware can have mixed results, of course; Much more depends upon the condition and fit of the hardware, such as a larger venturi does little good if it doesn't fit the bore; We must assume the carbs were ideal for the machines when fresh, but everybody wants a little more!

Beyond complete reconditioning, traditional hidden tricks include things like shaved shafts, knife-edged choke disk, both discs soldered in, and the bowl hogged out for more reserve volume. None of these can be easily observed, but have positive results. (Many other 'hacks' show up in the fossil record, but we have no idea how they performed.)
