Holley/Demon Carb stumble

Before the original Holley HP950 existed, modifying 750 Holleys to use 850 baseplates was a pretty popular mod in some oval track series.
I did a few of them myself.
When doing this mod, as I said earlier...... there was a mismatch in placement of the idle discharge holes between the main body and baseplate.
If you didn’t correct it, the idle discharge ports in the baseplate were blocked off completely.
The carb effectively has no idle circuit in that situation.
So the blades have to be opened up enough to either expose the transfer slots enough to run, or even farther to get the main circuit activated.
A little tweak to “connect the dots” was all that was required to get the idle circuit working normally again.

The point being........ even if the discharge holes in the Demon body and the PF baseplate don’t line up....... it should be fairly easily correctable.

One of my friends decided to do the 850 baseplate upgrade on his 750DP.
He had overlooked that part of the mod, so of course the motor wouldn’t idle......at all.
Letting off the gas was like turning the key off.

He called asking advice....... I knew exactly what the issue was but wanted him to find it himself, so I kept telling him to “follow the path of the fuel”.
He never did figure it out, and was pretty convinced I wasn’t sure how to fix it myself.
So, I told him to drop it off with me, I’d fix it..... without telling him how to do it........ and if he bolted it back on and it worked, he’d pay me $50.
The $50 wasn’t really for the labor so much as doubting me :soapbox:

Yes...... I got the $50.
