I haven’t run one of those on anything in ages.
The way I remember them is....... they just weren’t anything special.
Some other stuff I tried worked a little better.
So, based on those experiences, if I’m buying a carb....... I’m going to buy something that’s “hopefully” a little better.
But that really has no bearing on how good one would work on your engine......especially if you already own it.
If you own one, just try it.
A couple years ago I had a motor on the dyno and the owner had brought several “fancy” built from scratch carbs to try on it.
All were the new type bodies, one had the billet 1.600 x 1.750 main body outfitted with some special annular boosters, all had billet metering blocks, etc.
None of them had great fuel curves, and the balance between part throttle and wot was not very good either.
I had brought my dyno mule built-from-scratch HP950....... “just in case”.
It was obvious it was going to take way way more time than we had to even get one or two of them really dialed in........ so we mildly tweaked one that was “closer” than the others to see about getting a number from the motor.
After some playing with the timing and spacers, it put up a pretty decent number.
When we were basically done for the day, I put my HP950 on, which is really nothing special in the HP making dept.......using the same spacer and timing we were running with the other carb....... and it had the best balance between part throttle and wot....... had decent A/F ratios without needing giant jets in it(which all the other carbs needed), and it made slightly more power than any of the others....... despite being the smallest one tested.
That’s just a long story to say....... you don’t know good any of them work without trying them.
