Thermoquad worth it - or no?

Bobby, the actual problem comes from timing of the rods coming up. The "Egg" or "Lobe" of the cam within the carb in the base plate can not exactly be changed out for a more aggressive ramp speed. Though it is pretty good as is, a bigger cam and the resulting change parameters are hard to predict (For me at least) On just how the engine wants the fuel curve to run. Since we know each engine is different, the complexity and combination probabilities are near endless.

the center screw for adjusting the rod height for lowering the rods into the jets or raising them changes the timing of fuel enrichment a little. Since the rod is deeper in the jet or not so deep in the jet. The time it takes to raise them is likewise shortened or lengthened.

Unlike a Holley, this cam is fixed, there are no replacement or swap cams. So, it kind of happens the same time every time. Only the delay of lowering or raising the rods for a quicker enrichment is possible.

Demonsizzler can ad adjustable air bleeds.this I have not looked into myself and do not know how he does it. I guess some thinking about it and time with a few carbs, I could figure it out. Not likely going to happen with me though. Not enuff time on my hands to do it. Also need a few things to experiment.

Adjusting the fuel curve on a TQ is a lot harder vs a Holley.

And this is a spot where most people throw in the towel on a TQ. I also do not blame them either.

Main jets that sit in the well (Primaries) are hard to come by. I bend AFB rods 3/4 inch's smaller to work as TQ rods. IF I am actually lucky enuff to get a TQ apart and I really mean apart, I can use a tap and re-do the main jet spot for use with Holley Jets.

Getting the cap under the jet off and still be able to re-use it is the golden trick. If it doesn't fall off to begin with, it's almost a 100% guarantee it will break and then your screwed, left with a door stop instead of a carb.

If they both fall off first, I'll tap the plastic body jet insert.

Pay close attention to jet heights.
