OK, XPAG experts, I need your advice on a seemly fuel-starvation issue while accelerating and shifting to higher gears ...

Details: TD #6961 with original engine. Just re-built cylinder head, new mild Crane cam, Pertronix ignitor, 3-year old Moss supercharger with single H4 carb. Engine ran GREAT until I re-torqued the cylinder head, reset the valve lash from .018-.020 down to .015-.016 due to unacceptable valve clatter (the .018-.020 is the recommended setting with the Crane cam). I also removed the carb suction dome and piston for their annual wipe-down as the piston will start to stick after a few months. Very careful to not touch needle, no sign of rubbing on any of the carb parts. New fuel filter and fresh premium fuel.

Now on a cold start (right away and smooth idle), the engine stalls whilst shifting gears from 1-2, 2-3. Nothing happens when pressing the go-faster pedal until I re-close the throttle then slowly open it again. Problem can be avoided by keeping the throttle open while shifting gears or pulling the choke out again. Problem goes away once the engine is at operating temperature.

I've triple-checked the carb suction piston/dome/spring/plunger for correct and complete assembly, jet assembly centered per drop-click test. Timing is spot-on and mixture set to mid-transition from yellow (rich) to blue with the Color-Tune see-through spark plug kit. The fuel pump is an aftermarket Facat brand electric pump which seems to be operating normally. The Moss supercharger setup features a single new H4 SU carb with no vacuum bleeds/ports.

Any suggestions?? Problem did not start until I re-torqued the cylinder head and cleaned the carb.

Reset the valve clearances to the specified values and live with the clatter, you are strangling it.

Reset the valve lash to .018. No change to engine stall with snap acceleration issue. :-(
Since the engine runs well at highway rpms and accelerates nicely (for a TD), I'm thinking fuel pressure/volume from a dying electric aftermarket fuel pump is not the cause. Idle rpm set at 1200. Any ideas?

I assume you are using the choke when it's cold? What do the plugs look like?

All I can add is to check for an induction air leak, that the fuel level in the float bowl is correct and that the fuel inlet valve is not sticky.

Woo-hoo! Problem found. 'Tis amazing what havoc a teeny tiny sliver of mis-placed gasket material can cause. After a deep dive into SU design and operating theory, I dismantled the carb one more time looking for anything that would dump the low pressure above the suction piston. I found a really tiny sliver of cork gasket material had "flowed" from the carb face-air cleaner plate and was barely in the mating surface between the carb base and the suction chamber dome. Although smashed very flat by previous re-assemblies, that was enough to mess with the pressure differentials.

Removed the material and I'm now once again out there drag-racing the motor homes and RVs clogging up the Oregon Coast Highway. Not to mention I now have the cleanest SU carb in the Western Hemisphere! Life is good ... smileys with beer

Installing the Moss interior kit! Not too bad but quite a bit of work!

Very nice.
I used the Moss interior kit in red in my TC back over 30 years ago and it was easy and looked great......I'm sure your finished job will be the same.

Make sure you feed the leather surfaces well and often, Mine have not fared very well -- 14 years of very light use.

Popped for a tonneau cover for the TC. A little spendy for an old man living on Social Security and eating cat food to survive, but a very worthwhile investment.
