Symptoms sound very familiar.
Verify that your intake manifold is seated squarely on the head. It is very
easy to have a gap at the bottom that would prevent vacuum. It is also very
difficult to see from the top and everything will look fine.
I was stumped by this once, and had the same thing happen again years later on
a head gasket replacement, and after 10 minutes, identified the same problem.
If it happened to me 2 out of 8 times I've had the manifolds off of a TR3,
either I'm an idiot, or it's a common problem. Other than that, check vacuum
and make sure you have it.

Subject: [TR] Recalcitrant TR3B Engine
List,
I have reached the point in the restoration of TR-3B TS68368 where the engine
should run, but I cannot get it started. After engine rebuild, including new
pistons and liners, I have verified following:
1. Fuel:
a. Rebuilt cards
b. Fuel supply to carbs good
c. Float bowls full
d. Carb needle settings - tried 10 to 13 flats 2. Valve train
a. Verified valve timing - # 1 cylinder valves both closed at TDC
b. Verified valve gaps set to .012
3. Ignition
a. Timing verified as correct with visual check of rotor position at #1
cylinder TDC.
b. Plugs getting spark.
c. Verified firing order.
d. Replaced electronic ignition with points & condenser
e. Point gap set to .013.
f. Engine fires strongly when starter fluid sprayed into carbs which
indicates that the ignition system is working properly.
What have I missed? Incidentially, this block also has "TR 3" painted on the
left side in orange. I elected not to paint the block to preserve this
original marking.
TIA,
John W
