TR3 engine starts and runs, then flutters and, now, dies. I've been through
the fuel system completely, short of a magnet in the fuel tank, which I might
try. Completely disassembled the carbs again today. Jets centered, float
bowls have no gas in them, float valves perfectly adjusted, and the puff test
shows they stop flow as they should. Mixture and idle is right. Not to
mention I tried a complete swap out of these carbs (rebuilt by Quantum
Mechanics some years back).
I've tracked wiring through the system. I thought a partial open (broken
wires) at the lighting switch where it feeds the ignition switch would fix it.
Didn't. Replaced the 60 year old ignition switch. Didn't fix it. Double
checked the fuse holder for solid and clean connections. Not the issue. When
it does run, the voltmeter (not ammeter) shows just the 12 volts from the
battery, and not a charge. White wire from the fuse to the coil tests no short
to ground, and bypassing it with another connecting wire doesn't cure the
problem either.

Symptoms seem similar to a problem we had in my wife's TR6. Do you have a spare
coil to swap in? That was her problem. Previous owner had an engine rebuild and
the rebuilder put back in a 40+ year old coil. Replacement coil and tight
connections were an easy fix.
