Well...
I am definitely in the "has a history" camp.
When I bought my Tiger in 1971 I definitely had the problem.
In my case it was cold starts. Every once in a while (well frequently)
but intermittently I would turn on the pump in the morning and hear
the familiar plink-plink sound... and hear the plink-plink sound...
and hear the... well you get the idea. Open hood and see the intake
manifold all wet and puddled. It got so bad I just drove it that way,
fortunately it never caught fire.. surprisingly.. dumb kid!
I tried checking everything and several new inlet valves but it still
did it occasionally. I didn't get it finally fixed until 1973 when I
bought a Holley that is still on the car. Now of course Holley's have
their own fuel leak problems but never a stuck inlet valve...

Subject: [Tigers] Carb Fire Continued
Michael King thinks there's a history of the stock carbs lighting things up
on hot restarts. Does anyone else have any history?
Does anyone know what the mechanism might be? I know the accelerator pump
is OK, nothing dripping there. The only other logical explanation is fuel
being forced out the bowl vent. I'll look for traces when I take the
photos tonight. Could the float valve works have occasional issues? A
sinking float? Could fuel be boiling from the heat soak when its shut
off? Or when fuel hits the hot bowl when the pump starts? Any other
theories?
