I don't know of any history of the Autolite carb being a fire hazard.
We are working with an open fuel system on the Tiger instead of the closed
systems on newer vehicles so we need to do a little more maintenance.
I would look for these:
Too much fuel pressure from fuel pump
stuck float valve
Sinking float
Fuel line fitting leaking
Bad carb gasket
Cracked carb fuel bowl
I would think that if you turned the fuel pump ON you will see a fuel leak
somewhere.
Just be careful when you try that - fuel spray can hurt.

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?
