[Tigers] Carb Fire Continued

[Ron Fraser]

    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?
