[Tigers] Carb Fire Continued

[awtiger at cox.net]

Stu:

There is a possibility that there may have been small piece of trash that got lodged in the needle valve that kept it from shutting off the flow of fuel from the pump.  This happened to my father-in-law on his '55 Ford pickup that he built.  He installed a 302 in it with an Autolite 2100 and an electric fuel pump.  As we were working on it one afternoon, fuel came pouring out of the weep hole in the top of the carb and running down all over the intake.  Luckily, we caught it before there were flames.  When we started diassembling things, we found some trash lodged in the needle and seat.  We thoroughly cleaned that assembly and then reinstalled it.  There have been no problems since.  It would be interesting to cut open your fuel filter to see if it contained any foreign material.

Keep us posted,
