Actually I think I had more gas spurting out over the engine than getting into the
oil but I will probably change it just in case. I;m pleased that I actually acted quickly enough to reduce damages. Opening the hood to that picture of flames was not something I ever want to see again.
I have a Fram filter back at the tank but no other filters. Except those little cylinders in the carbs. I think they are there to collect small rocks. I might add the 10 micron in line as suggested and I'm going to replace the fuel pressure gauge. I want to make sure I don't have too much and what is there now is a cheap Jegs liquid filled. It was set to a little under 3#. Also going to very carefully recheck timing. As suggested that may help with the boiling issue. I think I need to address that as much as the line debris.That's why I was asking about the success with spacers. Thanks for all the input. Jon
