For several years now I have had a recurring issue with the 964 S Carter YF on my 216. It would flood out. I had recently come to the conclusion that the accelerator pump was being destroyed and then clogging things up. That may have been the issue for a while but I have found a new possible suspect.

I replaced a short gas line going to the inline filter that I had placed between the tank and the fuel pump. Once done, the flooding returned. I found little black specs in the float bowl and the needle and seat. I also have the screw in filter at the gas inlet connection going into the carb.

Yes I was using new /modern gas line, a new paper in line filter, a glass bowl fuel pump, and real non ethanol gas at this point. In fact I had just dumped in 5 gallons in the tank. The tank is also new.

My point is no matter where you have rubber, ethanol will find it and cause problems. The rubber exposure on mine was no more the about two inches.

My question is what type filters are you guys using, and where are they placed? I have a pre pump and a pre carb in addition to the fuel pump screen.

Is there a recommended micron number for the filters?

Thanks for any input.
