After a miserable Michigan Winter (one of the worst on record) I am back to work! Not a lot of time to work on it today, just enough to solve the mystery of the gasoline shooting out of the secondaries vent.
From my initial research, it had to be one of two things: bad/dirty needle/seat or leaky float. Either are fixed easily enough, but less to disassemble to replace the needle valve. So I pulled the assembly, cleaned and inspected it. It look as new as it did when I installed it when I rebuilt the carb, but you never know. I replaced it in the carb, turned on the fuel pump, and...fountain of gas.
Must be the float.
So I pulled the rear bowl (I used the reusable gaskets -- yes!), disassembled the float, replace it with the new one, reassembled everything, and...fountain of gas. CRAP!
Must be the needle valve. So I did a little looking online first. Maybe I missed something. Not a whole lot to the system to mess up. Apparently I used a different set of terms for my search today, because I round option #3 that hadn't been previously discussed: on some carbs, the secondary float needs to be plastic, not brass or it will hang on the metering block off plate. Really?
Back to the carb one more time. I pulled the float adjustment screw, and with a jewelers screwdriver I tried to move the float. It was wedged in place.
One more trip to the local speed shop, Diversified Creations, for a not-so-shiney new plastic float. Repeat step #2. Brass float out, plastic float in. The plastic float is well over 1/4" less deep than the brass float was. After reattaching the rear bowl I checked the float and it moved freely.
I turned the gas on, no fountain. Mission accomplished!
Next post will hopefully cover work on the new used doors I picked up...
