Any luck so far, Theorist?
I actually enjoyed this topic
Thank you.
I had to leave town before making much more progress. I'm hoping I'll remember enough to be able to reassemble the carburetor correctly when I get back. At least I left one in tact, so if I run into trouble I have the unopened one as a guide.
For the that broken fuel line for the accelerator circuit between the float bowls, I found I was able to remove the metal insert from the rubber and insert in in new rubber fuel line.
While I'm away I've given some more thought to what fuel pump at petcock to order. Does anyone know how much fuel pressure or flow rate the electric fuel pump on the early GT250's or the vacuum driven fuel pump was supposed to provide? I vaguely remember reading that the very early GT250's used a manual petcock valve, a fuel filter, and an electric fuel pump. I would be very nice to know what the specs were for that electric fuel pump. I'd rather get the pump right and not have to bother with a pressure regulator and measuring the pressure at different loads and engine speeds. Would anyone like to recommend particular pumps they've used successfully? With many negative reviews of leaking and failing inexpensive fuel pumps online, a reliable new vacuum pump has some appeal even if it won't provide the ultimate performance I'd like at wide open throttle, especially with the air filter desnorkeled and little vacuum at WOT.
