Which ones do you have to trade? I have 35s, I'm currently at 55 actually looking for something larger.
Trying to overcome a bog/flutter on throttle tip-in, to make that transition smoother. 140 mains gets me spot-on for AFR at WOT (mid 12s) but as a test I tried 170 mains; AFR went too rich (of course, low 10s) but the tip-in bog/flutter went away. So I'm thinking I'd try larger accel pump jets.
What's your situation? I'm glad to trade but I'm a bit hesitant to give up what I have until I verify the resolution.
I have modified 35s in there now. I was going down the road of larger and larger pump jets until I switched from setting the float height with the top "upside down" to having the top "hang vertical" and the float just barely resting on the spring for the inlet valve.
I'm pretty sure I have a new set of .60 pump jets if you want to try them. We could just mail each other the jets for each other to try. I also have a large selection of jets you can try, but most are reamed and not purchased. I ream and measure...
What are the specs on the carbs and motor?
Here is my current setup:
40 Dellorto
36 venturi
152 main
200 air
60 idle
35 pump (modified)
5-12 floats, vertical
250 inlet valve
