RE: OS 160 FX / Bisson Pitts / Perry VP-20 owners
Thanks PlagueWielder, that was helpful. I know that our needles won't be exact, but it's nice to know that your high end is less than one full turn out. Mine is at 3/4 turn. The only difference in setup seems to be the VP20 vs VP30, and they seem to be delivering close to the same amount of fuel (if the high end needle is any indication). I'm curious how many turns out your low end is. It is good to know that it is < 1mm gap when the carb is wide open. I'll check mine when I get home, but I recall the gap being a lot larger than that, perhaps even 2mm. I thought my low end was too rich and if my memory is correct, it is, based on your needle gap.
Thanks,
Gary
