Accelerator pump cam selection methanol carb
Thanks Bob. I had a look at this carb tonight and it's all up the sh#t the way it was "set -up". It has big pumps with the crazy brown cams then to make up for it small 25 squirters. Put a fuel line and pump on it and the floats are way high so at 6 psi there is fuel dribbling through the boosters. I ran a carb in the 1980's and spent ages sorting the pumps out when I went to a converter type trans. I figured there were boats with prostock engines that left from idle so I applied a bit of that thinking and all good.
I'll spend a bit of time with this and most likely chuck the brown cams in the trash replace them with some that don't feel like they want to break my throttle cable adjusted to start their travel just on start line rpm and start with some 34 squirters. I have 24 deg at idle and an additional 10 degrees in my maggie. I was just looking for a quick bolt it on and all's good deal with this carb as it's only a short term deal but as usual I'll put in the time and get it sorted and it will just have to be a few more weeks until I'm ready to rock and roll.
