Well...when I removed the carbs and drained them, nothing came out of #3 float bowl...aha!, I said...I took off the floatbowl covers and looked carefully at the pictures and description for setting the height...I made a measurement device like the ones online from a Raisin Bran box...not adjustable, but the height measurement I made sure was 7.5mm (see pict)...spent a long time being sure each float was set correctly...installed the Randakk float bowl gaskets, reused the large intake o-rings (new, from the week before...thank you, Cornpone!), replaced the o-rings on the secondary air supply tubes, made sure the vacuum lines were sealing...she sounded great when I started her up...went for a test ride just now...still backfiring through exhaust under acceleration...adjusted the choke cable so that it was not lightly on...then I tried adjusting the pilot screws...no matter what the setting on #1 and #3, there was no effect on the idle speed...#2 and #4 adjustment had the expected effects...all the screws were set at 2 turns out initially...I had not fooled with them before...didn't take them out for the carb cleaning...sounds like I should have...now, when sitting at idle and I crank on the throttle, she will sometimes backfire slightly or slightly hesitate right at the beginning of throttle opening...multiple crankings on the throttle sometimes produces a loud backfire. Should I remove the pilot screws on #1 and #3 and squirt in some carb cleaner? or what?
