I'm interested in hearing how you've set up the carb, and what you're seeing w/ the fuel curve issues you mentioned. work


I made a few shake down runs at the local 1/8 mile track and the wide band skipped around by 3/4 of a point or so. My 1.375/1.68 carb was very steady,and the 1.375/1.75 carb was pretty behaved too. All these carbs have 3310 primary blocks with 2 .027 e holes and 26 to 28 HSAB. Despite the 1.45 carb's erratic fuel curve, it still managed to tie the best ET and generate the best MPH at the local 1/8 track in worse air. I added a third .027 e hole to a set of scrap 3310 blocks, and will also try bumping up to the supplied .032 HSAB and see what happens at the 1/4 mile track Friday.


I love this stuff and you SHOULD see it dip rich down low a tad then trend lean up top with the .032 hi bleeds............I say SHOULD......... biggrin Lookin forward to your results.........

Made to the track. Wind was blowing pretty good so the powers that be decided to run 1/8 mile. LAME. Anyway I tried the 1.45 carb with the .032 HSAB for the first few runs, then swithed out for .027 on my last pass. The AFR was rock solid stable with the .032 and varied about half a point with the .027. MPH fell off a few hundredths with the .027. This was with the untouched 3310 metering blocks. Main jets are 78/86, AFR was 12.9-13.0. Didn't seem to run rich at the bottom of the gears with the .032 HSAB. All in all I'd say if the car picked up anything it wasn't enough to notice, but a fun tuning/learning experience none the less. More flogging is necessary sawzall
