Carb is a Mighty Demon 750 with annular boosters. About the Jets, I'm planning start with 72 in primary and 84 in secundary.

SQUIRTER: 0.031
IFR: 0.038
IDLE AIR BLEEDS: 0.070
HIGH BLEDS: 0.033
EMULSION HOLES: 3
EMULSION HOLE DIAM: 0.031


The last 750 t-rams I did ended up as follows but your tune may vary;

jets 72-83
idle bleeds .068
high bleeds .029
kills .027
pvcr's .061
ifr's .031 lowered
t-slots .085
squirters .028-.031 pink cams
angle channels .140
needle n seats.120 6 psi max
emulsion .026 in #1 and #3 middle plugged

very little t-slot exposed on primary and secondary otherwise wouldn't idle but less is sometimes better........

Hope this helps you out.......... thumbs I'd get a better fuel pump if it was me............ beer

Mind you these were down leg boosters and you MAY need less jet.........Get a wide band if you don't have one already and tuning will come way faster......... thumbs


Dom, I really appreciate all your knowledge that you shared with me. Thank you!

I still need buy some parts to fine tune on carbs like bleeds, squirters and needles... But I will do.. up

About wide band , yes I've one with datalogger, amazing resource! thumbs


Anytime and v floats will help a lot........ thumbs


I forgot to tell you one important thing about fuel. Here in Brazil we've around 30% of ethanol in gasoline. This percentage of ethanol could change some configurations that you sent me ok?
