The millionth what jeting to start with

[dufrain]

I am finishing my rebuild and need a starting point.

 

Aggressive dune port, second overbore.

Stock head,stock compression,

Toomey t-5 system

Stock carbs.Tors in the junk pile.

Stock timing plate but adjustable plate on order.

Pro flo adapter w/ K&n no lid

sea level. 80s-90s temperature here now.

 

I have stock needles and plenty of mains and pilots. I will be running 93 octane with 32-1 maxima 927

 

I would like to know a good point to start

air screws how many turns

what slot to put the clip on the needle

pilot and main

 

I hope thats enough info for some ballpark jetting suggestions. I looked through the jetting thread but couldnt find my exact setup.Thanx for help.

i would start with 330 mains, needle in the middle, 25 pilot, airscrews @ 1.5 turns from seated. get her warmmed up, and do a proper plug chop, then play with the needle if the mid throttle has issues, and airscrews to get the off-idle operation. less than 1 turn on airscrews, increase pilot 1 size. more than 2.5, go back down. syncing really helps it to run good, too.

Thanx alot for the advice. As long as I can get by with the 25 pilots I will be able to put it together tommorow and see how it does.Thanx
