I am aware of the sites and books that advise you on which chokes and jets to fit to different levels of tune but obviously each engine is different, i see myself ending up buying loads of different jets etc and only needing a few? anyone know where i could borrow some from? I am fitting twin 45's weber to pinto with a fr32 kent cam, ported and 3 valve seat angles cut... standard bottom end balanced and 6 kg flywheel.

there is only one way to do this, rolling road..... go to some one who knows there stuff n most won't even charge for jets as they will keep the ones they take out...

anything else is guess work and won't work, (not at its best anyhow)
