howdy,

my dad (joe mccauley) has already extensively posted pictures of our allison and stinger, ill cut straight to the point


i want to tune the stinger, and ive already made one air horn for the carbs. how many sizes up should i go with the high speed jets and is there some formula for calculating that, you know, taking into account the length of the air horn etc etc...

know i need to rich it up, and i understand the principle of it all, i just want to be careful and not have a nice little rattling sound of the rod clanking around in the crankcase..
