What Max said it's correct... And for most Evo's and Shovels (Stock) a 70 main and a.0295 intermarriage is the starting point.. 1.5 turns out from lightly seated is the go to for determining the proper intermediate jet size.. A good starting point for the accelerator pump is 2 full turns out from seated.. And the accelerator pump does not help in transitioning from intermediate to main jet... It supply's fuel for the abrupt opening of the throttle plate to keep the engine from coughing out the carb.. Some call it Sneezing... God bless you...

Also to the original poster.. sometimes it make a huge difference to let us know year, make and model and if you have any motor upgrades... Anything less than that makes it a crap shoot...
