The drilling of a 1/8 hole above the throttle shaft in the center next to but not touching the shaft on most racing carbs is already done for you! This allows you to get the air needed to idle at a higher RPM that is needed with out getting off the idle circuit !!!------- Doing this along with running a vacuum advance to have higher timing at idle keeps it crisp and clean when running larger jets than most can using a power valve! The advantage is only there if loading up in the turns or at idle but in some cases it allows to go leaner on top end for a sudden burst of wickedness! The new found torque off the turn may surprise you to the point of unlocking your timing weights to be able to hook up again! Blocking off the power valve and getting it right has given us an edge that some thought was nitrous! Getting there is a bit of a gamble so go big and back down in the jetting or slowly up the timing process! Running on the edge of lean provides both torque and horses! This also requires more supervision down to air temps and how much oil is on the breather filters (by the draw factors) controled by reading the oil left on the spark plug threads!

Getting off the corner with high torque is a bit harder with all the horses harnessed! Clean and crisp gives the quickness needed but what to do with all those horses??? Delayed execution is the best way I have found in putting them back slowly and never unhooking them to start with! Its easy if staying crisp! No loss in gaining usage!!!

A lot of tune in foresight of engine design but the after effects have to match the tune as well to promote the transfer of power! A few jet sizes in conjunction with timing and temp changes can do wonders for most any engine to boost it up a bit more by flow power in increased vacuum producing more usable low end torque!!!

Too low of a idle--- can create too much back drag ( A false sense of tight or looseness instantly) when lifting and bind or hold a other-wise free motion in your set-up! This to diminishes the corner speeds greatly not to mention the amount of vacuum built to stretch rods or rod bolts when lifting with too much blockage of the intake! These effects are mostly with use of lower gear set-ups! If running a j-bar, you may be able to lower to free it even more or raise it more if needed just by changing Idle speed! If using this drag against shocks and spring preloads or chassis adjustments that has to be stronger to handle the sudden change, that too can be effected! My right front is 200 lbs. lower in preload with a stronger spring and 3-3 shock to allow for a easy nosing process with high idle in place! A much faster reaction to planting the right rear without chunking chassis' weight or binding the frontend down! A trick of the trade in faster, cleaner corner speeds with smoother set-ups! As simple as upping the Idle speed with forethought!!!
