Shims are utilized for fine tuning. If the secondary opens at the right RPM, but bypasses too much fuel, it’s flow back to the tank can be restricted by putting a jet in it. Replacing a thick shim with an .080” jet is usually a good starting point. If installing a jet be sure there is a jet sealing o-ring. Note: the jet sealing o-ring is equivalent to .060” of shim. SECONDARY BYPASS VALVES SHIMS FOR 6 AN JET CANS #3076 high-flow 6 AN brass valve Troubleshooting First follow all steps in “System Troubleshooting,” Pages #106-107. 1) Check to be sure that the poppet seals in the body. A small amount of dirt can cause the poppet to stick. Thoroughly clean the valve and connecting hose assembly. 2) If adjusting the secondary valve doesn’t seem to do anything, make sure the barrel valve spool has a bypass port (see Page #104) and that the secondary valve is installed correctly. 3) Adjustments to the secondary valve should not affect wide open fuel mixture; if they do: A) Check to make sure the spool is indexed correctly in the barrel valve. B) Check the fit of the spool to the barrel valve block. Approx. clearance is one-half of a thousandth of an inch. Too loose of a fit can cause fuel to leak out through the secondary port at wide open throttle. Test the fit with a leak down meter, 1% or less is preferred at WOT. © 2017 The secondary bypass is used to tailor part throttle fuel rate ONLY ; it has no affect on wide open throttle metering. CAUTION - Using a spring that is too light, especially on a supercharged or turbocharged application may cause a backfire through the blower/turbo or into the plenum, causing damage. #3010 #3519 #3522 #3043 #3535 #3521 3034 Shim kit, includes: 1- .183" thick shim and 6- .030" thick shims 3040 Shim, .183" thick, brass 3042 Shim, .020" thick, brass 3043 Shim, .030" thick, brass 3303 Spring kit, for Kinsler and Hilborn 6 AN jet can, consists of: .016", .018", .019", .021", .024" 3304 Spring kit, for Kinsler and Hilborn 6 AN jet can, consists of: .028", .032", .036", .039", .042" 3316 Spring: .016" wire diameter 3317 Spring: .017" wire diameter 3318 Spring: .018" wire diameter 3319 Spring: .019" wire diameter 3321 Spring: .021" wire diameter 3324 Spring: .024" wire diameter 3328 Spring: .028" wire diameter 3332 Spring: .032" wire diameter 3336 Spring: .036" wire diameter 3339 Spring: .039" wire diameter 3342 Spring: .042" wire diameter #3030 secondary bypass valve - CONTINUED -
