Take the jet out of the main bypass and replace it with one thick shim, .183” thick, supplied in installation kit. The main bypass will now be utilized only to keep pressure in the system for starting and idle with no jet in it. If the jets are installed properly in the valve, the richest jet will be obtained when the knob pointer is straight to the right (aligned with the outlet; see step #1 above), and the next leanest jet will be obtained by rotating the knob counterclockwise one position. © 2017 IF YOU WOULD NEED TO RUN A .100” OR LARGER MAIN JET IN THE JSV, WE STRONGLY ENCOURAGE YOU TO USE THE RANGE JET VALVE SYSTEM (see PAGE #83). JETS LARGER THAN .100” IN- SIDE THE JSV WILL NOT FLOW EXACTLY AS THEY SHOULD. CAUTION: Never loosen the four allen set screws in the knurled knob, the knob’s detent pins are indexed for proper jet alignment to the outlet port of the JSV body. COCKPIT INSTALLATION Drill one 1 5/8” hole and three 3/16” holes using the drilling template enclosed with the valve. Install the valve so that the outlet is to the right (3 o’clock). Insert knob through hole and attach trim plate to valve body with the three screws provided. - CONTINUED - CHANGING JET SET Set pointer in line with outlet. Remove cover (6 bolts). Remove springs (8). Remove jets (8). Before installing the new jets, place #600 grit sandpaper from the installation kit on a hard flat smooth surface and lightly lap the backside (opposite the number) of the jets to be sure they will seal properly in the valve. NOTE : excessive lapping may alter the jet flows. With the knob pointer still positioned in line with the outlet fitting, drop the richest (smallest) jet into the hole in the cylinder that is in line with the outlet (the position that is over the hole in the body). The num ber on the jet should be visible. Drop the remaining jets into the cylinder, in order from the smallest to largest, going counterclockwise from the first jet. Replace the springs. Replace the cover; be careful that the o-ring is in it’s groove. Replace the eight socket head cap screws. 1 2 3 4 5 6 7 8 9 10 Note : Numbers of steps relate to schematic on right.
