So you want to go fast eh?... Our 240Z carburetor kit comes with all the bits and pieces you need to get up and running. Installation is easy and takes about 2 hours with a pocket of wrenches and a couple screwdrivers.
Step 1 "demolition"
Remove your old set of Hitachis' or Webers', you wont need them ever again! You have now just made a new paper weight or door stop.
step 2 "Nuts and bolts and screws"
Before installation, be sure to turn the fuel enrichment screw all the way to the right, then 7 and a half turns to the left. This will put you in a good zone to start tuning the air/fuel mixture a little later.
Loosely install the connecting rod between the carbs. Install the spacers, carburetors and reattach the fuel lines. Tighten the connecting rod hardware and hook up your choke cables and throttle linkage.
Unscrew the top cap and fill with the included 3-in-1 oil. You may use any weight oil you choose, but we've found this works best.
Adjust your choke and throttle linkages as needed.
step 3 "It's alive!"
"Fire her up!" Adjust the throttle stop screw to your desired idle. Since the 240Z has 2 carburetors, they should be synchronized for optimum performance. Use a carb synchronizer to achieve this, simply place the tool over the bore and adjust the float to halfway in the sight glass. Measure the flow on the other carb and adjust the throttle stop screw to match your previous measurement. Go back and forth to assure the flow is even between the 2 carburetors.
