<div style="color:black;font:10pt Arial,Helvetica,sans-serif">Pushing the pin up to lift the piston is the start of the "test the mixture setting" exercise. You begin the push, ever so slightly, and listen to the idling engine. The idle goes up. What do you do next? You continue to raise the pin to see what happens. If the idle continues to rise you know you are in a rich condition. If the idle stops going up and starts to drop off the mixture is pretty close. If the idle does not increase from the start you usually assume you are in a lean condition. This gets the carb mixture close at idle which in theory means the carb is going to operate throughout the RPM range. </div>

<div style="color:black;font:10pt Arial,Helvetica,sans-serif">There is one other assumption here, that being that the carbs is in the same condition as new mounted on an engine operating as new. That is when allot of other stuff comes into play. The carb float bowl items, needle/seat and float level must be set correctly. Float must not be leaking thus making it sink. Carb must have the correct main needle and jet and they have to be installed and adjusted correctly. <span style="font-size:10pt;background-color:transparent">Flutter at high RPM may indicate that the piston spring in the suction chamber is weak or the incorrect spring installed.

Just finished repairing and reinstalling the carburetors on my BJ7. I thought I had everything adjusted properly. According to my Haynes Manuel the engine speed should increase slightly when you lift the piston a very small amount. Mine does that. My dwell
angle is where it needs to be and the car starts and idles nicely. Also sounds beautiful when I punch the accelerator linkages. The problem is that when I get it up to 60-70 mph I get what sounds like backfiring into my carburetors. Also sounds like it doesn’t
have a whole lot left in the tank, so to speak. Does that sound like I am running too rich or too lean? </div>
