Which way do you turn a mixture screw?
On most carburetors, turning the mixture screw in (clockwise) leans the mixture, while counterclockwise (out) enriches the mixture. Initially, if the engine stumbles or the vacuum drops when turning the mixture screw in, turn both screws out about a -turn and evaluate the results.
How do you test air/fuel mixture?
How is it measured? The air/fuel mixture can be analyzed by looking at O2 Sensor data from your ECU. Another way to monitor your air/fuel mixture is with an Air/Fuel Ratio Gauge. Many AFR gauges also display lambda value.
How do I know if my pilot jet is too lean?
If the bike surges or hunts, the pilot jet is probably too small (lean). Other indications that the pilot circuit is lean are popping or spitting through the carburetor when the throttle is opened and popping or backfiring through the exhaust when the throttle is shut.
Is a carburetor better than fuel injection?
While the carburetor may have been around for over a century, fuel injection is a clearly superior alternative, delivering better power, fuel economy and lower emissions.
What RPM should a Chevy 350 idle at?
Premium Member. That cam should idle good at less the 1000-1100 RPM.
