Setting up a newly rebuilt Stromberg 48 Carb


Recommended Posts

If you set the float level by the instructions when the carb was on your bench, then there is little to do but install it.

Make sure that if there are any vacuum ports in the base of the carb, that the base gasket doesn't cover the port.

Most idle jets will need to be gently turned in till they bottom, then back out about 1.5-2 turns. This is generic, some carbs its 3 turns.

You will find out once it's running, and when you let the engine idle warm, turn the idle jet in till the engine slows or misses, then back out til it's smooth. Too far out will be rough running too, use a spot between the two extremes.

That should get you going.
