Good Metering Block vs Wrong Metering Block.
The good metering block (1st Picture) has 4 openings on the top of the block.
It uses "Cup Plugs" to seal the drilled passages in the block. Two Cup Plugs are
shallow plugs (close to the top of the block) and are for the Idle Circuit.
Two other plugs are recessed into the metering block and are for the Main Circuit.
The bad "Wrong" metering block (2nd Picture) has 4 openings on the top of the block.
It uses "Cup Plugs" and "Emulsion Tubes" to seal the drilled passages in the block.
Two Cup Plugs are shallow plugs (close to the top of the block) and are for the Idle Circuit.
Two other plugs are even with the Metering Block top surface and are for the Main Circuit.
Avoid using the "Wrong" Metering Block design blocks if possible. You CAN swap a "Good
Metering Block" on most carbs where a "Wrong" Metering Block was previously.
