TSX-756 Choke Valve Position

Post by Roger440IC » Sun Jan 22, 2023 3:58 pm

I have a question about a 440ic carburetor that I hope someone can answer:

Should the pressure relief valve be positioned in the upper or lower half of the choke valve?

While rebuilding my tsx756 carburetor, I removed both the throttle and choke valve plates before reading SM-2024, where it recommends making note of the position of both before removal...

Thanks,
Roger

If the choke is on, the flap should be able to open to let a little air in, so if it makes sense, the flap is downstream relative to airflow.

Thanks Lavoy, that makes sense.

Should the flap be positioned above the choke shaft or below it?
