That explains why we get it running correctly, but press the gas hard and then runs rough. Let it sit and settle down, play with accelerator a bit and runs okay again. Different pressures, sucking different amounts of air.
Bottom up.
I have a gasket between manifold and black spacer.
There is not one between phenolic spacer and bottom of adapter plate for carb. Seems like there should be. Would it hurt to put one?
Carb to adapter on our setup has a gasket.
There is a metal shroud coming out of manifold that sticks up high enough above the phenolic apscer to go into carb adapter. I guess this keeps everything aligned, but is not air tight.
