Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Vacuum tube and where to put it.

I have a 1982 4/4 1600 with a cross flow Kent engine. Foam air filter in place of the massive cast unit.

I would like to know if anyone knows the correct place to plumb in the distributor vacuum. I have had a few running issues recently (revs drop when hot, unstable idle etc) and I am making sure everything is plumbed in correctly. I may have completely botched it up when taking the original air housing off. I am used to British bikes!!!

I think there are two places it could go, one is a tube coming out directly underneath the autochoke, the other is a strange coupling that comes out of the manifold, just below the flange where the carb meets it. This second outlet has a junction, one tube goes to a plastic box attached on the side of the engine and the other was hanging free!

Have I connected the correct outlet to the vacuum, or is there a better choice?
