I have 2 ports on the bottom they are only about a 1/4 inch apart
Close enough that the different gaskets expose a different hole
I used the gasket that fit better
The cab squeals (just a short high pitched burst) only if I hit the throttle quickly form idle. It is associated with a short hesitation.
The engine also stumbles slightly at max rpm

Other than that it runs great and has good power to be honest I can live with the squeal but not the stumbling

Could all this be related to the same vacuum problem

As alway thanks for your advice it is always helpful
