"Hi Guys,

"Hi Guys,
I have 2 new Crusader Classic repowers where the carbs are very uneven front to back. The front of the engines are very high and I suspect carburation problems could result. The boat has a planing hull. How much angle is permissible? The carbs are Holley squarebores with no external float adjusters. Thanks, Jon Allen"
 
Most straight inboards should

Most straight inboards should have a 12 degree spacer below the carb. I've got aluminum squarebore spacers on mine.

"Mine is set back about a degree or two--and that's too much where I'm concerned. Better to have it angled forward a few degrees, for the boat angles up while on plane.

"My only other point is that there are automotive wedge spacers out there at around 5 degrees, I believe. And those are usually not enough angle. My 12 degree ones, on the thick side, use a seperate set of hardware to attach the carb, different from the attach to the manifold."
 
"When we did the rebuilds this

"When we did the rebuilds this was an area of unexpected difficulties. The studs are longer than the auto versions to accomodate the spacer.

Also, the replacement studs are straight. You put them in and drop the wedge plate over the gasket. You then bend the studs until they are perpendicular to the top of the wedge plate.

During the teardown, one stud on each manifold broke...Lots of fun getting those stubs out."

My 12 Degree wedges are the same as Dave's. The mount in using those allen head cap bolts. They seem to be about 5/8 - 3/4" thick on the one side if I remember correctly.
