Does anyone have a link to a site where there might be pictures or drawings of disassembling a 4150 Holley carb? I took off the float housing but could not get the metering block to come off. I tried to put a chisel between the carb and the metering block and hit it lightly with my hand - but it didnt budge. I didn't want to scar it up or break anything so I just put it back together. I need to get to the power valves.....
I'm still having issues with only having 2.5" of vacuum at idle....

Depending on how "stuck" the gaskets are, the chisel method can damage things. The best thing I found to work is a rubber mallet on the top of the float bowl to be removed. Once removed, you can get non-stick reusable gaskets from holley.

The float bowl came off fairly easily. The metering block is what I'm having trouble with.....

I agree with the rubber mallet approach. I've busted many of them loose.
