Re: Hard Starting Hot

If you’re talking heat spacer every carb is different.
Quadrajet doesn’t need one. Normally. Hot slot intake does.
Eddy carbs do. Usually made from aluminum, phenolic resin (think plastic) or wood.
Holley uses a shield that deflects heat from the bowls.
The position of the float bowl determines the device needed.
Quadrajet bowl in a low heat zone above the plenum.
Eddy has two bowls. Each out on the high heat sides.
Holley bowls out front and back.

Another consideration on your starting problem is your choke setting. Too rich can act like yours.
