Loose Dominator boosters
 

I see old style Dominator carbs that have loose boosters and wonder if this is common and if it needs to be addressed. Does it hurt anything and what is the remedy? Is there a simple fix?

I too have an older dominator with the same condition.
It has never cased me any problems though, runs like a top.

Part # 1014-798 Holley will fix the problem. Replace the transfer tubes and the venturies should tighten up. You probably have metering accuracy issues due to air leaks around the venturie to transfer tube bore.
Good Luck.
