Holley 870 street advenger - junk?

These carbs do not have removable or adjustable idle jets or air bleeds. The restriction is inserted in the jet in the metering block.
Belt pumps are the best thing since sliced bread. Never had a problem with this setup so don't think that is the problem but still ready to look further at the return jet

Yeah, I know they don’t have adjustable IFR’s. You drill them out to 6-32 and make them replaceable.

I’ll look in my notes and see what the last one I had apart had for IFR’s. I can’t imagine that it came with .014’s, but I’ve seen goofier crap than that.

How many GPM does that pump produce at 1000 RPM crank speed? I mean a 3.5 gallon pump will easily do 800 HP on alcohol.
