Spark plug gap

I also said it might just need tuning!!!

Yeah I saw that. Didn't mean to be repetitive, just meant that I think any blocks can be made to work with tuning as long as their compatible and have no defects.

Thay Do work well with Quick Fuel block and there own meter blocks Fishy! But Holleys gaskits mess match as well And Thay have two types of main bodys one that sopports 4 corner idle Circuit and another that just covers a 2 circuit. I also had one Defective 1 that no matter what I did to the carb It didn't change a bit. It had A Hole that wasn't drilled to were it was suppost to!

There are a few types of Holley gaskets but from my experience as long as you use the correct ones your ok. You gotta watch close cause all it takes is one hole to be off and things don't work, I'm sure you know that. The first go around with mine I used a throttle plate to main body gasket for an 800/850 and didn't notice one of the idle passages was off just a little towards the outside and it blocked an idle passage and therefore had no idle a/f adjustment.

Yes, defective parts sure can drive you crazy.:violent1:
