As for spark plugs, avoid Platinum like a COVID party. Platinum has some awesome characteristics; none of which make for a good spark plug. Iridium plugs are fairly decent. Both Platinum & Iridium were created to meet EPA-mandated 120k mile tune-up schedules. I have found Pulstar Plugs to be awesome. I discovered them in their 1st generation (1G) incarnation back in 2008. Since then they dabbled with Platinum & Iridium (2G). Currently, they have found a way to combine the awesome spark potential of their 1G with the durability of their 2G plugs for the 3G version. I have 3G Pulstars in my Jeep GC. Generically speaking, a good NGK standard plug with a powerful coil will get you an effective spark.

I just took out the ngk plugs, they ran like my automates and champions... I can't tell a difference between them all.

I think my carb is flooding on the start.

Not to pile on, not my intention. But whoever told you you needed more cfm and adjustability than a 650 AVS2 doesn't have a clue.

Holleys can be tough if you don't know what you are doing with them.(especially being clueless with them, like you said you are). Hopefully you get it figured out.

I chose to want to go to a Holley (brawler) and no one told me to switch to it for any purposes. Imo the brawler is more adjustable with 4 corner idle adjustment, ability to switch out metering blocks, dual feed fuel line, etc. The AVS2 is a good carb though.

Thanks for the good luck.
