I am rebuilding / restoring a Holley 780 from a DZ motor. It is pretty badly carboned up. I had a little Gumout from about 20 years ago. The stuff cleaned and worked like a charm, but I only had a small spurt and the can was empty. So, I bought a new can of Gumout the other day. It was like baby formula! I went back and bought a can of Berryman (on the advice of this forum). It was a little better but nothing like the OLD formula I remember.

So what works? Has the EPA ruined ALL of the modern day solvents? ......Jb

I use brake cleaner in the aerosol can. Works pretty good. An old toothbrush comes in handy.

I use Brakleen for all my parts cleaning, weed killing, bug killing, keeping the wife out of the shop, etc...good stuff!

I use the Super Tech aerosol brand from Wal Mart. It's cheap so you can buy several cans and despite being a discount brand it's some mean stuff. Don't be couped up with it in non ventilated area or it's lights out time.

get some BG throttle body cleaner

that stuff is amazing

bg throttle clean or castle carb cleaner works good!!

I even clean my hands with brakleen that stuff works the best. It also doesn't leave that oily film on your parts like carb cleaner.

Thanks guys! I'll give 'em a try.....Jb
