    ouch. It would have to be completely torn down, as there are rubber seals inside that won't hold up to the heat. All mating surfaces have to be masked, as well as threaded holes and openings. It can be done, but it's a project.
    good luck!

      when mach says torn down that includes the butterfly plates on the bottom due to holley having teflon seals for the shafts. it can be done as mach said but what a pain
      when in doubt polish it out/ why replace it when you can refinish it

            if you shoot the part warm between 120-150 degrees it will help pull the powder into the tight spots.

              i try to make touch up right after it came out of the oven
              the part was at 200 f and the powder melt in a second making difficult to coat the missing points
              is it possible the material carb are made of is a poor conductor for ground
              or the competitor gun don t worth ....... like you says in english

                If I remember correctly the problem is caused by something called the Faraday effect. This happens in smaller recesses where the electrical fields in the surfaces close to each other interfere with one another.

                  that is it for sure. hlk you might try taking the deflector off then heat the part and shoot the recess area with no deflector.

                    Hey Hulk easy on that hobby gun dude there not bad. Works for me. LOL

                    Thanks Pickleboy I've been doing the hot part thing, but I will remember the removing the deflector thing.

                    You know I just started playing with this to do my kids quad stuff. But learned a lot from all you guys on this site. My buddies ask me where I learned so much about power coating I tell them from the Caswell chat site.

                        From reading earlier posts before I got my gun, I put the deflector discs in the tool box and never have used them. May not work for you but could be worth a try.

                          without the deflector more powder will come straight out of the tube. this will cause more to go down the hole where you want it to. just dust it lightly and you should be fine.

                            Thanks Hulk. I'm sure the carb came out great. Hey how do you but them little faces and [email protected] in the post I can't find it anywhere.

                            I'm going to stick with the deflector on mostly flat pieces. And remove it for [email protected] with a lot of nooks and cranies to hold the melted butter. Wait thats for english muffins. But you know what i think that'll work, thanks SS and Pickleboy.

                              If you go to remove the disc during a shoot be sure to turn it off and discharge first or you know what'll happen.
