Re: holley carb

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!

Re: holley carb

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

Re: holley carb

the carb is completely dismantle
i powdercoat only the casing of the float bowl and the corps

Re: holley carb

i did the job
came out ok after degassing at 450 for 1 hour
the only thing bugging me and it s happened for the second time
seem i got trouble to make the powder stick in the deep place of the part
the part have been sandblasted, clean whit brake cleaner , the ground look ok but the powder don t go on the deepest part
i m working whit a hobby gun from youre competitor ( i know i know)
any trick ,

Re: holley carb

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

Re: holley carb

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

Re: holley carb

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.

Re: holley carb

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.

Re: holley carb

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.

The $100.00 gun did this hulk SWEET

Re: holley carb

Re: holley carb

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.

Re: holley carb

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.

Re: holley carb

Thanks Hulk. I'm sure the carb came out great. Hey how do you but them little faces and sh@t 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 sh@t 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.

Re: holley carb

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.
