I rebuilt my Carter Carb on Saturday, went pretty well.
Anyways, i got a little aggressive with the throttle plates and broke 3 of the 4 screws trying to take them out so i could clean them. Anyways, i'm going to drill them out and just remount them, decided they didn't really need to be cleaned. Anyone have any idea on the screw size, and advice on drilling out the brass screws? Also, as i looked closer it looks like they were melted down or hammered down so they wouldn't call out or move, i assume because this wouldn't be too good for the engine. So i assume long story short i shouldn't have ever tried to remove them, but *************** happens. Should i repeat this practice? |

Drilling brass is very easy, just use a drill bit that is smaller than the screw shaft, so you don't drill out the threads... on second thought, it might be wise at this point to have someone help you that knows the carb? everyone screws stuff up once in a while, the hope though is that you know when to pay to learn. Good luck! I guess worst case is that you break it, You might determine how available spares are, That might make a difference on how much drilling and tweaking you do before you pay someone for a teaching/learning experience.

Hate to be the bearer of bad news, but the consequences of those screws coming loose (damaged engine, throttle jamming) are just to great to mess with this. Time for a new or used carb.
BTW, I did the same thing on my 1st car 40 years ago, so don't feel alone . . . |

THx guys, i have an edelbrock 1409 coming in the mail, but it sounds like i might have some issue with mounting it. Hopefully this is not the case.
I'll get matching screws at least and see what i can do to fix them. It was primarily meant to be my backup, i had no issue with getting the car back together and everything in place. |

If you install your own screws, squeeze them or stake them somehow so that you can prevent them from turning. that's why the old ones were hard to get out...
