Rebuilding a Holley 600

Those 1850's are super simple carburetors. You'll be able to get that thing working perfectly with one hand behind your back and both eyes closed. Let me know if you need any hard parts or screws or anything. I've got a good amount of spare Holley parts and pieces laying around.

Oh yeah - one thing I always try to remember to do is lightly lap the accelerator pump housing on a flat surface with fine grit sandpaper. A lot of times they aren't flat and will leak from over-tightening the four screws. It's not a bad idea to check all of the flat machined surfaces really, but that accelerator pump housing is the one I've had most issues with in the past.
