carb rebuild question, throttle bearings Options

[tat2dphreak]

ok, my set of weber 40s... they are old(built in the early 80s by his estimation). my mechanic cannot replace the throttle bearings and thus, they do not idle right once the engine gets warm, it's like they are always slightly "cracked" open, when warm.

is there a place that can rebuild these and make them "new" again? or is it time to start carb shopping?

fron what I understand, the new carbs have a plate on the front, and one on the back that can be removed to replace the throttle shaft bearings, but this set only has 1 plate, so the bearings are not replaced(at least by normal means)

I say: give it a try yourself!

I think you can get most of the parts here: http://www.redlineweber.com/

The hardest part is undoing the screws that hold on the butterfly disks. The are usually either loctited or physically deformed so they don't vibrate out. pushing hard with a screw driver on them can cause the shafts to bend. If they're the deformed style, you can trim off the deformed part with a dremel tool - then they're much easier to manipulate.

My bearings were pretty shot - they felt dry and a bit "gritty". Ball bearings don't perform that well in an "oscillating" environment... but we have to use what we can!
