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) |

yea, that's different than mine (IMG:style_emoticons/default/smile.gif)
on this page, for example: http://www.cbperformance.com/catalog.asp?ProductID=1254 you can see that the carb has a plate on the front AND back... one with a spring, one with just the throttle "ear"... my old-ass carbs do not have the rear piece, or have the spring on the front. the back is just a plain piece, no movement or screws. I'm really thinking this is going to end with a new set of carbs, but if these can be re-freshed for less than the $500 for a new set... |
