Is anyone running a Racing Beat original 48DHLA Dellorto carb on a stock port motor with a RB header.

I bought this carb used and after a good inspection/cleaning everything appears to be good. The only thing I have a question about is the pump jet weight (#50) and ball bearing (#51) my carb has neither. Was this part of the RB mods or am I missing these



TIA

 

i think it should be there

 

I've been runing one for almost 15 years on a 80 SA stock port 12a with a Rotary Engineering header and exhaust setup. I purchased these all new back in the day. A good site to verify some things is http://www.gruntled.com. I beleive the pump weight was omitted by RB but the bearing should still be there I think. Do a search on Dellorto because the topic has come up before.

 

It must have a pump jet ball bearing. Purchase those.

RB removed the weights in their kit. I've tried 2 different sized weights and liked neither. Removed them.
