Thanks to both of you for your information.
I have a carb off a rebuilt Saracen coming from
wjrbanister@btconnect.com. He had rebuild kits available but hardly any carb shops do a flow test anymore. If it didn't work after rebuilding I wouldn't be sure if it was just my rebuild job or something else that went wrong.
Mr. Banister was very helpful and nice to deal with. I strongly recommend him.
Thanks, I might be back.
