big vacuum leak, check the carb mounting nuts and the brake booster vacuum hose

think I will just replace all the vacuums lines, and the carb it looks original, any ideas on where to get a carb at a reasonable price? or a carb modification, im not a fan of the choke on there.

new carbs are available from Weber Carbs Direct, or Pierce Manifolds and most of the Fiat vendors. You can get a replacement with an electric choke. But I'd check your mounting bolts before spending the money on a new carb

Mark is absolutely correct. Grab a 13mm open end wrench and make positive those four nuts that hold the carburetor to the intake manifold are all tightly holding the carb to the engine!!

won't be the first time this month that a loose carb was the #1 culprit....Right Chris?
