My weber likes to eat springs! I just go to my local parts store and buy surplus springs! I've had them go south on the road before! Nothing like the pedal going to the floor and having to get your big toe under the pedal beofre you over rev the motor feeling! I'd post pics, but my weber is on a nissan!
I would asssume that your vaccum lines should run to the manifold? I had one vac line go to the base of my carb and one to the manifold! I know that Toyotas have way more vaccuum lines than a pos nissan does! Good luck! Try getting ahold of kyle22r? I believe he has a weber on his toy!
