The air filter was recently replaced (last 3 months). I used fuel-injector cleaner last night in a futile attempt to get rid of the noise. Nuttin.
It bites enough that I have a manual choke on it (which I always bring down once the car is warmed up). I'll get the exhaust system checked, hopefully before it gets worse.
Nope the engine doesn't leak, as far as I know. What would be signs? Pool of fuel on the floor?
PS Yes, I know I'm a n00b
