as your looking at the engine to the right of it there is a vac T-piece just under the dis pack (coil) the t-piece either splits of collapses, worth a look, or get a can of car cleaner and lightly spray around the inlet manifold area whilst the engine is running, if the engine speed picks up you more them likely have an air leak.
That's 'carb cleaner'. Turtle wax won't do it....
lol, opps well spotted, in my defence it was late ;o)
i can just imagine a can of turtle wax spray trying to be used !!!
