this is a bit of a wierd problem... the car runs fine when its started (by pushing it), however it wont start using the starter motor. it turns then stops, as though the battery is flat. checked it with a multimeter, it says 12.73volts. tried starting it again while watching the engine. same problem, this time i saw smoke wafting up, which to me says its shorting out somewhere. this is where it gets wierd... the smoke was coming from where the throttle cable joins the carburetor... any ideas as to whats going on?
