Found the gas smell
 
Was getting a faint gas smell on my 85 at first but it progressively got worse. So I started the diagnostic found no leaks while running at any of the fittings or lines . Checked the carb to see it it was dumping gas into the motor nothing at idle ,Nice mist after the accelerator pump . Was about to check the charcoal canister but the smell was stronger on the passenger side had the misses rev the motor and low and behold a vapor trail coming from the fuel pump around the pin for the actuator . Guess the diafram has a pinhole and the mist was evaporating ,so new Delphi is coming in Tuesday.

So I'll be changing the oil to .

Always nice to catch stuff like that before it strands you.
