Took my '64 Comet out for the first time in a LOOOONG time today. Had to spend about 5 minutes pumping up the Carberator to get it to start...no problem there as the Car has pretty much sat since late August. This Car hasn't seen any Highway miles for quite awhile,so that's where I took it. The ride down(26 miles...)went fine: Heater on,and that's pretty much 'it.' At the end of the journey,I stopped at a Roadside pitstop/used Vechicle Lot...waited around looking at stuff for about 45 minutes or so. Then I got back in and headed for home.....I got back on the Highway,and about 15 or so miles in,I noticed some Blue Smoke comming out the back . I let off a bit,and the Smoke let up a tiny bit. I then went back up to 65 MPH & the Smoke still stayed there for about another minute or so before dissappearing. Got off the Highway,no Smoke. Stop-n-Go Traffic: No Smoke. When I got back to the Garage,I noticed the Carb's Idle was a bit "high",so I turned it down a notch,let it run,and then took it for another spin around the Block again. No sign of the Smoke . It's never done this in all the 13 years I've had the Car. Remember,this is a 23-K ORIGIONAL 200 Engine in this Car,and I've alway's maintained it. The Car has a N.O.S. Exhaust System,the Radiator is less the 3 years old(stock replacement Brass/Copper...)as is the Water Pump and all of the Fan's Belts. I'm wondering what/where & WHY that Smoke appeared. I'm guessing that the Carb's the next thing to get rebuilt/replaced(it's never been apart before,at least since I've owned it...). Discuss. ~OO6.
