Hello All
Sorry for the delay in getting back to you. I'm out of town and haven't had a chance to check anything further since my last message. The plugs looked OK. A little dark brown to black but not too bad. Replaced them in April and only drove about 150 miles since. When I'm cruising at 50-60 MPH, it feels like there is some slight surging going on. Wasn't sure what was causing this or if it was a miss? When I put the car in gear, it doesn't jerk unless I'm feathering the pedal to keep the engine running. At idle, it doesn't jerk at all going in to gear. When cold, it goes into gear like normal. It only stalls when it's hot. I'm going to take it to a local guy that's supposed to be good on setting up carbs for altitude. Have to make sure I have the correct jets in for Colorado then set the rest up. I'm sure he can check everything out and find what's going on. This one is kicking my butt and I'm tired of chasing it. Thanks to all for your assistance. I'll keep you posted what they find.
