The car was running fine. Then last week, it started to pop and backfire on the freeway at 70 in 5th. It did fine in 4th at 70. Later in the day going up a grade at 70, it started to backfire real bad and lost power. I pulled over and it wouldn't idle. It was hard to start and then died. Investigation found fuel on the air cleaner cover on the passenger side carb.
Is this an indication that this float is bad? Is there a way to test the float vs. the valve? Does this look like too much fuel in the bowl? Thanks, Roger |

Well I just had a chance to investigate this some more.
I decided that before I tore anything apart, I'd check the compression. Results: #1= 120 psi #2= 130 psi #3= 0 psi #4= 110 psi Obviously, #3 is the issue. I checked the valve adjustment on that cylinder and it is fine. What makes sense to me to do next is remove the head and see if there is a valve burnt/not seating. Am I going to have to drop the engine to do this? Or, can it be done in the car? l'll re-evaluate the carb and change the oil with filter after I figure out the compression problem. Brand new plugs installed after the carb rebuild. Coil must be good since there is spark. Rotor, cap and plug wires have only about 18,000 miles on them. Thanks for the input. -Roger |
