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 |

Generally, major damage is indicated by LOUD NOISES. If I were you I would be erasing everything I think I know from my brain, and start gathering facts.
Adjust all the valves. Even the ones you just did. Make sure you're doing it right. Check the compression on all four cylinders. Do this with all spark plugs out and with the throttle completely open. Make sure to disable your coil while doing this test. In my opinion, to worst thing you can do is guess at what the problem is. Test, test, and more testing will lead you down the right path. What carb linkage do you have? |
