| 2 "Glowing Rd Hot" Exhaust Pipes ? |
| By Greg - 05/28/2003 10:47:26 AM; IP 209.217.115.86 |
Hello,
I have a 66 Mustang with a 289 and I have a weird scenerio of 2 header pipes glowing red hot (2 pipes only. The back 2 header pipes on the passenger side).
So...I took the head off and took the valves out and checked them over. None of them were bent and they are all seating nicely. I cleaned them up with steel wool and put the head back together.
I reassembled the engine and fired it up. I have to admit, it idles nicely and I cleaned the head surface and the manifold surfaces with a razorblade and it has a nice vacuum seal. As I said, it idles and drives nicely.
So I did the check at night just to make sure the 2 exhaust pipes aren't glowing red hot anymore and there they were.....glowing red hot at idle while all of the other exhaust pipes are normal.
What a dissapointment !
I know the old manifold and carb engines aren't as tunned as the new fuel injection engines and some cylinders will run leaner then others and some will be rich, but this is very weird and I am worried about it. They shouldn't be glowing that red hot.
So, what do I do next? Could it be the carb?
I guess I could run it for a while and then try to read the spark plugs in those 2 cylinders. Last time I looked they were a little rich, but I might have had the carb opened up too much. I've closed the secondaries and put the idle back to the way it was.
I also don't have $500. to just chuck a new carb on the engine.
Any ideas?
Thanks, Greg |
