glowing exhaust pipe,FSE 450

[houndog]

Well, She's been fine as far as I know since the plug died. It's been very cold and I'd not started her for a week at least. So I go out there and it is a no go.

Spits, sluggish.....battery goes limp. So I let her sit a little while and jump her off with the Jeep. She fires right up. I let her idle a few minutes and notice the exhaust pipe is cherry red!!!!!! I shut her right off. Wait a few minutes and start her up and ride down the road....it's like 36 degrees. Within a 1/2 mile it's starting to glow. I head back in the drive and shut her off.

She seemed to be running fine.

Any suggestions would be very nice!
