#1 Exhaust leak, not firing. Pic.

[Billyboy]

Have a look please. #1 is not firing I believe due to fuel fouling. There is apparently an exhaust leak. I've just ordered new gaskets.

Is the exhaust leak causing the fouling problem? What the heck is this?

[chef1366]

Is that fuel dripping down the header?

[Billyboy]

Yes.

Float sticking on #1?

Float sticking on #1?

Good idea! I'll check that.

[Billyboy]

Wait a tick. If the float was sticking, wouldn't it be raining out of the overflow?

[Dave8338]

Not if it was just sticky and fouled a plug...causing the unburned fuel to find the exhaust leak.

[Billyboy]

The #1 pipe is warm, but not hot. I tried the old "lick your finger and flick the pipe" trick. It dries immediately, but not the pst! like the others. Is that a partial ignition or just warm from the other cylinders?

[Dave8338]

Looking at the fuel on the header, if it were firing on the cylinder, the fuel would have evaporated. My bet is on conductive heating of the #1 pipe along with some convection from the piston pushing out hot air.

Sounds like a conversation in the appliance section at Sears. :-D

[Billyboy]

Well, I don't know what the heck starting it, but a new plug fixed it.

Now just the exhaust leak.

Plugs can do weird things for sure.They can go bad overnight for some reason.Usually when you ride the $$$$% out of it and put it up hot.Sorta like rode hard and put away wet.I would keep an eye on it !
