Just want to send a thank you out to the mud community, I fixed my carb fan from the info I foung on the site. My ground was fried.

x2 to that!

My carb fan recently stopped turning on when I shut off the engine, and I noticed it was harder to start when hot (especially when parked for 5 mins to an hour).

I looked at the fan, and noticed one wire that was dangling my itself, but didn't seem to have another end that it had been frayed from. I took a lucky guess, and assumed it was a ground wire.

I stripped off a half inch of its insulation, loosened one of the bolts on the driver's side wheel well inside the engine compartment, and stuck it underneath that to ground it, and retighted.

Whattya know...carb fan clicks on now!!

It is actually not a ground wire. That being said, if the wire is grounded the fan will activate when the car is shut off. That wire should be connected to a temperature sensor that is attached to the intake/exhaust manifold.

You my find it beneficial to remove the fan assembly from the fender, remove the squirrel cage turbine from the motor, remove the motor and clean out the fine dust it seems to collect over the years. Use care with the brushes and lubricate the bronze bearings with a light weight turbine motor oil or "Break-Free" gun oil available a gun stores nationally. When cleaned and lubricated, the turbine should revolve very smoothly.

Don't mean to hijack, but my carb fan had begun to make squeeling noise, so I ordered used replacement from cruiserparts. Bitch to install (have to remove hood hinge bolts) but replacement works fine. Wild thing is, I'm not sure original was really failing. There was this large orange blob (raquetball sized) on the squirrel cage fan blades, which turned out to be a mud dauber nest! It would definitely affect the balance of the fan, but now that is' out I don't know whether the bearings were really failing or not!
