A functional carb fan will reduce the chances of a warped or cracked intake manifold, smogged or desmogged - IMO.

also keeps the gas from boiling in the carb..."vapor lock".
 
Mine started hard when it was hot w/o the carb fan. Whatever it does, I like it.
 
I dont think it does anything except keep the carb cooled on engines that have all the smog crap on them. If it protected the manifolds you would see them on non-US engines. I think Toyota had to put them on to keep from having a hard start problem with engines that were choked with all that EPA/DOT crap on them.
 
mine is desmogged so of coure the fan has been unplugged, i ran a test wire yesterday to it, just wondered if I should run a toggle to it just in case?????seems to start fine, if anything, its starts good
 
As y'all have mentioned:
- fan is part of emissions 'stuff'
- purpose to minimize gasoline boiloff
- minimizing 'unburnt' hydrocarbon emission

As y'all have also noticed, rig runs better after 'hot engine restart' when fan does work.

I've 'desmogeed' but kept fan operable.

I'll second that from first hand experience. Pulled the manifold after not having the carb fan working from the PO's and the manifold might as well have been a pretzel.

P.S. Oh yeah, starts easier with the carb fan working too.
 
PO - previos owner

There's a relay, a thermal sensor, a 20 minute timer, and a schematic somewhere that I have never been able to find.

If you find the schematic please post it up.

Cheers,
Cahil
