my car is all stock except for my fan switch and thermostat . whenever i go WOT or under heavy acceleration my car gets this raw fuel smell .
BTW im running a 180* thermostat and the fan switch is on @ 200* and off at 185* and this is my average temp . unless i drive her hard she will slowly climb up to 220 *

 

Need more info. Tbi, tpi?
To me, anything less then 190 is to cool.

 

I really easy way to find out is to unhook your fan, let the engine get up to 200*F and see if the fuel smell goes away.
I'm going to bet that it doesn't, but you have to try it and see.

 

I have the same problem, my car just doesnt really want to heat up all the way. Im running a carb'd 350 and I can't get it any higher then where your needle was at in the pick, same fuel smell to.

 

Non-computer carburetors meter fuel by air volume demand, not temperature, so whatever fuel smell you have has no relation to the original post.

If you want it to run warmer you can put in a hotter thermostat, and/or block off part of your radiator.
