So I have this 305 tbi. A few weeks ago I was helping a kid make a fun video and was revving the engine a lot in park, like A LOT. You know, the kind of stupid thing you do to make a kid's day. Well anyway, now when I "punch it" and go full throttle, I get a burning smell in the cockpit. Im afraid to ask what the possibilities are. I can tell you this, it does not smell like burning oil and it does not smell like coolant. Its allllmost a brake smell, but im not braking when it happens. I need to get under the car and have a good look around. Maybe I broke something important. Trans is full. Oil is full. Coolant level looks good. But something is definitely burning. It stops the second I back off and drive normal.

 

Slipping belt maybe?

 

Thats one I didnt think of. I will look into that! I hope its just THAT! It kind of does have a rubbery burn smell now that I think of it. Too much power in that 305 for the belt to handle haha...jk. The belt is somewhat old-ish. It can use replacement either way.
