2 months ago I bought a 1997 Indy 500 carb from a friend who had it since new. Last year it started to have antifreeze problems. The sled just sat with a puddle under it. He bought a new water pump and thew it in. That fixed the leaking while sitting problem. He then bought a new antifreeze cab and said it was fixed. Well its not. When it ideals there is no leak. But when I take it out for a spin and open it up it will loose fluids. It leave a mist of antifreeze under and around the motor. I'm pulling it in the heated garage now. Any ideas whats wrong or where I should start looking? Thanks.
