hello, today i bought a 83 blazer the smaller size blazer 4x4 with v6. i took it out in this creek and went through it a few times kinda fast. and it killed it and i put gas in the carb and made it run. but now it will blog down and willnt go over 15 -25 on roads. what should i do to this motor to make it run ok. the area with all the air filter and top part of the carb is all dry.
