Question type: Maintenance & Repair

Greetings I have an olds cutlass with the original rocket 350 2bbl. It starts fine and runs ok but if you give it gas in gear it will stall or if going up hill it will slow down no passing gear it will die but start right back up. In park you can rev it just fine. I put new plugs wires dis cap rotor points fuel filter gas tank (had leak top side seam)fuel lines, I also did a dry compression test and they all hit around 150 psi . A mechanic I know wants to drill the jets out in my carb because of poor fuel today but I cant see it
Help I want to keep her as stock as possible

Does the car set a lot un driven? If so could just be a bad gas/condensation issue. Try some sea foam in a full tank of gas. But if gas that is in it is over a couple months old then remove all the old and add some new gas.

Thanks yes we replace the gas tank because it leaked when full a seam was leaking we thought it mite be the rubber lines on top of the tank so replaced them also, we filled the new tank with premium and added a booster no change at all in performance

If you have the turbo-hydramatic 350 check the kick down cable for proper installation and adjustment. You should also be running a lead substitute in the gas as well. HTH. -Jim

You're welcome. Glad to help. As long as you're not using oil I wouldn't bother with the oil additive. HTH -Jim
