converted tbi to carb spark knock
I have a 91 rs with a 87 305 engine. I switched over to carb and know i have a spark knock problem only when in gear and at high rpms. I adjusted the timing and it got a lot better but still have problems. the engine bogs down when the secondarys on the carb open. I dont know if i have to much fuel or to little. thanks

Re: converted tbi to carb spark knock
What carb and distributor are you using? What's your base timing? What RPM does full advance kick in and how much advance is there?
