I'm getting ready to do my annual spring tune-up on my 70 RR 440 +6. I just had my carbs professionally rebuilt. The rebuilder set them to 69 carb specs. He said they will run a little "hotter". My question is, should i try a hotter range plug, std plug or colder range plug. I also use a mix of 110 octane & 93 crap gas to keep pinging down. Without the better octane, i always had some pinging. Any suggestions & help is appreciated.
Also a few days ago i left the key on "run" for about 3 hours without the car running. I have electronic ignition. Should i check for any damage anywhere in the system??
