So today I decided to play with my mixture screw on my 47mm oer carb to see if I can get maximum psi using a guage. guage was bouncy from 16.5 psi down to 14 so i kept playing with it. Aslo adjusted my fpr to 4psi, Played with it for atleast an hour, all a sudden car dies and when I start it car sputters then dies. Checked spark plugs and they are black, could it be a possibility I burned out the plugs. Is there a possibility I hurt my engine playing with the mixture screws????

 

if the plugs were black they arent burnt, burnt color is white

 

its weird how its sputtering then it dies, I was going to head out to kragen and get new plugs to see if it fixes the problem.

 

just tried to start her up again, idles then dies... also noticed a very bad gasoline smell... almost like un burnt gas... going to see if I have any spark on my plugs...

 

new plugs and new fuel filter.... checked spark with a spark tester, I have spark at both leading... did a compression test and got 110 from front rotors and 120 at the rear... fuel pump works... could I have done something bad to the carburetor when I was playing with the mixture screws??? any have any suggestions?
