So this afternoon a gentleman by the name of Eugene from sunnyvale tuned my carbs for me, I thought this would solve my issues of the car bogging and sputtering. The problem resurfaced while driving to Gilroy. We stopped three times and tried leaning and richening the mixture among other things. When we got to Henry's house we took apart the carbs and cleaned them while Grayson kept adjusting them. Once again we thought the issue was alleviated and the car was running amazing on a quick drive around the block so Henry and I decided to try taking it to Heckers. No good once again. So i bogged and sputtered it all the way to Matt's house where i am staying. What should have been a 25 minute drive took more like 45 minutes. The car feels fine if im just driving around or whatever and the RPMs keep moving. As soon as i start going up hill it will start bogging and it feels as though the car is running on three cylinders. Also getting onto the freeway is fine but as soon as it hits 3500RPM it starts bogging. It has to be an electrical issue, does anybody have any idea what it could be? I took a look at one of the spark plug but its only grey and looks like the car was running slightly rich, which it was. Also i can full throttle it all the way to redline and it will drive just fine. Only when it experiences load by driving up hill or if i try to go on the freeway will it start to die. PLEASE HELP!
