GM carb'd 2.8 tuning??
I have a 84 Chevy S10 with a carbuerated 2.8. I have been having issues with getting it to run well.
When I get into the secondary it will stumble and seems to backfire and run poorly before it starts to move faster.
I was hoping it was just due to a air fuel ratio problem but it looks like when I get into the secondary it runs between 12 and 13:1 and from what I understand that is good?
Im assuming I may be having vacuum problems. When I get into the secondary the vacumm drops down low. Im not sure what the measurements are on the guage but one side sais between 5 and 10 and the other is around 100 and 200.
Can anyone please help me
