Hey guys it been a while. My son is having the problem on his 88 Sami of the gas pedal is hard to push after he has been driving for about 10 minutes. The longer he drives the harder it is to push the pedal. All the components seems to work fine when disconnected from each other, even while running and hot. But when connected back together still has the problem. We installed a new cable, and even tried running the cable a different way across the engine. This has the original carb, I'm hoping it's not that because I cant afford a new one,and it runs great otherwise. Can anyone help?
