Ah...that lovely ethanol garbage. The CJ started hesitating at "tip in" and then started a good ole backfire if you really stepped in to it. So it was time for a carb rebuild. This is NOT a daily driver, so feast your eyes on what happens when they sit-in particular the accelerator pump area (which is not news to those of you who have had to rebuild every last one of your mower/trimmer/chainsaw carbs and fuel lines).
Yep. I put ethanol free in all power equipment and my boat. This one is next (although we drive it a good bit this time of year). Too much sitting in the garage over winter. I'd like to tar and feather the "Big Ethanol" lobby.
