I have an 88 suzuki samurai with a 3k carb installed on it that when under heavy load for a bit or an incline it starts backfiring and then stalls out or looses all its power. Not sure where to look with this thing whether its a fuel delivery issue or timing I have pretty much redone everything fuel related up in the engine bay but havent touched any of the fuel lines under the vehicle. I have noticed the filter does look empty and doesnt really fully fill up most of the time but clean gas does seem to come through and the filter isnt dirty. Just wanted to ask here thanks!
