Engine Sputters Hello. I just bought a 1980 FJ40 Toyota Land Cruiser. It runs fine most of the time. However, once in a while the engine will sputter and act like it is going to stall. If I turn it off and let it sit for an hour, it turns on and runs fine. On a longer trip, I have had these problems. I stopped and turned it off and removed the carburetor filter and tapped on the carburetor with a wrench and it starts and runs fine. Do you have any idea what type of problem this could be? Thanks.

Do you still have the stock straight 6 engine? Could be a stuck float in the carb. I've also seen where the fuel lines get clogged enough to cause the problems you're having. So even after rodding out the fuel tank, it ended up being the fuel lines, where the PSI going from the fuel pump to the carb wasn't up to par consistantly. If you have a V8 conversion like I personally have, could be vapor lock also. I ended up wrapping the fuel lines in some orange material that NASA uses for heat deflection, found at high performace/racing automotive stores. Do you still have the stock straight 6 engine?
