I worked on a '74 dozer. with a 201 gas. With a Zenith 267 carburetor.
It ran perfect, but now it will start right up, and idle. after a couple of minutes it will die. most the time I need to pull the choke, and it'll start right up again, but will kill right away. With the choke in or out. Some times it will idle after restarting it, as long as I don't touch the gas.
I looked at the fuel filter, and it looked like it had crap in it, and little water. We had cleaned the inside of the fuel tank, last fall. It has not run since spring, when I had to rebuild the engine for him. So the water has to from condensation. It also had a fine rust in it. You can't fell it is so fine.
I then removed the filter and drained the tank, I had only put 5 gallons of gas into it. I had drained it when I was putting the engine back in. It looked clean then.
I put a new filter on it, took the carb off opened it up. It looked clean inside, but I went through it again cleaning all the ports inside, then closed it up. checked the flow, which is good, then I put another 5 gallons of new gas into it.
Does the same thing. If I remember right, I have the jet adjustments around 1 1/2 turns out each. It does get the intake cold when running. Before, and now.
any idea's.
Thanks, Pat
