I have a 742 with the Ford 1.6L 4 cyl gas engine. I have been battling an issue where sometimes I start it up and it runs great, while other times, I start it up, and I have to keep the choke on, or it will start to sputter and die. Sometimes after playing with the choke, you will hear the engine suddenly clear up, and then run great with no choke. If you are running it while it is in the "I need choke" phase, as soon as you put any strain on the hydraulics, like begin to take a scoop of dirt with the bucket, the engine will start to sputter until you stop and stay still, and then it will pick back up. Any ideas what this could be? I have the electronic fuel pump, and it seems to push fuel sufficiently, but I think that could still be the issue. I do have an in-line fuel filter between the tank and the fuel pump that I try and change fairly often, but i've never been convinced thats helped one way or the other. I feel like its probably something fairly simple, since it will sometimes "heal itself" and fun fine, but whether it then runs good for 2 weeks or 20 minutes is anybody's guess. Also, I did pull the fuel intake and look at/clean the metal screen, which looked fine to me, but I have not done anything with the gas tank itself. I have also replaced the fuel line from the tank all the way to the electronic fuel pump, but I couldnt get my hands on the portion from the fuel pump up to the carb (I didnt feel comfortable pulling it off the carb, because I wasnt sure I could get it back on, due to how tight the space was back there). I can do some simple things on the engine, but certainly no mechanic, so any feedback, thoughts, etc. would be appreciated. Many thanks.
