Hi, all.
I’m a relatively new member of the forum and essentially a novice 2-cylinder mechanic.
I have a 1941 Model H hand start tractor that was largely restored when I bought it. I’ve done a little work to get it running, and it runs well: it sounds and seems to act pretty good when running, as far as I can tell.
Starting the tractor, though, is a little inconsistent. A few times, it’s started very easily when I turn the flywheel. Other times, I can spin the flywheel for ages and not get anything. I’ve noticed that on the first spin after sitting for a few hours or overnight, it really sounds like it wants to run, and sometimes will. If I can’t get it started on the first spin or two, though, that’s usually a sign that I’m not going to have much luck starting by hand. I can pull start it pretty consistently.
I can imagine several possible causes: too much choke, not enough choke, too much fuel, not enough fuel… maybe a weak spark?
Rather than trial, error, and guesswork, can anyone suggest a systematic way to troubleshoot the problem? Any other thoughts or pointers?
I also have a ‘41 Model A that I can start by hand very consistently, but I may not yet know the quirks and personality of the H.
Thanks!
