When I got my H and M. they both had the mixture screws way too rich and you didn"t need the choke to start them even on cold days. After I got the manuals it said pull the choke and then move it to half choke till it warmed up. Anyway I readjusted the carbs to run as lean as possible without backfiring out the carb and not sputtering when say starting to go in 5th gear. Both of them run much better since I am sure they were carboned up. As far as ignition goes I would doubt it is the problem, but you could have a weak coil but it would really carry on under full throttle loads since it is harder for the spark to jump a fully charged cylinder under compression. My 1924 Olds gave me fits with a weak coil for 8 years until I said screw it and started chaning everything to get it to run better. Did one thing at a time until it ran better and it was the coil, but it was hard to start when it got hot. Still acted up but that was spark plug related, missing out. It had short reach W18 Champions and it should have had the longer reach W20s. Man did it run sweet when I started it today while it was warm out! Speaking of that, BOY did the thermometer fall like a dizzy fat chick on a greasy floor today! went from 56 at 5 PM to 14 at 1am here in west central IN. Ground turned white from small hail and it got so cold so fast some of it didn"t have a chance to melt. Oh yeah, on my M when I run the hydraulics it doesn"t make the gov move. It has a behlen 201 pump that runs the steering and 3 point and it doesn"t ever load the engine up even if I am lifting a big log with the boom. You can load it by stepping hard on the brakes if your brakes work good, that should get the Carb to open. Do that test at several engine speeds starting from idle to mid way to high. Let me know how it goes.
