I would like to know what the timing is at this poor running idleing speed. It should be at tdc at low idle. Far as full throttle timing it depends on what pistons and head are on the tractor. Std stock M with gasoline head was 40 degree btdc. Increased bore, flat head aluminum pistons is 30 degrees btdc. If it has fire crater pistons timing is 22 degrees btdc full speed. Having had the distributor rebuilt, who knows what advance you have in there. You need to know that and what head and pistons to make it run right. The idle mixture screw on an M is bass ackwards from a lot of carburetors and the farther out you turn it the more air (leaner) the mix. That was changed on carbs used on 400 etc to be a mixture screw, out means richer on them.
