First, pulling the little plug in the manifold is not a valid engine diagnosis test in any book or school of thought. Opening that up makes a good engine run bad and a bad engine run worse.
Second, you probably have the timing significantly retarded at this point. The tractor will idle VERY smoothly with the timing retarded, but it will not have any power, and won't accelerate smoothly.
For all we know you may have already fixed the issue, but with the timing being so retarded, it still lacks power.
There is one "sweet spot" where the timing is just right, and it's nearly impossible to do with a timing light. You have to keep tweaking it until the engine accelerates smoothly and develops maximum power. A keen ear can hear when you hit the sweet spot just listening to the engine run at about 1/2 throttle.
There are only two ways the tractor can jump time:
1. Someone left the distributor loose, and it rotated.
2. Something broke in the cam geartrain. However, if something is broken either the tractor won't run, or you will be chasing a moving target with the timing.
