I am trying to get a YM2000 running. It puffs white smoke. My local diesel shop did a compression test and reported the first piston as 200 PSI and the second as 400 PSI. I previously had them rebuild the injectors for me. The first injector showed no signs of having fired while the second clearly had carbon from firing. What should I do next? I would like to get the tractor running fairly inexpensively to see how useful it is. Eventually I would like to rebuild the engine. Does it make sense to only rebuild the first piston? If the rings are bad may I drop the oil pan, pull the rod bearing, pull the piston, clean it, check the piston and cylinder for damage, if none then put new rings on the piston, carefully replace the rod bearings the same way they came out, and have a repair that could last a few years?

Note the paragraph under "spark". Going to need new rings at the very minimum. https://www.hoyetractor.com/trouble.htm

The YM2001,2002,2010,2020 are 3 Cyl. 24Hp.

It might be cheaper to buy a different tractor than to upgrade the engine. Besides, I have heard that the 3 cylinder engines do not have as much low end torque as the 2 cylinder ones. They are supposedly quieter though.

Three cylinder is definitely way quieter than the two!!

You would spend $3000 turning your $3000 tractor into a $3000 tractor.

And some head work?
Hopefully not like the other guy on here recently that needed a new oil pan as it blew it off useing starting fluid.

Real interesting to me. Why? I have only heard of 1 other person with the 2TR20A-A. And it was in Ga. Yrs. ago. There were 2 used tractors In Spaldings shop when I bought mine from Steve. So at least now I'm pretty sure what happened to the other one. At least the Eng. anyways. And with more of the Refurbished Grn. In the can overspray. Just happened to look at the Tag. in MTF. and seen the last 2 Dig. and 80. I ran out to check if I could see mine and it's 84.

I'm good Clemsonfor. I would try to contact him. I tried but it wouldn't let me. See if you can!!
You've seen mine run and honestly it's gotten better since you've seen it. I have my 2nd. Gear PTO. working really good. So good I have Rarely even used 1st. much at all this season. And after the last oil change I'm shocked how quick the oil pressure comes up now on a cold start with the Decompression. So try and get those parts. I hate to say it but you may probably need them before I will.
