Jinma 354 no high range power

[Bob Rooks]

At the very least I would recommend changing the oil in the injection pump. Engine oil is just fine.

I second that.

I have 354e and the tractor ran away with me thought it was going to blow up but did not find came down. I replaced all top end gaskets last winter. Now I have low range speed good power but high range will run 2nd grea but 3rd starts to bog down and dies in 4th. New filters. Have not touched the high pressure pump thought trash could be in pump but don't know how to start.

I have a similar tractor that ran away on me as well. Were you able to resolve the low power in high range issue?
