JD 250 power loss

[hardatwerk]

I tried finding some info on this forum about this and many other problems this machine has. At this point this is the most serious. What happens is all of the sudden it looses power and emits blue smoke but nolt always with the smoke. I have to bring it to idle wait a few.seconds.and then crank it up again. This can happen once a minute or six tomes a minute. It tends to happen more often under load especially going uphill. Anyone else experience this on their machine or with another make pssibly. Please help as I need this machine working properly. Thanks to all.

Have you tried the simple things first?
New air filter?
Is it a turbo machine?

I have seen rocker arm studs break on those. If a turbo was out it would be doggy all the time.

Try replacing the inline fuel filter. The electric fuel pump is mounted on top of the fuel tank. You will see it nearby. I also had low voltage one time to the fuel pump caused by dirt/dust in the key switch. Took it off tapped it on something and blew out with air. Also drain the filter/water seperator if you haven't.

I had similar trouble with the new Holland. I thought it was fuel gelling but after replacing the fuel filters it's ok. The inline one had a lot of restriction.

Classic case of a partially plugged fuel filter
