Kubota surging

[teachingscience]

HI all, you gave me some great advice while I was trouble shooting my Kubota L185 the last few weeks. I got it starting and running and thought all was good till this afternoon. I was letting it set and idle but after about 5 minutes it surged like someone stepped on the foot throttle. It settled back down quickly and surged one more time before I shut it down. Any ideas of why it would do that??

My b1550 was doing a bit of that until I changed the fuel filter. Had a lot of junk in it including a bit of water. Have you changed it lately?

You need to check for good fuel flow from tank to inj pump. Be sure tank vents are not clogged.

Classic starving for fuel!

I put in new filter a little over a year ago when I first got it but didn't get it to run till last week. I haven't checked fuel lines or anything yet so that'll be my next step. I was afraid of a mechanical problem in the pump or governor assembly.

Thank you all for your comments and advice.

Unless the tank was full of fuel the filter could be plugged.
