    Kubota 400 ci backfire issue

    I readjusted the valves to .005 and it seems to be what the issue was. It might have a slight backfire once in a while, so I will bring it down a little more one day. But it is greatly improved. Thank you everyone for your advice.

    Kubota 400 ci backfire issue

    A friend was over and wanted to adjust the valves by seeing if they were open or closed. It definitely made a big difference in the amount of times it backfires and also less impactful or power loss during backfires. This weekend I am going to go strictly by the book and adjust the valves. Looks...

    Kubota 400 ci backfire issue

    I think it is .0047 - .0059 so I put it at .005 and have to order gaskets to put it back together. I will also call the Kabota dealer and check gap to make sure. It was quite a bit off comparatively speaking. I will update next weekend.

    Kubota 400 ci backfire issue

    I did that but let it soak for a week and it is still backfiring. I now need the gap for the valves. Having a heck of a time finding them. Not sure if they are .015 and .020, want to make sure before putting it back together. Anyone help with that, since dealer is not open?

    Kubota 400 ci backfire issue

    1. I will retest that as soon as possible. 2. around .6 3. yes that is what is exactly I did with t'ing it in. When it boggs down, there are actual multiple backfires each time which makes it bogg down.

    Kubota 400 ci backfire issue

    Yes, but I did notice that is kind of pulsated also after getting it to operational temp. No on taking the injector apart. My videos are on facebook so if not subscribed or opened maybe that is why. https://youtube.com/shorts/qowwLl0inoc?feature=share
