    Default Kubota B8200HST Problems

    ok.... I have a 8200 HST- and was having problems with it missing on cylinder 1 (closest to the radiator) so I did a compression test and got the following results
    cyl 1 = 350 dry 365 wet
    cyl 2 = 350 dry 360 wet
    cyl 3 = 400 dry 415 wet
    after that I did a leak down test and all were good so I took the head off and had the head reworked with new springs/valves etc
    after I installed the head back on I am still getting nothing on cylinder #1
    I can take the exhaust manifold off (muffler)and it's cold as ice out of that #1 exhaust port
    now I can give it some throttle and run it up to about 2200rpm's and #1 will try to fire but will not keep firing
    I have triple checked the valve lash and all looks good there
    have also checked to make sure there was no air in the line on the injector
    Also swapped injectors to see if that was the problem...no luck on that one ???????????????

    any help or ideas would be greatly appreciated as I am scratching my head now

    When you say you can pull the exhaust manifold and #1 is cold as ice, is there an excess of raw fuel in the #1 exhaust ? If #1 is not spitting raw fuel then that says injector or injector pump, since you already did an injector swap then the pump is suspect. Of course is there is raw fuel this all goes out the window.
