    Hard to tell from the video but it sounds like injector nailing. This can be caused by the injectir popping too soon which affects the timing as well as allowing too large of fuel droplets. This may also account for what seems like excessive shaking in the video. Did you pop test the injectors after cleaning them? Does it mellow out after it's warmed up?

    Re: MasterAce 2CT Turns over but won't start

    Cheers guys, I have some CT60 so might try running that through with a new fuel filter to clean out the "cobwebs".

    I didn't get to the point of running it warm as I was unsure of the sound I didn't want to risk damaging somthing but will give it a go and see how she sounds when warm.

    Also I don't have a pop tester so havn't had a chance to test the injectors since cleaning.

    I also remember adjusting the maximum fuel screw when trying to get it running, would this have an imact in the nailing at all?

    Thanks again for your replies,
    Jon

    There was a link to it on another thread but here it is also: https://drive.google.com/drive/folde...gu?usp=sharing
    It could do with being compiled into a single PDF but still works as is.
    Hope it helps,

    Jon

    Had a chance to run her warm this eve and I also replaced the fuel filter and put some deisel additive "ct60" in the filter & tank.
    She's running much better now no smoke, a little white to start with but now nothing.

    However still a knocking of some sort, though doesn't sound as bad:



    Any thoughts would be much appreciated.
