    Thanks Steve, you are right!
    My mistake, did not pay attention when drawing on the CAD.
    I will make another Timing Cover. I think shortening the fan blades will affect the air flow on the radiator jeopardizing the cooling of the engine.

    TKS,

    You could make the fan blades shorter and also change to 5 blades, that’s what I did

    Earlier picture showed sleeve being honed out of block. I would do after shrink fit. It you match sleeve and piston home lap to a couple tenths you will not need rings. Mine has been running since 2008 with out rings

    Hi!
    Bob, thanks for the tip. I will try that on the next project.

    A very nice fan on your Demon Steve. It must push a great amount of air thru the radiator.

    Michael, did you make the same mistake as did on the timing cover? Thanks for the recommendation.

    I decided to make another Timing Cover. Already prepared the material.

    No, I just made the fan to big, it was one left over from the silver bullet, but it gave me the same problem, so I made a 5 blade fan with a smaller diameter

    Hi!
    The new Timing Cover is finished.

    The one on the left is the correct one. I will sand blast to give it a cast appearance and eliminate the marks of the tool. I’m thinking to do the same on the Block and Heads.

    Clearly, you can see the difference on the position of the hub (5mm). Lack of attention when drawing on the CAD (Fusion 360

    I have sand blasted the timing cover and assembled on the block to check if it is OK now.

    Thanks John!
    I liked how the sandblast finishing come out.

    As I said before I plan to sandblast the block and the sides of the heads.

    Hi to all!
    Need help:(
    I could not find information on the plans how to time the camshaft with the crankshaft. I tried to do it on my way with my limited knowledge but it did not work.
    Could someone help giving me some hints/tips on how to time the camshaft?

    Thanks,
    Edi
