    I am trying to find the proper timing marks on the camshaft of a R30. The manual shows them in the gear but there are none. There is a circle on the outside pulley and a pointer on the bearing carrier.

    If you really get desperate the "hot rod" shops will sell you a degree wheel.

    This is put on the front crank pulley and TDC is located by pulling an injector and using a wire to observe when the piston is on top.
    A pointer is made to point to TDC 0deg on the disc.

    A dial mike is more accurate , but the angle of the injector usually makes this impossible.

    Then time the engine to the book specifications.

    I am trying to find the right spot to engage the gears on the camshaft with the crankshaft. There is supposed to be a mark on the camshaft gears according to the manual, but it is not there.

    Go to your local hot rod machine shop, and have the cam measured .

    Not very expensive .

    Tell him how the engine fires and where the crank index is in relation to #1 cylinder firing and he will be able to mark the cam for assembly.

    Hot rod machine shops are, unfortunately, a thing of the past. I can use my dial gauges, etc., but it is much simpler to know which mark is the correct one. Even if the cam is measured, I still have to use the other mark on the flywheel. The flywheel alone is about 140lbs.

    IF and that is a big IF you can find out the origional cam timing locating the cam shaft bty measuring the lift with a degree wheel is not that hard.

    What will be hard is finding the information!

    Good luck as , I have zero ideas on where to search.

    I found the camshaft timing, sort of. The manual is really horrible, with very poor information. I should be able, by trial and error, to find the right setting. This is taking way more time than what I estimated :(

    Gonzo, this is the type of mechanic work that separates the men from the boys.

    This is what separates the properly designed engines with marks on the camshaft with the rest ;)

    I had the same problem once, on a Briggs and Stratton 5hp. I tore it down about 10 times before I got it right.
