Yes be sure the number one piston is at TDC firing stroke or compresson stroke and line up the timing mark pointer is pointed at exactly zero. One more thing when aligning the camshaft sprocket or sprockets be sure that when you are rotating the sprocket for the cam it is rotating in the correct direction and also be sure you observe the intake valve for number one shutting as you bring the marks up to alignment points, the intake valve and the exhaust valve should be shut when the marks line up if not you could have the cam sprocket off 180 degrees, get it right the first time or you may damage a valve trying to start.

Actually, honeymonkey, the camshaft pulley turns exactly once for every two revolutions of the crankshaft. (pretty sure that was just a mental juxtaposition on your part) That is how you get a 4 stroke engine: the piston has to go up and down twice to complete one power cycle.
Now, as for aligning the engine: This is fairly straightforward. All you need to do is to set the cam marks and crank marks to #1 top dead center. The crankshaft position can be verified with a straw or something inserted into the #1 spark plug hole and turning the engine slowly with a wrench. The camshaft position can be verified by removing the distributor cap and making sure the rotor is pointed to the #1 spark plug position AND the marks are lined up at 0 degrees TDC. If the chain or belt is off by 1 tooth the motor will not likely start, so don't spend a bunch of time getting it exactly on the line. If the marks are close enough to get the chain or belt on, it is probably right. You may need to loosen the distributor and turn it forward or back A LITTLE to get 'er started, but DO NOT do this until you are satisfied the cam and crank are timed OK. It is your only reference mark for static cam position. The motor will sound funny when cranking if the cam timing is off. Good Luck!

When setting the timing gears, where do you set the distributor?


from memory no4 on dissy when timing marks on cam timing in correct position, no 1 cam lobes should be "rocking" and no4 cylinder should be at top dead firing stroke(ignition)should be notch in dissy when cap is off or set so rotor button is lined up with cyl no 4 ht lead position
