For a rookie you picked one of the tricker motors to be mass produced and sold in large quantity to Joe public I must say...Mitsu makes some trick motors <img src="/forums/images/graemlins/evil.gif" alt="" />...

Cam lobes on cyl #1 should be facing "out" away from each other .. Cam lobes on cyl #2 should be facing "in" to each other ..

Think about it .. Cyl #1 is timed on the compression/firing stroke and you cant have a valve open it will just dump the compression out the open valve ..Right...

Alway check where your cams are once the belts on .. Like I said dont care about timing marks its where the cams are once I'm done that matters... One of my tricks is as soon as the motors at the point I can turn it over with the starter and the plugs in it I do ...As someone who builds motor as my day job ..I've seen a mess of motors with hyd belt tensioners jump time on the first crank over ...Mitsu's are real bad for it ...Cranking a motor over with no spark or fuel really puts a load on it .. With spark and fuel the cylinders are firing and helping to turn the motor..

And you can hear the rhythm of the motor as it turns over too..If you have a low hole ( low cyl compression) you will hear it and feel it..

Like Eddy said ... I hope you did not hurt any thing...
