valve timing

can the cam chain sprocket be installed in more than one position, causing valve timing problems?

Yes it can. Have, you down loaded the manual from our manuals section> If, you have it it shows the timing marks. Also why do, you ask? Did, you take it apart?

Re: valve timing

I have the manual. The engine has been totaly rebuilt. Down to splitting the crankcase. Will not start and valve timing is one possibility. After further study and verifying the position of the timing mark on the camshaft when the crankshaft mark is at "T", I'm not inclined to think the problem is valve timing. I'm getting good compression and good spark on all cylinders. Carbs were rebuilt and seem to be functioning properly. In the end, I think I'll find a stupid mistake. Already found one; connected point wires to the uninsulated side of the bolt on the points.
Any thoughts would be appreciated.

Has it poped, or tried to fire? It might be the wires to the points crossed. try switching them.

Re: valve timing

The beast has roared. Fuel line clamp not tight enough. Loose fuel clamp and a grounded points wire __ not bad for a total engine rebuild. Thanks for the comments. Buster
