I need to setup the timing chain on my LT230S. Where are the marks for the crank and camshaft so that I set the timing. Thanks for you help.

 

Find top dead center. If you have the stator cover off there is a mark on the crankshaft that should line up with the block. If you dont have the cover off make sure the piston is at the very top of its travel.
After you have found TDC then install the cam gear onto the camshaft(w/chain on it) so that the 2 marks on the cam gear are parrallel with the cylinder head.
The best way to see this is go to the LT230S Vault on the web. The Vault has some excellent pictures and tips.
Good Luck
