Can anyone tell me the procedure for timing a Yamaha 9.9? It is fairly old, probably a mid 1980's model. I find the numbers 1 & 2 stamped on the cam gear and a dot and a verticle mark on the flywheel. I tried lining up the numbers with the dot. The motor turns free but will not start. Lining up the numers with the verticle mark causes valve interference with the pistons. I will order a manual, but would like to get it running today if possible. Thanks. Carlwil
