You missed my reply in "tech help"


603's are either 17 deg ATDC =/- 1 degree for the early ones and 14 degrees ATDC +/- .5 degrees for the late ones. Take and set the engine to 17 by hand rotating clockwise, remove the 17mm head access plug in the side of the pump and look for the bar marker on the governor body, roll the engine back and forth untill you find it. Then look where the crank is. It sounds like it'll be in the 20's. Then rotate it twice through back to the same place and look again. (this properly loads the advance wheel and tensioner)

In order to move it more than 5 degrees you must remove the pump and jump it. I take and lay the pump on its side after removing it with the crank on 15 and the cam in overlap on #1 and set it to the bar. I then mark the pump shaft and body with touchup paint and carefully reinstall it, then look for the bar prior to driving it home. (replace the big o-ring as well as the bottem plate o-ring and rear cover gasket while it's off.) You can gently use vise grips to turn the shaft, grab it past the splines or you WILL be skrewed.

Good luck, without the LED timing tool this is sorta a hit or miss deal.
