1984 MERC 50HP 4CYL (TIMING?)

[gasguzzler]

THE BOOK IS A PEICE OF ****. I HAVE #1 AT TOP DEAD CENTER. THE KEY ON THE SHAFT IS STREIGHT UP,IN LINE WITH #1 CYL. THE TIMING POINTER HAS NOT BEEN MOVED. WHEN I INSTALL THE FLYWHEEL,WHAT SHOULD THE POINTER BE POINTING AT. "0" OR "30".THE INFO I HAVE IS VERY UNCLEAR AND IM GETTING CONFUSED. IF ANYONE CAN HELP ,,,THANK YOU VERY MUCH MIKE

Mike,<br /><br />The flywheel is keyed and can only go on in one position. <br /><br />The book should have a pointer setup procedure. Do that once the flywheel is on. I think the setup is something like, when the piston is 0.464 inches from TDC the pointer should be pointing at a mark on the flywheel that says "0.464".<br /><br />Chris..............<br /><br />P.S. No need to shout. We can all hear you.

THE FLYHHEEL HUB IS KEYED.THEN A PLATE BOLTS TO THE HUB.ON THE OUTER DIAMETER OF THE PLATE IS WHERE THE FLYWHEEL BOLTS ON TO. SO YOUR RIGHT ABOUT THE KEY,BUT THEN THERE ARE 8 POSISTIONS TO WHICH THE FLYWHEEL CAN BE INSTALLED.THE KEYED HUB IS POINTING STREIGHT INLINE WITH CYLINDER #1 WITH THE PISTON AT TDC.DO I INSTALL (POSISTION) THE FLYWHEEL SO THAT THE POINTER IS POINTING A "0"? THERE IS NO TYPE OF MARKING THAT READS "0.464" MIKE.........THANK YOU
