After finding it, did you get it timed correctly?

HEY TAZZ. I myself have never found a definitive answer to this yes big case drain hole to largest port. I have gotten wrong more than I have gotten it right, retime motor hell no cross hoses hell yes. I suppose the issue arises a . book does not differanate left or right motor. in my expearince. seems to me as to which motor starts. my solution. wheels off ground bungee sticks fwd. fire it up.should be right. THE problem being. is don't always work. than you have to cross hoses.A. makes it pain for next guy.B sometimes hoses don't fit.. randy m could not answer this queston.? my trick seems to work. but still no definitive answer . one would think that after rebuild at the very least thirty or so. of these. it should be self apperant. am I missing something?

I don't like timing motors either, looking at the holes is hard to know for sure what the biggest one is to line up, you just hope it's right.
