I am reassembling my '96 250 I have followed the manual as best as I can, I lined up the "T" indicator on the flywheel I am trying to follow the directions for assembly of the cam, " align the timing marks on the cam sprocket with the top of the cylinder head and install the cam chain over the sprocket" How do I know that I will not be out 180*, and what piston fires first, left side or right side. Which is #1 and which is #2?

Further on the cam assembly, if I continue with the assembly as things are lining up, the right cylinder will be on compression, however if I turn the cam sprocket 180* then the left side will be on compression, who's up first?

Both cylinders fire at the same time. So it doesn't matter which coil goes where.
That is interesting, so as I understand this both spark plugs fire simultaneously and one fires the charge in the fueled cylinder and the other spark is wasted. I was not referring to the coils just the positioning of the cam relative to the crankshaft. That is why the directions don't differentiate the difference. I was somewhat confused because there was a post where about no spark after a rebuild and the comment was "you might be 180* out" If the foregoing is all correct you could not be out 180* because they both fire at the same time. Thank you very much for the info. I can finish this project now.
