I never did get this thing straightened out.  I gave up on it temporarily over the holiday season.  All of the direction arrows appear to be right.  All of the connections are good.  Any more suggestions?  I've been watching Ebay for a replacement, but I'm not sure how to tell which ones will be interchangeable.

fzrr750 (Ed).... Please accept my MOST humble apologies for correcting you (incorrectly).  It seems that the 1976 RM370 is different from all of the rest of the RM family, in that it DOESN'T have primary kick. The 400's in that vintage, share the quirk.  According to the parts breakdown, the 370's and 400's lack a "kickstart idler gear" that the other engines have. The 370 and 400, connect the kickstart to the crank, via  the clutch.  So...  If the clutch is disengaged... so is the kickstart.  Sorry, Ed.

Thanx guys, for the tips.  I had to laugh at the advice about the primary kick, though.  I have a '76 RM 370. It does NOT have primary kick. Now I'm kind of curious because fxrr750 (Ed??) has a '76 RM250 listed.  In my book, it is listed as NOT having primary kick either. (No offence, Ed)  As for the diode....  It appears that all of my components are of the newer generation.  That is to say...  I have the coil with the red sparkplug lead and my stator is one without the diode.  My understanding is that the diode is inside the red-wire coil now??  Anyway...  maybe the upper coil is at fault.  I don't have a lot of resources around here to compare parts with.  I can't help but think that my stator and flywheel must have some life in them if they can produce a consistant spark in reverse (I used a drill with a rubber wheel chucked in and turned it against the flywheel, with a generous amount of oil in the cylinder for lube.  The spark was excellent and very consistant)

3putt...  thanks for the reply.  I've always known that many designs of 2-stroke would run in reverse with timing close to TDC, but that doesn't (unfortunatly) explain why my machine refuses to spark when rotated inthe correct direction.  On some ignition systems, the relative positions of the charge and trigger coils, can be quite relevant.  On Motoplat, however, it is not possible to move one without the other.  Regardless of timing, the CDI box should produce a spark.

I have an '84 Husky.  The original ignition went bad and a motoplat system was purchased.  The bike never ran again. It was given to me several years ago and I just got around to checking it out. There is no spark.  Once when I was trying to troubleshoot it, I had the sparkplug in the cap on the cylinder head. I was rolling the bike, in gear to try to see if there was ANY spark. When I rolled it backwards to turn around, I got a beautiful, continuous spark.  The arrow on my stator, indicates that it is turning the right direction.  DOes the top coil have to be matched with the bottom, for direction?  Any advice would be greatly appreciated.
