to clarify the issue further, the machine would crank but not start due to no spark. if you disconnect the 4 pin connector on the Dist, it would spark and run briefly, the controller cuts off the fuel supply if it does not get some feed back from the dist.
I replaced the ign. module, the sensing coil. and Ign coil. Ohmed out every wire. No Joy....
I sent the electronic govenor/ ECM off to have tested, initally it worked fine, but after a couple of starts it duplicated my problem on a different machine.
Soooooo. it was a computer fault, i am now waiting to see if I can get it rebuilt, a rebuild to replace it or a new one..
Thanks for your assistance.
