[QUOTE="bobcatzack, post: 124467, member: 22200"] Thanks for the observation! I would have no idea how to check if the voltage is lost when the engine tries to run. Or to attempt another method of mimicking the ignition process. This morning spent another 4 hours trying various combination of distributor settings, carb settings (which no longer leaks now), plenty of starter fluid (interesting observation .. too much started fluid makes the engine not even attempt to start), also noted the throttle needs to be in full position for the engine to attempt to start otherwise it does not even try to start. I really think I got the timing pretty well set (I have spent days and days trying to figure out the timing settings before pulling the engine .. so at this point I think I have fairly good idea of getting close to setting it right). I tinkered with the idle adjuster in the rear of the carb at many positions to see if that made any difference, it did not. Here’s a bummer, I have to leave town for 1 week so it would be that I cannot get back to the bobcat to diagnose it any further : ( Your observation on a potential electronic issue is encouraging. I might not be correctly getting the power to coil (it is currently direct from the positive terminal to the positive side of the coil, with an on/off switch in the middle). Any new wiring ideas will be welcome! Will have to try when I am back in a week. Thanks everyone!! [MEDIA=youtube]sEXHBhkMMp0[/MEDIA] [/QUOTE]
