I have been working on my new car a lot lately and it just when I thought I had the bugs worked out of it and then I went for a ride in my TA yesterdayand after about a 40 min ride the car "jumped" a couple of times, like I was tapping the throttle, so I let off the throttle as I was rolling and it idled for about 30 seconds then shut off. Now it does not have spark. I know that these cars have had lots of opti spark problems but I do not know the symptoms of one... what can I do do check what is wrong? Currently my flywheel is bad so I have to push start my car so keep that in mind, I can't just hit the key and try something. any help will be MUCH appreciated.
