Now that you are gaining more experiance it might be worth the effort to go back and look at some of what I said back when you had all the trouble with the first SSR that didn't work right. What I am getting at is for you to understand proper coil loading, not that your doing anything wrong and perhaps you do already understand but I had given you specific instruction on tuning for a coil with the MC. IN short I will repeat here a little.
You do not want to over saturate your coil ( or under saturate). Get yourself a neon if you don't have one so that you can tune. Set your off time for a very long period so that you can concentrate on your on time first. The coils resistance and the voltage will be your most influential factors in what is ideal timing. To tune put the neon on your charge side with no battery connected and make a sketch that only fires once every 30 seconds or 60, point being that you can see ONLY one firing. Set your on time to VERY short to start. Now did the neon light up? If not increase the on time slightly and try again. Go through these motions until you get a mild glow on the neon from one firing. You don't want a super bright one because when you add the frequency it is going to be stronger than it is with only one pulse. You just want to see an indication across the neon that your loading the coil well.
Now connect a charge battery and remove the neon. This is only for finding the ON time and will fry your circuit if you go to the next step without putting a charge battery on.
Once you discover a good on time proceed to increase the frequency by decreasing the off time. Does this method make sense to you? Find the ON time for your coil, then increase the frequency at which you fire that ideal on time. This will get you in the ball park with any coil, then you can make small adjustments.
