    MowerMedic77,

    Welcome back!

    Let's back up a step here...
    The "incoming signal" to the ignition coil would begin with the flywheel... Being that the ignition coil is fixed in place, and the flywheel actually spins to trigger the ignition coil, what does cam timing have to do with it? The ignition coil has NO idea and could careless about a piston, valves ect... It only takes orders from the flywheel...

    One day I hope to maybe goto school on this stuff and learn all about it, then be a professional mechanic and who knows, maybe even own my own shop... A boy can dream...:rolleyes:

    I think what MM means, as I do. There isn't a thing wrong with it producing spark.
    The reason it won't start is a timing issue and probably has enough spark to knock
    you on you're butt. Just a misdiagnosis. It makes no sense.

    See that Ricky he's a smart one, he gets it...
    I was trying not to have a battle of wits with an unarmed person but here we go....
    Thank you shade tree Jeff for your warm albeit insincere welcome. I think further education for you is a great idea! Start with that GED and move onto some community college. Pickup a Popular Mechanics mag and find that card in the back for an online small engine class, who knows you might be able to get a job at a golf course or I know a go-kart track! I think that is just your speed tune-ups, oil changes and tire inflation. I say this because I doubt your ready for the pace and volume required to work in a real shop that would require you to diagnose and repair 10-12 pieces of equipment daily not just guess and throw parts at it praying every time you pull the rope "please start this time" I also doubt any busy dealer with well trained and highly payed techs will be happy having them stopping to hold your hand all day.
    I know I will be ready for the next faze of digital ignition electronic fuel managed[Oh yeah that's coming] emission compliant 2cycle and 4 mix equipment... will you?
    I have an idea.... maybe pop a squat under the old shade tree and wait for it to bare some knowledge fruit. Then when it ripens drops and bonks ya on the head... maybe then you will be ready.... but I doubt it....
    OP your in good hands with shade tree Jeff helping you, hopefully he can get ya back up and running before next summer or you run out of money!
    Thanks everyone this was fun but I got real life issues to take care of so until the next time I got nothing else going on.... see ya

    Ohh, I must have misunderstood the OP then... See, I thought the OP stated several times that he had NO SPARK... IF it was "producing" spark I would think the OP would have said "I have a BR600 that has spark, but won't start", no?

    OK guys here we go. Got the new flywheel today, first thing I did was hold a screwdriver upto the magnets of the old flywheel and the new one. The magnets in the new one were atleast 5 times stronger then the old one. Installed the flywheel and checked for spark, nice blue spark. Now I know that the manual says to use the ZAT 4 tester, but I dont have one. Installed spark plug and fired right up. It runs like it did when it was new, in the process of putting it all back together, I found that the throttle was only opening maybe 2/3 for god knows how long, because since I've owned it I never checked throttle opening. Thanks to all who replied.

    Well WJC, I don't think anyone will use an impact gun to remove the fanwheel.
