    CB200 Problem starting....

    I have a 74 CB200 that I found in a barn. Got it torn down snared down and refinished the frame then put everything back together. Wiring is back together in the right order and checked. The electric start is working correctly, fuel is feeding to the new carbs, and we have spark. Everything is working and sounding right but it won't turn over. Any help is appreciated. I'll add video when I'm able.

    Are you wearing the correct footwear?

    Seriously - did you clean the carbs or just put fresh fuel in them?

    If the thing's been sitting in a barn the carbs need to be pulled apart and cleaned. You tore the thing to bits so why you didn't do this first is quite baffling.

    OK - brand new stock carbs or brand new Dime City "one-size-fits-all-not-pre-jetted-right" things??

    Let's run through the checklist:

    Fuel? Check but is it filling the float bowl? Is it getting into the cylinder? are the spark plugs wet?
    Spark? Check, but is it occurring at the right time? is the timing correct?
    Air? you didn't say anything about this, is the air cleaner functioning? did you put a pair of shitty pods on it that are now blocking the vacuum ports in your CV carbs?

    What do you mean by "it won't turn over?". This is usually a phrase you use when the electronic starter won't engage and the engine physically won't spin. is that what is happening? if so then you have a starter and relay problem. Did you mean it won't fire?

    Also, why did you tear it apart? seems dumb.

    you might want to add compression to that checklist.

    I should clarify this a little bit. I assume you tore it down before you got it running which means whatever reason the bike was put into storage in the first place might still exist. I am pretty sure you would notice a connecting rod hanging out the block, but a broken piston ring or something similar where it's internal and keeping compression from building is not going to be notice and could still be there. In fact, often taking the bike apart can hide what the initial problem is because you get rid of tell tale marks like oil leaks and pushed out gaskets. but hey you live and learn.

    If you have a workshop manual here is what I would do if I were you:
    1) check valve adjustment
    2) check compression
    3) check fuel again
    4) check spark again and this time check timing (including that your advance mechanisim is working and not stock advanced).
    5) check that the points are not arcing to the cover (see this more on 350s and 360s but still...)

    hopefully this will uncover some issue you can then correct and get it to fire. Also, I hope you are not expecting the thing to fire on the first or second kick, often it takes a long time to coax a sleeping bike to life. my cb750K is a solid 1 kick bike when being used over the summer, but if it sits longer than a month it takes a good hour to coax it out of hibernation.
