cb200 not running -cam 180 out?

Sorry for posting so much. It's not that i'm a postwhore, but everytime i walk to the bike, check shit and walk back i describe my findings. I can't use the 'modify' button as that will chronologicly fuck shit up.

Is it safe to try a 550f coil? it has the same amount of wires and the same colors...
 
Just tried with a 100% working (off my own running bike) cb550f coil. Spark is exactly the same as with the 125 and 200 coil. Spark at the points also the same, still more then at plugs. Put my drill on the crankshaft and sprayed engine starter in the carbs. NOTHING. Checked timing AGAIN, dead on.

Also did a recheck on valves. Turned the rotor on 'T' and checked valves at closed side. Gave them the 0.05 and turned the crankshaft 360, on 'T' again. Then did 0.05 to the other valves. Nothing happened.

I got a little furious and adjusted the opposite valves at 0.05. Turned the crankshaft 360 and adjusted the valves i already did to 0.05.
I did this to be sure i had the right pair of valves at TDC.

This resulted in abnormally amount of play (around 8mm) between valves and rockers. This told me my first go was the right one. I then adjusted the valves properly again.

So, i have compression (191/189psi)
I have spark at the right moment (but a little weak)
I have fuel (engine starter fluid)

WHAT THE HELL AM I MISSING?
 
SHE LIVES!!

WHOOOOOOOO!! fuck yeah!! i have no idea what the problem was though...

Took the ignition plate off, set timing AGAIN and Braap! there she goes. perfect idle, fast response all good :))

THANKS A BUNCH ALL!!

edit; i found out what the problem was... i hung the condensor between the wires for benchtesting, and apparently it needs grounding as i found out in the wiring diagram.. 3 days down the drain hahaha

This makes no sense. Is it possible that the spark is too weak. Maybe it looks OK in fresh air, but has not enough power to light the fire under compression?

Try another coil to eliminate that possibility and replace the condenser.

Try to bump start it. Sometimes a rebuilt engine takes a long time before it will fire up. I have had that situation several times

Seems you were right with the spark to weak to ignite the fuel!
 
If I try enough variables I'll usually find the right one eventually..... It's hard to diagnose issues without being close to the bike and seeing it.

Glad you got it sorted.
