idles fine, but bogs out as soon as you give any throttle...if you "feather" it to get it past bog point, it seems to run ok once you get it into a higher rpm's...I have cleaned carb, disassembled and put back together...air filter is clean, it ran just fine last fall, so jetting shouldn't be a problem...please help, I am about to go nuts with this thing...

 

Do a compression check, and check the specs of the primary coil with an ohm meter, it might be one of the 2.
