i have a 750 brute force thats having no spark problem on both cylinders just to start this out i bought it torn up the side case was open and the stator and flywheel was exposed to rain and had alittle rust on it so i cleaned everything back to pretty decent, i know the idiot that had it personally and know it had spark before i got it and replaced all the timing chains i made sure that the key way on the crank was good and put the flywheel back in place its spinning like it should, i have also checked voltage to the coils they both have 7 to 8 volts its had the buss connector fix on front and back already i have tried a different cdi box still nothing im stumped i build engines for a living but not small engines and this is killing me

just a quick up date the pulsor coil is showing 0.004 is that bad or good?
I think that's too low but take the manual and look it up. Oh..you don't have one? Here. Also, 7-8 volts on the coils is too low. Under 11 they won't charge. Should be the same as the battery-12.5-13.2. Pull the fuse box and pull all the connectors underneath.

That rotor's retainer must be torqued to what the book says....like 90ftlbs. Otherwise it will shear and if it breaks the crank-side keyway..like some have..it's a new crankshaft.

Not sure haven't tried it yet, but i am getting spark when i first hit the starter button. While it is turning over I no longer have a spark, but when i let off the starter button I get a spark. It is not constant, is it supposed to be constant?
