I bought an 89 js550a a while ago and have rebuilt it from scratch. New everything:

Pistons
conrods
crankshaft rebalanced
spark plugs
cylinder head
carb kit
full gasket kit
flywheel
stator plate
starter motor

Have try'd starting but it turns over but will not fire. Have checked he spark plugs and they are sparking, there is fuel getting into the cylinders but can not work out why it want start. Tryed using easy start straight down the carb but still want fire. Can anyone help have run out of ideas.

Have checked compression and both cylinders are good 120psi each. swapped the ignition leads around to make sure the timing wasn't 180 degrees out and still would not fire not even a fart. Could it be possible that the spark is not good enough under compresion if so what woul cause it to brake down.
