OK, putting together a cx500 that has not run in 3 years. Ran all new electrical, have spark from plugs - checked by pulling plugs and putting them on heads, gas in carbs - check bowl level with clear tube, tried spraying starting fluid in carb - removed air pods to do, carbs cleaned and new main jets put in, new battery. The battery is a small battery that is a 12v 5amp. Is the amp rating too small? What else have I missed? Thanks.
