After a week of playing around with the new (used) motor we got it to fire, but only on two cylinders. we sprayed starting fluid into the two cylinders that are not firing and we got nothing, thought we shou,d have got something, even if it was only a rev. Any ideas?

Bad coil? Did you check for spark?
