Rebuilt an 88 blaster. This is the second blaster motor ive rebuilt. Had bottom end all apart. Just got it all together. It seemed to shift fine on the bench before I put the cases together. I watched ken oconners videos and had a clymer manual and took my time to make sure everything was just right. Started it up and runs great. It sits in neutral and I can feel it try to go in 1st, second, possibly third, but it goes no where. Feels like its stuck in neutral or the gears don't grab. Could it be clutch adjustment? Ive never adjusted a clutch before but pretty sure it went together correctly. Not sure where to start.
