Unless the timing has been disturbed previously it will not need adjusting, do you hace running issues?

some noise can be coming from an exhaust shield although i cannot seem to know what type of noise.going underneath truck and kinda start tugging or pulling around engine area and exhaust also check drive shaft.

does it lock up in any gear? sounds like blocking rings trying to stick, what type oil did you put in it?
should take auto transmission fluid

The neutral safety switch is located inside the the case cover where the front sprocket is. Should be just below the sprocket.

clean the carbs...make sure you clean the jets!!!...put fresh petrol in it..& fit new plugs...also make sure the battery is charged up & in good condtion

sounds odd your motor and tranny are seperate if it goes in neutral then the transmission is disengaed sounds internal pull the spark plug and see if it turns then maybe a vlve bent timeing chain many reasons this could happen do u have any more info

It sounds as if your neutral safety start switch may be failing. This switch only allows for the safe start of an engine when the automatic transmission is in either park or neutral. It seems when you move around the gear selector you get it back to a spot where the switch allows the engine to start. Next time this happens while in park, try wiggling around the gear selector or place your foot on the brake (so you don't roll away) and place the transmission in to neutral. If it fires up you know to either adjust or replace the switch for the park position.

I hope this might have helped,
Tom

sounds like the motor or transmission is locked up
