Ok, so I pulled the truck out to run this weekend and it went about half a tank of gas going easy on it to get it back and running again and make sure my carb is set good for the hotter weather since last run in cold weather... All was going well, stopped it to wait for my friend to get his going and when I started mine back up it went for a little bit then like the transmission went out the engine was going but the truck would not move... looking at it there are no obvious broken parts so we look and I think the diff is out or something... Take the back apart and Inspect it all appears fine... Rebuild it and still same problem... I can see the clutch engaging and spining the Spur gear if you lift the truck the tires go like mad but set it back down and no go... no weird sounds either like a stripped gear or something... So what did I miss? is it the Diff?
Thanks in advance,
