4.6 MGT Starting Problem

[Nicky G]

I just bought this from someone that had "trouble tuning it" so I tried starting it the first time (drill start) and it eventually started up, then ran away on me and died on its own. So I reset it to factory tune settings and I tried starting it numerous times and now it feels like it isnt catching. Please refer to the video.

There's a OWB (One Way Bearing) in there that's slipping from too much oil residue. Remove it and clean it with alcohol. Do the same for the shaft it rides on. Just make sure to put it back the same way. It only turns ONE way.

No luck with cleaning it. Should I replace it all together?

If the cleaning didn't help, it's probably either badly worn or the outer race is cracked. Time for a new one. Hopefully you don't have a bad groove worn into the crank.
