Hi Mark,

I corrected my cam timing today with the woodruf keys. It really really improved the rough idle I had before. Itīs rock steady now. I also had some driveability problem before especially after cold starts when the engine was powerless and hesitant until warm.

As far as I can tell this is also cured now.

Good Luck,
