Hi Mod CyberJack and Gatty7,
I would have to say that Jack is spot on there regarding the over tensioning so that the chain would still drive the cutter. It's definitely in the top 10 of flogged out parts I've seen.
I'm still awaiting a call back regarding the availability of getting a Series 1 tensioner.
As soon as I hear something back I'll let you know Gatty7.
Cheers,
BB
