I agree with Overboost. If you look through the forums you’ll find a number of guys with that issue and it’s usually the linkage bolt has worked its way loose.

Sounds like your guys is hedging his price on worst case scenario hoping to make a few bucks off what’s likely a very simple fix.

As Andrewwynn (I think it was) found out that arm is relatively pricey so he splinted his at the break and solved his problem for just a few bucks. If yours is just the bolt, that’s even “easier” to fix [emoji106]
