No I dont sell bearings anymore so thats not why I am saying this LOL.
i hate to give up on the motor because when she gets on the pipe she is ballistic...bobMy findings are that the Mac O/B is a Kantankerous Kod of the highest level. You have my sympathies Bob,, Good luck!
Your absolutely correct there, they can come un-corked like no other. The problem is getting it to do that consistantly.i hate to give up on the motor because when she gets on the pipe she is ballistic...bobMy findings are that the Mac O/B is a Kantankerous Kod of the highest level.
