K & B 3.5 flex shafts slipping?

[riggerman]

Hi all I purchased several spare flex shafts for my K& B 3.5 2 summers ago noticed they where slipping on both of my 3.5 on close examination and digital calipers on the stock K&B shafts they measure 3mm on the square end on the replacements they measure 2.8 mm. Has anyone had this problem ? thats the good news i also bought 6 spares for my O.S .21 looking at them from the side the
square end is about 3/16'' shorter than the stock o.s units i will have to try to find where i bought them im thinking NY state. Regards Andris Golts

There were some that came from KB that were a little on the short side. I was able to put a ball bearing in the prop shaft to space it out. This fixed the spinning problem.

Hi Andris,

While that is positive news for me...not a help for you. As Mike said, I had heard of people using spacers but not for many years. Hyperformance, lawless and my shafts should be no worries, unless someone had a big malfunction.

LMK if I can help in any way...not sure how, but we shall see
