Hi all,
I am currently trying to fit a new engine in my f1, a zenoah G270rc and when I go to put the clutch on the engine I soon found a problem, the thread inside the taper of the crankshaft isn't deep enough to fit the grub screw on the clutch, but it is fine on my other engines, here are some pics to explain,
Zenoah taper ( red dot indicates the depth)
Cy 26 taper ( also tried a zenoah 26cc and it's the same depth)
This is how much deeper the thread is,
And this is what I need to fit
Is this a problem with the engine? What can I do?
Thanks for the help
