Novarossi +4 question in an mp9 TKI2

[The Chef]

I'm about to make my first venture into nitro racing and would like some advice please.

The MP9 supplies a chonicle collet for the crank shaft but the +4 appears to be supplied with one attached already that appears to fit the kyosho clutch bell perfectly could anyone clarify this please?

And once the clutch assembly is installed the instructions state to run th 20mm O/D shimm but the crank shaft O/D is bigger than the shimm I/D.

Advice please as I don't want the maiden voyage to be fatal or wreck anything mechanically that is down to incorrect assembly.

Thank you.

I think everyone's at Neo buggy dude and I'm far from qualified to answer...

Use the tapered collet supplied with the flywheel not the engine as the taper angle varies between manufacturers. Do a test fit assembling the flywheel onto the engine as some brands of engine require 2 x flywheel spacer washers to achieve clearence of the crank case (item 121 in the manual 7x11mm washer)

Once the clutch is assembled the large 5x20mm shim goes on first and should rest against the clutch nut so doesn't need to go onto the threaded part of the crank.

Thank you I shall have a look when I get home.
