So you mean the spring tension nut set at 2mm?

I guess so... The 705 Centax spring coils are 1.8 mm thick versus 1.7 mm for the stock 710. So it's a little bit harder.

Interesting - you tried this out yet?
Is this just due to this engine or does this hold for all engines?

For me, I've got the thingies mounted between the flywheel pins, but without any grub screws.

I've always used the 705 Centax spring. Well, it depends on engine to engine but if you modify the flyweights, chances are that you need a stronger Centax spring.

I tried between the flywheel pins and grub screws and it was engaging too hard. I'm using grub screw in stock fly weights, 1.8 springs and yellow shoes.

When my JP met its maker, it deposited some of the bits of the engine as a rough surface on the combustion chamber. So now instead of the nice shiney surface there, it has a rough texture. Is this still ok to use or do I need a new one?

Would some kind soul give me the diameter of the first gear spur, and the diameter of the flywheel on the 710, please.

Thanks.

No idea on the diameter of the first gear spur but the flywheel diameter on the Centax 3 is 33 mm.

Even if I don't add a grub screw to the modified flyweights? Mine are cut so they lie between the pins.

Cheers, Mark.

I first had my clutch cut and mounted in between the pins without using the grub screws. I still found the harder Centax II spring better.
