Default Mugen mtx3 clutch

Does anyone know where I can get a clutch kit for my mtx3??
Everyone is either on back order or discontinued? It seems to be the same number as mtx4. Also, does anyone know of any clutch I can use instead? Maybe an upgrade of sort?
Thanks

Default Clutch condition

I thought the clutch was supposed to be in 4 pieces. When I took it appart.
It was in 4 equal pieces. The ones I see online are one solid piece. They are on BACKORDER everywhere. I have no clue what I'm gonna do?

Was the MTX3 not the same as the MRX3?

What parts do you need? There are four flyweights and one shoe.

Here's a shoe at amain:

Default Mtx3 clutch

Thank you guys for all your help. I found it at AMAIN.
Can anyone explain to me the difference between a single clutch shoe that I ordered now and the 4 piece shoe that came with the kit? I know I have a clutch problem with this, the brakes are not stuck as it rolls properly, only starts to move at high revs. I am kind of new to onroad. The 4 piece that I pulled out of this does not look worn at all! Certainly not what I'm used to on my buggy. The clutch bell looks to be fine also. I ordered both of them anyway. One more thing I put it all back together double checking all of my clearances and tolerances and still have the same problem. Nothing is binding at all, I am not getting any low speed clutch engagement. I am going to try a single clutch shoe and new bell to match and hopefully it makes it right.

The mtx3 has whats called a centax clutch, vs centrifugal clutch in your buggy. Those 4 weights dont contact the clutch bell at all, they expand outward and force a pressure plate that big 1 piece sits on, into the bell. Unfortunately the gaps needed to make a centax work right are very tight (youll need calipers to measure, not something you can eyeball). The reason its not engaging until late is either; you have the clutch nut adjusted too tight (that washer that fits over that spring tunes the engagement point/rpm), OR, you have the gaps set wrong with the bell sitting too far away and its just barely touching.

The four pieces are the clutch weights, The single piece is the clutch shoe.

look here this should get you started.
