Hope that helps.
hi my rear arms are fine, the front lower arms are my problem. i think it is because with a 0.6mm play for new arms, it should even loosen more after i run it.

i have 2mm shims in each side, il sand an extra 1mm agree?or sand the arm?

I was refering to the front lower arms. I shave them in the rear part to make the car shorter.

I believe the lengh of the arms are 63.4, and they should be 63.0 in order to use 2 of the 1mm clips.

.6mm is a little much. I would double check your front and rear brackets and see if you can decrease the slop there first. If you can not; Kysho makes a assortment of metal round shims that will fit over the pins KY- 96641

Also Serpent makes the flywheel shims Serp-6599 these shims go behind the cone which will move the clutch assemble out to better match the placement of the spur gears.

What a relief! I never thought of metal shims.i believe that's better than sanding the shim.i also ordered the 6599part thanks I really needed that solution.

As always,u guys are truly great thanks.

Yes that is correct. The shoes should be leading the pins.

Running the weights the other way "trailing" makes the clutch less aggressive. I normally start with a clutch gap of .6mm. If traction is good I've went up to .7. .5 is a little too small for the tracks I run on. If traction is low I would believe .5 would work fine.


Pass you soon...

The long springs I believe were actually used on the 966. But some of the team drivers posted that the use of long springs on the rear of the 733 gave better performance. So i guess this carried over from the 733 to the 747. If you do a search in the 733 thread the spring rates are listed; if not, I will have to dig them up. The 747 kit came with the same length absorbers front and rear


Pass you soon...

I thought the bevel on the shoes would face the flywheel for a bigger contact patch..

They are filters, the one going to the engine in to get more mileage from one gas tank. The one going from the pipe to the gas tank is to get constant pressure.

They will be needed if there is a bad designed gas tank, the 747 gas tank has no problems with size or pressure, so you will not need them.

I use Keep-on engines with no filters at all. And have good run time (over 5 minutes) and the presure is stable (engine doesn't get lean or rich at all).
