Try to use a little less caster and or 1-2 deg rear tou before messing with the rear diff. A softer rear diff will give you a little more turn in but u will lose rear stability under braking and it will be harder to go on power hard after the turn (if the grip is hi)

that's the reason that i am worried about.
Less caster is good for entering a corner, but how about when powering out of the corner?

We only have perminent tracks here and none is anywere near that small... I would go with lesscaster and if possible a front diff so you have real braking

most of them running foams, and if i change to front diff, i have to run rubber tyre which i've never driven one before
race is this weekend so i am afraid of losing out practice time if i have to learn a new Full Diff driving style...

I've never seen PVC bent like that. I've heard of tracks using fireman hose ( if i remember right ). Maybe it's that?

The black diposites on the alumminum piston usualy means trouble with heat above 250 F'.
For me that is 50 F' hot and I get all the power in 200 that others get at 250. so you probubly need to tune properly or add fuel to the mixture.


Got this off from another forum, is this guy telling correctly?
I have those dark brown deposit on the piston head while my pipe still spitting fuel from stinger, and the car not very fast.
Is that caused by too lean..?

Try increasing rear droop a little to get the weight to the front while off power or braking.

Black deposits over the piston can be caused by several factors.
- Too much oil (castor oil) on your fuel.
- Too high compression chamber (run at low compression).
- Too much heat.
- Too many gallons trhu the piston (this shouldn't be your case).
