well,
the front bearing leaks now and then, the engine run too hot when its rich... while the engine was in the car with the pipe conected and glow plug, i was able to turn the fly wheel by appliying a little force.
however, if I turn my engine side ways, not that its off from the car and it hold it from the flywheel and let the compresion keep the engine from falling, it stays vertical... I am not sure if I am making sense... I can post a picture if you want... (keep in mind there is still a glow plug in there.
maybe i just need to get a new carb and bearing... ? (the card is way to big.. i hate it doesnt fit in the car)

I would not know if you can write the engine off based on your description. If the engine has AAC sleeve, I believe it will be easy to turn the flywheel even when you have the plug in.
I do not know which Sirio version you have. The EVO II seems to have taken care of the leaking carb problem. I think best would be to get an experienced tuner to check and tune your engine. If possible, try and get or borrow a Nova carb and put into the Sirio. That should eliminate the other variables.

ATTENTION!

I have just ordered a Mugen MTX3 Prospec, it has 08 module gearing. Big question is, can i use my Kyosho RR Evo pinions on this car, the Evo pinions are also 08 module???

Finken... Why would you want to use kyosho pinions on the Mugen??? Alot of cars use .08 gearing now, but that does not mean that there pinion gears and spur gears match... If you ordered the MTX3 Prospec, the gearing out the box is right on and you should not have to change to much after that except to have a few extra's gears on hand... Also the mounting of the gears are different.. What motor do you plan on running in the Prospec??? Great car, great purchase and good luck racing it...

But forget all that . . .
We also have a Kyosho Evo but only a couple of weeks experience with the MTX-3.
From this short experience I'd say the Mugen pinions will be good for about ten race meets and we already know the Kyosho ones will last about ten minutes.

It will work on ANY clutch gearing and on ANY cars that has the Centax clutch.

[B]You may be able to but there is a difference in diameters between the Mugen and Kyosho pinions. Also remember they pull some sort of fudge in order to be able to have different tooth counts on the same diameter pinion.
Yes this is true, there is also 2 other very important issues here.
1) the mesh on .8 is very fine this is basically how the manufactures were able to create .8m's, shrinking the teeth down in size allowed more teeth on the pinion... This results in a very fine mesh, that needs to be correct from go.
Also the shape of the teeth vary from one manufacture to the other. When such a fine mesh is required and if you mixed say mugen and Kyosho its possible they use different shape teeth and this will make setting the correct mesh very difficult.

Sounds like you guys don't play around much with gearing or run on differing tracks frequently......My personal opinion is that having a wide selection of gearing is VERY important for any racing vehicle.....especially one where the tire-size changes like the foam tires we are racing on.....

Clarification.....will work on Centax II clutches (HPI, MTX-2...etc).....will NOT work on Centax III's like the Serpent 710 (and maybe G4).

Need some info...Switching to MTX-3
Okay, I am getting ready to give up the NTC3 and get the MTX-3....
Goodbye SAE, Hello Metric....
What drivers do I need for the screws? What size is the nut for the wheels? I want to order my tools and allen drivers from the web before my car arrives.
Also what are the most common size and heads of screws? What should I have spares of?
Thanks!!
