Dan, I just came off of that same problem. You may want to richen up the lsn by 6 hours at a time till that problem goes away. You will eventually have to compensate with a lean per hour on your hsn and mess with the idle needle. It took 12 hours on the lsn for mine to go away and I had to lean the top by 2 hours and mess with the idle.

So what i think it comes back to now is either pipe or furel tank. Has anyone had any similar problem with a tank?

Cheers Dan
One more thing to check. I had the same problem that took me out of the A at a state race. Check the screw on the top deck, under where the throttle returns to idle. This screw will back out if not tightened down. Mine prevented the throttle to return to idle and I kept blowing the corners because I couldn't slow the car down.

Thanks for the replys guys as far as tune goes i have tried everything even to the piont where the lsn head is out past the ball for the coupling. What i originally thought it was was air leaks on the motor so everything has either been changed or sealed up even the head button as i thought the glow plug wasnt sealing properly. I have replaced all fuel lines and tried 3 different crabs.

Sohlman, no i dont have a pressure chamber but was thinking about getting one, but i dont know the what they are supposed to do, can you fill me in?

Cheers Dan

However, I lose so much time/distance at the end of a straight going into the turn. The guys with regular diffs just out brake me. How do you guys counter the effects of the front one-way? Or is it I'm just too worried about going into the corner too hot and I should just have confidence that the car will just stick? BTW, I've got the car setup according to the setup sheet but with 30,000 wt diff oil.
My suggestion is to use the front diff. Our track infield is too tight for the one way, espescially if you are not use to a one way.

Btw, racing this Sunday. Stop by, maybe can help. Still trying to dial in my 4

A pressure chamber acts like a larger, more powerful fuel pump...without having to spool up lots of fuel tubing between you fuel cap and pipe. It keeps the tank well pressurized for better fuel flow.

Mugen Seiki Pressure Chamber Set #B0116

I hope you work out your engine issues.

wassup RoyU! Yeah, that's what I was thinking too. Unfortunately, lhs don't have the parts to make a diff. Someone suggested to use the blue brake pads since it bites harder but more gradual. I think I might try that. Since I never raced with a one-way, I might as well try atleast one race with it. If I don't like it, I'll switch to the diff.

Yeah, I might actually race this sunday. The only thing I gotta do now is decide what shore tires I wanna run.

I would love to come down, but it's not in the cards this year. Hopefully, my US teammates will bring home the championship for Mugen.

Start out with 40s. True the front tires 2 mm smaller than the rears if you are using the 24t outside mid pulley.

YBSLOW will probably disagree with me, but running a 25t pulley with 2mm split with give a noticable on power push. That setup will give front underdrive meaning on power your front tires will be turning slower than the rears.

Bottom line, is you can test for yourself but I would not use the 25t pulley with a 2mm split. Use the 24 as was suggested.

the car turns in better and i dont find it pushes atall i do some times run it with 1mm and with the 24 it wreaks the front drive, this is on a short track on a big track 24 works ok but i still dont like it.
