Everyone. I need some help with my hyper 7. I cannot figure out why the car bogs down everytime I slow down or stop. The car runs great once it is opened up, but the low end is horrible. I have the hyper .21 4 port and it is used. If I pick the buggy off of the ground it reacts perfectly. Only bogs when there is a load on the engine

Could this mean that the engine is shot?

Is is something with the clutch?

I am not new to the hobby, but I cannot figure this out. Hopefully someone will be able to give me some ideas.

Thanks.

When you pull start it does it have good compression ?
Is the clutch engaged at idle ?
Have you adjusted the your high and low fuel settings?
you didn't give much information about what you had tried ? or done yet. There is a lot of things that it could be.

It seems to have good compression when I pull the cord, but it is easy to pull.
The clutch is not engaged at idle.
I have tried adjusting the high and low needle. It runs great mid range to wide open, but is running pretty lean 260degrees to make it run like that.

I have rebuilt all of the difs, Checked all of the drive shafts and dif boxes. Made sure the brakes are not binding etc.

I did get an extra motor from Nolec5 and I am going to try that this weekend. If his motor does the same thing, then I will know that somethign is wrong with my motor.
