My car started to stumble tonight.It would drop about 200rpm.But it starts great and runs just fine.But at idle,it drops 200rpm,you can feel it.Like the car got hit.
I had a power valve go bad before.It felt alittle like this now.Do you think it's another blown power valve.I had a hard time starting it yesterday.But I got it started and seem to run fine.But I didn't drive until tonight.

Please let me know what you think.

Thanks

Define stumble Ron.
Off idle tip in?
You said you lose 200 RPM. When?

It was only doing it at idle,either stoped or rolling.At least I didn't notice it any other time.
It was more like it would just CUT out.I'd stop and the car would be fine,then bang it would 100-200rpm,bounce back.And it would do that very so often.But drive away just fine.It did seem to drive like it was alittle rich at first last too?

Thanks

You probably need to fool with the pump shot delivery. Either a cam change is in order or a 50 cc pump kit may be neccasary now.

I'm not questioning you,but would those things make it cut out like that?
You could feel the car like it was hit.

I have an orange cam in now,and it's on the #2 hole.
