It would be plugged so it would have to be removed. It basically moves the jet needle up and down when you turn it. If you choke it partly will it accelerate?

There is no acceleration with partial choking and the muffler and output port are clean. There doesn't appear to be another adj. as I can neither find it on the carb nor in the carb schematic. I'll take a look at the seals this weekend. Could this be an ignition problem? Overall, the unit runs normally re starting and idling and never dies. It just wont accelerate. Thanks again for the help.

That symptom has alway been associated with getting gas. Take the plastic block off that is between the carb and cyclinder and clean out all holes in it and into the cyclinder. You can run a wire thru. Be sure you got good gaskets and they are orientated correct. That hole the I told you to run the wire thru can't be covered by the gasket. Also check to confirm that that spacer has not warped and if it has sand it down flat.

It could be the coil those things are pretty complicated. But I never had one that started a unit yet was bad.

I checked the holes in the block and cylinder and they were clean. I then checked the crank seals and the recoil side was spotless. However, the flywheel side had a small amount of greese/oil residue on it. Could that be the problem?

It could be but doesn't seem likely usually the unit won't start if those seals are out. When the unit is idling you can spray quick start behind tha flywheel to see if it affect the engine rpm. If no affect then it is probably okay...

I sprayed the flywheel seal with starting fluid and the machine either bogged down and then recovered or died so I presume the seal is the problem. My question is, before I replace this seal, is there anything in the area of it that could cause the bogging down or the dieing of the engine when being sprayed with the fluid (thru the straw attachment on the can). I ask because the machine is fairly new from a run time standpoint and the seal looks perfectly in place. Further, my Echo dealer doesn't stock them and says they've only sold 2 this year. The only questionable thing is that there was a little oil/grease residue on the seal when I first looked at it. Again, thanks for the help.

Tough one.....Maybe try putting spray around the carb mounting onto the cyclinder. The spray could have gotten around there. I would agree new units should not have seal out. It is hard to get that flywheel off to get a real look. This is a new carb correct?

jud149 · #27 11-06-2012, 07:58 PM

Yep, new carb.

Well you got to try changing the adjustment needle on that carb. You didn't on the old one correct? Get that dealer to pop those caps off the needles.

As mentioned, adjusting the carb (H), (there is no L adj.), has no effect. The machine runs identical (no acceleration) with either the old or new carb installed. The old carb has a fixed jet which is non-adj.
