My son just bought an Enticer Ii 410CC, we cleaned the carb like we have done a 100 times on other enticers.

One its cleaned and put back the moment we start it the machine revs wide open and we need to shut it off asap.

The idle is backed of the butterflies work fine I just don't get it.

We took it apart to double check and one again 1st pull it runs wide open.

Any ides?
 

What happens when you flip the choke on when it is running? If the revs drop back down then you have a lean condition possibly caused by a real bad air leak. There are not many areas on the ET410 down stream of the butterfly for a bad air leak other than the crank seals.
