Well Took it to the lake today and got it to run. <br />it would do 5000 rpm at WOP and then die down to 2500-3000 rpms WOP and then speed back up to 5000 rpm.<br />Then it would die and then start back up and act real sluggish and do 2000 rpms and then die again<br />So I would start it up and it would run at 5000 rpms at WOP.

hi, it sounds to be the same problem as my DT65:<br /><br />In my case it was the carburator-set, rebuilt them or clean all carbs very carefully from coals, etc.<br />it goes back to 2500 rpm, because there is an electrical insurance in the cdi, which should prevent dangerous faults from your engine.
