I would run a new fuel line because it sounds like not getting enough fuel. If this is a high use unit I have some other things to check.
Thanks for the reply. The unit has perhaps only 200 hours on it at most. Compression is good. Adjusting the hi screw does nothing as turning it all the way in both directions has not effect at all. I did replace the fuel lines, filter, and plug, and of course the new carb, all to no avail. Is there an easy way to verify crank seals are in place?
FWIW, the problem started all at once. Fine one day and the problem the next upon start up. The unit runs normal except for no acceleration. Its starts fine and will not die...just the no high rpm issue.
