I have a HOnda GX390 13 HP on a generator. Has done pretty well for me over the years. Went to run it this morning when power was out. Would only run 20-25 seconds and shut off. Gas flowing to it, gas in the bowl. It had done this one time before but could not remember what I did. Oil level fine. I had just done my pre season oil change etc. and ran it not too long ago with no Prob.

Blasted some 2+2 in it did same. Tried to keep it running spraying fluid in there. No deal. Finally tried grabbing the throttle (spring loaded deal to maintain RPM on Gen., and held it low to see how long it would run at low RPM. Let off eventually and it runs.

Filter shows nothing in it.

Any ideas? My first reaction is to just put a new carb on it and not look back. Best plan or not gonna solve it? One of those things where I really need it to work when I need it.
