A friend dropped off an ETQ TG-3600 he found at the curb and asked if I could get it running.
Tank and carb were full of water so I cleaned everything up and generator surges no matter what I've tried. It surges on idle and under load.
Here's whats been done.
gen model ETQ TG-3600
engine model ETQ-200
Engine family 5ETQS.1962E1
196 cc
Removed tank and am running fuel from a bottle.
Cleaned OEM carb thoroughly including Main jet, pilot jet, needle etc.
replaced all 3 gaskets between intake and air filter
tried adjusting pilot needle
sprayed carb cleaner on all mating surfaces to see if surging stopped
drilled out pilot jet
drilled out main jet
checked spring on governor arm was removing slack
Tried another aftermarket carb...still surges
I'm at a loss at what to try next. many thanks to those who reply.
