Thanks for that word because it's apropos that the engine is idling and
surging periodically.

I don't think either of these California engines have an idle mixture
screw, as the engines are only about three or four years old, so it must be
the clogged passageways of the fuel passages.

I guess, in that case, Seafoam may be the trick as someone suggested.
Do you concur?

Or would you just run a few tanks of fuel?

Â* I'd disassemble the carb and clean it *thoroughly* . The problem is ,
for Seafoam to do any good it must reach the goop that's causing the
problems . If the passage is plugged ... the Seafoam can't reach the
clog . Ultrasonic cleaners sometimes work . Fine stiff wire (along with
cleaning solvent) *always* works .
