Hi Restrob. Yupper i did and it had partial restriction so I did an
old trick I learned long ago from the 2 cycle guy I worked with and set
the muffler in gasoline and set it afire and it cleared out the partial
restriction to a full flow again. The carb is a Walbro I do not
recollect the number but if it helps here is the link to a carb list
and it is for a 154 SE

Year of production 1984

Hi Restrob, I had that carb completely apart and saw no screen. I
replaced it's needle and arm and diaphram and on the bottom I replaced
the gasket and the floopy type diaphram that opened and closed ports
and saw no sign of a screen. I looked and figured there had to be but
did not see it anywhere and since the overhaul she is somewhat useable
but lacks horse and her performance is lousy and needs twekaing all
the
time. I did start at 1 turn each screw for starting point and opened
it from there. Like I said I have overhauled all brands of car carbs
over the years but this timy little carb was new to me and if there is
a screen hidden where is it ??




Hmmm,
It should have been located under the diaphragm above the fuel inlet
needle (which is located in the center of the carb. body).

Can you post the brand carb. and the number stamped in it ?

Have you checked the spark arrester screen in the muffler ? These will
clog up from the fuel mix restricting exhaust flow and could cause as
you describe also.
