You're doing a fine job of trying to isolate the problem and learn at
the same time.
This carb is NOT the easiest to understand. *It is an amazing
design...but it's almost like they got one person to design this...and
them put him back in the asylum.- Hide quoted text -

Thanks. *Designing carbs has to be one of the black arts. *Trying to
understand them without all the documentation is a real challenge.

I'll just keep plugging along. *Since I can start it and keep it
running at 1/2 choke until it warms up, then go to no choke, I'm good
for the short term.

One more thing I can think of is, if the plug is the right heat range
(correct plug number) *and the gap is set properly.

As to carbs.. it's fun when they run and you still have ten parts left
in the kit box :-))



Again, my thanks to everyone here for their input. *When I get this
fixed so I have full power and it starts with one pull as it did when
I bought it, I'll post whatever I found.- Hide quoted text -

I'm using the spec Champion spark plug at spec gap and I used 2
different spec spark plugs (the last is brand new).

I'm now assuming and testing for a carb fuel flow problem. I've
ordered a new pick-up tube and a spring for the idle screw just to be
on the safe side. I have turned the idle screw to several different
setting with no starting improvement. I'm going to pull the carb
today for the last time and take off all the rubber parts and soak it
in Berrymans Carb Cleaner (I have a gallon can with a screen tray for
dipping). I did use spray carb cleaner a week ago that "seemed" to
help. So I'm thinking a 3-5 minute soak should get any crap and
varnish that might still be in the circuits.

As for old gas, I have removed, drained and flushed the tank already
and adding freshest gas provides little improvement. The leaf blower
seems to run better with 2-3 ounces of Berrymans Carb Fluid mixed with
a full tank of gas. Even with the carb cleaner fluid it still takes
2-3 starts before the engine keeps running on 1/2 choke and then after
9-12 minutes I can turn the choke off completely, but the engine does
run a lot longer than 2 weeks ago.

(I have been using WD-40, but I haven't needed it the last couple of
days. WD-40 doesn't make starting that much easier, but reading about
all the down sides of starter fluid in the earlier posts makes it
easier to accept a little harder starting using WD-40 when I have to).

Best regards,
