Need tuning / plug choice help for Pacific Northwest US

---------------------------------------------------------
This is going to be long...
On my EHP ported Redmax I got from Kevin, I am having problems
with "wet fouling" the plug. When I got the saw, the Bosch WS5E
plug looked nice and dry, kind of like a combination of #11 and
#13 on this page from the spark plug thread:
HTML http://www.dansmc.com/Spark_Plugs/Spark_Plugs_catalog.html
After just a couple tanks of gas, the plug started to exhibit
wet fouling that looks a lot like #1 on that page. I leaned out
the H jet a little bit, but it didn't seem to make a difference.
The plug died on me yesterday and I put in a new Bosch WSR6f
(made in China, not Germany, though) and the saw ran good for
the rest of the afternoon.
I pulled the plug after I was done and it was also wet fouled.
This makes sense from the perspective of it being a higher heat
range plug so it's not self-cleaning (according to that page
above), but it looked exactly the same as the WS5E did as far as
being oil fouled.
I am going to get more WS5E plugs from Northwood Saw since
that's what Kevin ran and they are one level cooler.
I am also going to lean out the L jet to see if that helps.
Other variables are that Kevin runs 32:1 and I am running 40:1,
so I'm automatically a little more rich. My fuel oil is Maxima
K2 mostly because it doesn't stink like a lot of other oils and
it has a good reputation.
I have read about humidity, temperature, elevation, etc all
playing a role in a saw's tune. I am 30 minutes inland from the
Puget Sound, so I am not dealing with salt-water humidity. It
rains a lot here and is usually very humid, especially in
winter. I cut on days where it's cooler and not raining, but
humidity is still high.
So if anyone has other advice aside from leaning out the L and
running a WS5E, please let me know.
Thanks,
Cameron

Sounds like you must be really rich. Never seen the plug wet in
that saw running a bosch 5 6 or 7 in it.
It was fat when it left here with 32:1 Klotz Original 100%. I am
betting it is even fatter now with your mix and location.
Any idea what rpm you are turning WOT out of wood?
If you cant tune by ear and checking plug method. Maybe use a
tach or someone that knows how to tune a saw correctly?

I cant remember is there a half choked setting? Pull choke out
pop and then half till warm and then push all the way in? I
cant remember on this saw. Maybe forgetting to push the choke
all the way in and off? I've done this on some poulans in the
past.

There isn't really a "half choke" on this one. I have to be
very careful to not push it in all the way after the "pop" and
once it starts, I push it in right after I blip the throttle to
go into low idle.
I don't know the RPM it's running. I did lean out the H jet and
it sounds good at WOT with a little roughness, and cleans up
nicely in the cut. I think the L is still too rich even though
I leaned it out a little bit.
When I tune the L, I usually aim for the midpoint between too
lean and too rich. I think that I will aim for just a little
bit before too lean on the L and see how this plug holds up. I
am cleaning the plug off after each use to keep it from dying
early. Going to order 6 WS5E plugs today, too.

Why messing with L ? You having throttle response problems or
idle problems?
H is the in the cuts. Go for 14K to 15K WOT Art said he went as
high as 15K. Happy medium 14.5K.
I sent it out 13.8K from here.
Take me a min to set that for you, wish I could help set to your
area and mix.

Yea, I need to just get a tach. As for the L I was thinking
that even if my H is ok now that I adjusted it, if the L is too
rich then it could contribute to the wet fouling problem. I
read some threads where that was mentioned as something to watch
out for.

Hopefully someone more experienced in this with what your
thinking steps in on L thing. Never had that problem.

The WSR6F spark plug is a extended tip 2 stroke design whereas
the
WS5E spark plug is a non-extended tip used in a racing saw where
the other spark plug may hit the piston.

From my understanding the WS5E was a coller plug some of the
alky racers used. I used them and used them in my woods ported
saws too. The redmax 5000 can use the stock plugs, no clearance
issues with piston.
