Chainsaw Repair

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:

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

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.

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.

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

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.
