My saw won't start, I changed out the fuel/oil mix and the plug is wet. I see what I think is a weak spark issue? The saw ran great the last time I used it about a month ago? Thanks.
Maybe you just accidentally flooded it? Pull the starter rope gently half dozen times with the plug out. Spray plug electrode with WD40 then dry with compressed air......or just leave it all sit to dry and try again?
Yes, the advice to air it out by removing the spark plug and pulling the rope is good! Also check for spark while the plug is removed. Kinda like this: Or there is this....
Been through it with the same model saw-- it was heavily flooded because I didn't hear the first burp. I removed and dried up the plug, had the old lady put her finger in the spark plug hole while I pulled and pulled -- about 60-80 times-- with the choke set to run. Then put the plug back in and it started normally. I'm told it's important to have the hole plugged otherwise the saw won't clear. Anyway, worked for me.
It will clear just fine with the hole unplugged. If it's really wet, turn the saw upside down and pull it over.
May I ask what led you to believe you have a weak spark? I only ask this because it can sometimes be difficult to diagnose spark quality without a spark tester. If you're thinking it might be spark you could try checking the coil air gap. Should be about .010", or most easily the thickness of a business card. But, as everyone has indicated above - a wet plug normally equals a flooded saw.
I may have flooded it, back to work in Abq, NM so it will have to sit until I return. Thanks everyone.
When I flood one I pull plug pull rope and let it blow fuel out and spray plug with carb cleaner and or just blow it dry with compressed air. Then reinsert and start with saw in run. If this does not work I do as the second vid in MM post. Basically start the saw with trigger held wide open. It will start pretty easy even without all that I mentioned to do, if it has decent spark.
