My echo blower keeps fouling out the spark plug, what usually causes this to happen?

I'm sure someone has had this problem and knows what usually causes this to happen. I could really use some advice on fixing this problem.

Exactly what I was thinking.

Too much oil in mix, or carb is running rich, or your not running it at wot enough.

O.k. Now ya got me wondering. I didn't quite use up the last of my mix in a 5 gallon can. I added one of the lil thingys of oil for a 5gallon and only put in 4.3 gallons of gas. Will this affect anything?? Thanks

I run 4 oz. to a gallon, and that's real rich. Another thing to consider, is make sure you took your spark arrestor screen out.

Which blower model are you talking about? I run a lot of units big/small and have not had the problem. I assume you are using Echo mix?

Maybe a dirty or clogged air filter would be my thinking. Its making your mixture extra rich because its not getting enuff air?????

That is a good place to start, along with making sure the air filter isn't dirty or clogged with fuel.

yea I have another pb 403 and have no problems with the mix I use 3oz to a gallon. The air filter seems to be clean. Should I mix less oil in the gas? Everything else seems to run fine. Its only a few months old by the way.

You might wanna empty your fuel container and start over mixing the fuel/oil exactly like its supposed to be mixed. Also, empty out the fuel in the unit and start over there too (now'd be a good time to change the fuel filter too).

Also, are you putting in a new spark plug or just cleaning the old one?

I would say that if you have the right plug in there then it may be a fuel/oil mix problem.
Switch to a synthetic 2 cycle oil of your choice and also take the spark arrester out and clean it if it is full of carbon.
My own experience shows that 2 cycle mix of Amsoil and gas at 100 to 1 gives me unreal performance and no fuel related problems. I have run that mix in ALL of my 2 cycle equipment for 8 years with ZERO breakdowns.
Petroleum based oil has to be burned out at high rpm and heat to dissipate but even then it has a carbon residue that eventually causes problems. Give a synthetic a try, I think that will solve lots of problems. Good Luck.
