Echo Hand Blower PB251

Blower was running rough and hard starting @ end of season.
Work/start great, or work/start like shi!!

Put a new plug in it (fouled/carbon)new fuel & air filter.
new fuel.
Won't fire or even pop like it wants to start.
Any ideas on whats next to look at.
Don't want a $100 bill on a $180 blower

Thing was new last spring, had one a year prior with "zero" issues.

If you spray a little starting fluid in the intake, will it start? My first guess is gummed up Carburetor, a most common problem in small engines.

Have not tried any starter fluid.
I run Amsoil synthetic at 80:1 and 91 octane in all my hand equipment.
Seafoam in fuel can every other week.

Shouldn't be gummed up.
08 model I had ran great and was used much more then the current one on a
daily basis.

You say 80:1 Fuel to Oil ratio, Is that Echo's recommendation? I could be wrong, but that sounds pretty rich to me. You know everything in there is lubricated by the Fuel oil mix, right?

Any way, not much can go wrong with two stroke engine. Do you have spark from the spark plug? Have you tried a small amount of gas straight into Carburetor? How about the run switch, everything check out there? Believe it or not, small engine carbs do get gummed up, flapper valves warp and stick, and varnish builds up inside, esspecially if there is any storage time involved. In my experiance, most running problems in small engines, is Carburetor related.

Just for my own satisfaction I went to Echo's web. I found that they recommend a fuel to oil ratio of 50:1. This tells me you are lubricating that engine much less than the manufacturer calls for. You are thinning your oil by 30 extra parts (that's a lot) They say like, 50 oz. gas to 1 oz. oil, your putting 80 oz. gas to 1 oz. oil, you're thinning that oil the equivalent of 30 oz.. Perhaps you have some special reason to do this, but in my opinion you are shortening the useful life of your machine. Myself, I always err on the side of too much oil, that way, I'm sure everything is getting at least enough lubrication.

You can do what you want, but everything Bearings, Bushings and piston rings are all lubricated by the oil you mix with your gas.
