SOURCE: I have an Echo 300E

Here it is straight from ECHO:

Link is http://www.echo-usa.com/faqs.asp


A 50:1 ratio with 89 Octane fuel can be used in all ECHO 2-stroke equipment, provided the oil is ISO-L-EGD and JASO M345 FC/FD certified. ISO-L-EGD and JASO M345 FC/FD oil must be used with a mid-grade (89 octane) or premium gasoline in all 1997 and newer engines.
A 50:1 Ratio = 1 US Gal. 89 Octane + 2.6 fl. oz. ECHO POWER BLEND OIL
Echo Power Blend Universal 2-Stroke Oil can be used in all of our 2-cycle air-cooled equipment ever made. You may also use this oil in any other brand of 2-cycle air cooled equipment, but it should always be mixed at the 50:1 ratio whether or not it was a 32:1 or 16:1 etc. machine. This oil is the highest quality 2-cycle oil on the market today. There is no need to have more than 1 tank of fuel for your 2-cycle equipment any more.

Turn on ignition switch, Choke, prime bulb 5 times (or until fuel flows), hold throttle down and pull starter cord sharply until it tries to start, then place choke in mid position pull cord sharply again until it runs then move choke to off when it will allow it.
Also you can go to toro.com then customer care, then manuals and parts then type in model no. and download an owners manual.

SOURCE: I have a Echo PB/251 Gas Blower which I recently

Check the muffler and/or spark arrestor screen in the muffler outlet pipe and also the engine's exhaust port behind the muffler. These are prone to carbon-clogging and the engine cannot "BREATHE" enough to reach full throttle. If all-clear in the muffler, go back in the carb and locate the inlet screen directly opposite of the inlet needle. Carefully pull it out with a pick and hold it up to a light source. If you cannot see thru it, replace it. This is another, (less) common area of obstruction.

Hope this helps,
Dolf-

SOURCE: mb 3200 gas leaf blower will start when choke

The carburetor could need rebuilding or you have some bad gas. I would mix up some 2 cycle oil and fresh gas from the station. I would try the new fuel mixture first.
Good Day.

My pb413T want to run only on choke


Its a lean condition... Its not getting enough fuel. Check fuel filter and fuel lines, be sure to use fresh fuel then either adjust the carb or rebuild it.

Won stay running


Needs a carb adjustment, cleaning, or possible rebuilt. Try adding a little seafoam and running at half choke for about 5 mins or longer this may clean it up nicely. also check the spark plug.

What is the starting procedure?


Start with the choke on full press the fuel siphon button till the lines are full of fuel. pull handle until it tries to start but stops. move the choke to half then start again. let it run for 60 seconds on full. don't move the choke to full or it will stop. Either slow the revs and then put the choke on full or keep the revs high and slowly move the choke to full (to allow the governor to slowly advance with the new revs)

I have an Echo PB-500T blower that won't throttle up. I bought this blower new about 3 months ago. Before this blower I had an exact same blower that gave me the same problem. I returned that blower...


Remove the in tank fuel filter and take it apart, the felt Echo uses on the filter clogs quickly. There is still a mesh screen filter in the assembly so make sure you put it all back together and reinstall the fuel filter into the tank.

The blower will not run steady unless choke is 80 persint closed i had to move choke up and down to acheive this


Hi jwoods733, I think we should start simplest and least expensive first. Sounds like a simple adjustment. I am assuming it starts ok.Turn The high speed counter clockwise(furthest from the engine) about 1 half turn. May have to play with a little one way or the other. This should fix it. If it doesn't replace fuel filter. It is in the fuel tank, fish it out with a wire bent into a u shape. Hope this helps ya.

Starts and idles will not run above idle unless choked. Have cleaned carb multiple times new fuel filter new air cleaner and cleaned exhaust screen new plug. Maybe a collapsing fuel line?


Hi,
Have you tried adjusting the carb? There should be two screws on the carb (hi & Low) turn the hi screw completely until it stops and then start the unit. Let it warm up and then begin to back the screw out until it starts to run smoothly but strong. Once you have it running then put it in full run position (choke) and you should be good.
Good luck!
