Echo PB-413H bogs down

My echo pb-413 bogs down at full power. I thinks its a mixture problem but my adjustments made it worse. L and H adjustment screws have
limiter caps. Is there a way to get it back to factory settings?

    Thanks for the info but its only 6 month old and has maybe 4 hours on it. So I am at a loss.

  • ry_spider1 Jun 08, 2009

    I will try that Thank you very much.

  • ry_spider1 Jun 23, 2009

    I did try to adjust the H&L now I get good power if I leave it almost choked all the time. So I guess its still a mixture problem.

  • ry_spider1 Jun 23, 2009

    Thank You very much I will try it and see.

  • ry_spider1 Jul 02, 2009

    I finally gave in and replaced the carb. Runs fine now. I guess these carbs. are preset as I did not change any settings. No limiters on adjustment screws either. See what happens. Thanks.

There is no point in messing with the setting until you clean the carburetor. it sounds like that is your main problem. Or you may need a new carb. kit, depending on how old the carb. guts are. If you need tips on carb., just let me know.

    This seems to be a common problem now with new equipment. I've been seeing a lot of folks with this same complaint with their new small engines??? My only suggestion is that you make sure that your gas mixture is correct, and fiddle around with the H & L adjustment screws. They don't adjust as much as the older carburetors do, and they seem to be more temperamental.

    Then you have a dirty carburetor. When fuel sits for long periods of time, it has a tendency to gum up the carb. This is why you should use a stabilizer in the fuel if you are not going to use it for a season or two.

    You
    will need to disassemble the carburetor and spray
    with carb.cleaner. Make sure the small screen is free of debris.
    (Should be able to see daylight through it.)

    Use a Den Tek Brush, (http://www.drugstore.com/products/prod.a...),
    to clean the small portals in carb. These portals can
    become blocked. Reassemble and start.


    If you need further assistance, just let me know.

How do i adjust the carb on an echo blower


Not sure what carb you have..You should be able to see a spring loaded air/gas adjustment screw on the carb..once running turn clockwise until motor starts bogging down then the other way until it does the same..keep adjusting back and forth unti it runs smooth..
you may have another on the bottom of the carb bowel..do the same with it...if this doesn't work needs a rebuild kit..good luck..

Echo pb-620st will not crank


Simply use a srewdriver to adjust the mixture screw. Its located on the carburator. Clockwise is lean, counterclockwise is rich. If you can get the thing to idle, let it warm up first. Adjust the mixture lean until it just starts to sputter, then adjust it rich 1/2 turn. Test full throttle, if it sputters, you can adjust the mixture a little more rich so that it runs good at full throttle.

I would suggest steering away from investing in 2 cycle engines for a pawn shop, unless you can see them running. These little engines are very picky and they only run well if they are in good shape. If you cant get them to start easily, there is probably a lot of internal wear/damage and these engines are hard to find parts and are not cheap to fix.

Bad investments would include 2 cycle leaf blowers, trimmers, chainsaws, boat motors, and motorcycles that do not start easily. Believe me, they are a headache to fix.

ECHO PB-250 blower new used one time carb.needs adj.can this carb.be adjusted


Your machine has a rotary-valve diaphragm type carburetor. These carburetors typically only have an adjustment for the IDLE speed with an available option to control the main jet with an adjustable mixture needle.

http://www.echo-usa.com/Products/Blowers/PB-250

Here is the info on the Zama rotary-valve diaphragm carburetor.

http://www.zamacarb.com/prodlist.html#RB

Some have a small adjustment needle in the center pivot of the rotory part, under a brass plug...but most have nothing. Many end users and techs are complaining about the non-adjustable carbs. They are made this way to meet the more stringent EPA emissions codes that are getting tougher each year.

I have an older echo blower. just had it tuned up and adjusted and still running poorly. just wondering if it is my fuel mixture of 25;1


25:1 may be too rich a mixture. Clean your spark plug well. Then get some good synthetic 2 stroke oil and try a 32:1 mix or a 40:1 mixture. Here is a fuel mix chart for you use.

Air cap on ignition module Echo PB-413H blower


The air-gap between the ignition coil module and the magnets of the flywheel is a close tolerance. It is adjusted to about .010"-.012". This is approximately the same as the thickness of a standard size business card. I double the cover and let the magnets on the flywheel (lined up with the coil legs) pull it in tight 9compressing the paper card) and then tighten the adjustment screws. The screws have been known to vibrate loose and the gap would be lost. You can use threadlocker on the screws (optional) or just tighten them down well. Too large an air-gap is bad, but the closer the air-gap, the stronger the spark.

Echo pb-413 leaf blower not running properly


It doesn't appear to be getting enough fuel. Unscrew the "L" and"H" screws about an 1/8 to 1/4 turn. Also at the end of the season run it completely out of gas and you shouldn't have anymore carb problems.

Please rate if this helps-
