Question about Echo Gas Blower 135 MPH390 CFM Blower PB250

Open Question

Gas back blower won't hold steady speed, runs then bogs to idle for a few seconds and then runs again, bogs etc. Sometime it will hold about 1/3 throttle for a while but eventually bogs. Any suggestions.

SOURCE: echo gas leaf blower bog down

Likely dirt in high speed needle valve(H); could be leaky fuel line(air leaking in), plugged fuel filter, pinched fuel line, etc - anything restricting flow of fuel. Likely, you aggravated an existing problem by cleaning the air filter which would have been providing some choke effect if it were partially plugged.

Turn adjusting screws in all the way "gently" until they seat. Not too hard or you will damage them. Turn out 1 1/4 turns on both will get you in the ballpark to start it up. If it starts, let it warm up without going to wide open throttle for an extended period. As it is idling, turn low speed screw in until it starts to want to die down, then turn back out a little at a time until it starts to bog down, then turn it back in to the center of the two bogs (at the highest point of RPM). Throttle it from idle to WOT and it should be a steady rise in acceleration without bogging down. If it does bog on acceleration, turn the Low speed screw counterclockwise 1/8 turn at a time until bog goes away. For the high speed it is critical that you don't lean it out too far. Hold the throttle at wide open and turn the screw counterclockwise until it appears to run really rich. (Blurbs like a four stroke). Then turn the screw back in while holding WOT (wide open throttle) until you get a smooth sound with a bit of blurb every couple of seconds. Hard to explain in type rather than showing it in person, but it will get you in the right direction. I'm wondering why you are trying to adjust the carb in the first place...... If there is an issue that makes you think an adjustment will fix it, try the method above. If the adjustments don't work, or you have to adjust them A LOT, you may be in the realm of a carburetor rebuild. Be sure to check the fuel line, fuel filter, and depending on what model saw you have, the carburetor boot for splits or cracks.

Ttr90 bogs down at high rpms


I have a ttr 90 that idles well but bogs down at full throttle. Carb is clean and has new pilot and main jets. Seems to run slightly better with intake off. Which leads me to believe the mixture is rich. No adjustment on carb. Stumped?

Drive cycle


Here is the OBD2 emission system drive cycle test procedure.
Engine coolant temp must be below 70c (158f) before starting the engine for either the first or second trip
The fuel level should be less than 1/2 full
First trip:
Start engine, idle for at least 1.5 minutes
Drive 3 minutes, hold b/f schdl: 1.5-2.0 msec, selector lever "3rd" eng rpm 1,800-2,000 A/C switch:ON Hold the recommended b/f schdl range. Allow road speed to vary as necessary.
Drive at 55-65 mph for 1.5 min b/f schdl 2.0-3.2 msec, selector lever "5th" Engine rpm 2,200-3,000
IGN "off" for at least 10 seconds (not more than 5 min)
Dive at 50-60 mph for 3 minutes Selector lever "4th" keep engine speed above 3,000 rpm Allow speed to vary if necessary. Do not decelerate for more than 3 consecutive seconds. A/C switch ON.
Drive at a steady state cruise of 53-58mhp b/f schdl more than 1.8 msec selector lever "5th" eng rpm 2,400-2,600
Downshift to "4th" and decel more than 5 seconds without breaking, then idle for 1 minute.
Drive two minutes b/f schdl less than 2.0 msec Accelerate to 41 mph, decelerate to 34 mph, accelerate to 41mph. Do not completely release the accelerator. A/C switch off.
Idle 1 minute in park or neutral
Drive two minutes Steady state cruise at 31-44 mph. Selector lever "4th" A/C switch OFF. Hold the accelerator pedal as steady as possible. Allow speed to change if necessary.
End of first trip. Turn the key off the begin the second trip.
Second trip:
Start engine, idle for at least 1.5 minutes
Drive 3 minutes, hold b/f schdl: 1.5-2.0 msec, selector lever "3rd" eng rpm 1,800-2,000 A/C switch:ON Hold the recommended b/f schdl range. Allow road speed to vary as necessary.
Drive at 55-65 mph for 1.5 min b/f schdl 2.0-3.2 msec, selector lever "5th" Engine rpm 2,200-3,000
IGN "off" add four gallons of fuel
Dive at 50-60 mph for 3 minutes Selector lever "4th" keep engine speed above 3,000 rpm Allow speed to vary if necessary. Do not decelerate for more than 3 consecutive seconds. A/C switch ON.
Drive at a steady state cruise of 53-58mhp b/f schdl more than 1.8 msec selector lever "5th" eng rpm 2,400-2,600
Downshift to "4th" and decel more than 5 seconds without breaking, then idle for 1 minute.
Drive two minutes b/f schdl less than 2.0 msec Accelerate to 41 mph, decelerate to 34 mph, accelerate to 41mph. Do not completely release the accelerator. A/C switch off.
Idle 1 minute in park or neutral
Drive two minutes Steady state cruise at 31-44 mph. Selector lever "4th" A/C switch OFF. Hold the accelerator pedal as steady as possible. Allow speed to change if necessary. I especially like the part where they want you to add four gallons of fuel. Not three gallons, not five gallons, four gallons. Gotta love those Nissan engineers. ...and of course they state that if the trace is not followed exactly (i.e. you botch the acceleration/deceleration) you have to start all over again from scratch

My MAzda 2003 MPV ES.The evap and EGR still incomplete, need reset on the monitor- drive test; everything else passed the smog. no codes show on scanner. FEw months ago, I chage the battery, but I was told...


Here is the procedure for allowing system to run each of the separate mode tests.
EGR : Start engine and warm up completely. Make sure all electrical loads are off (A/C headlights, blower fan, and rear window defroster) Accelerate to between 49-57 mph and hold a very steady speed for 1 minute. Decelerate to a stop and turn off engine.
EVAP : Ensure Baro pressure is 21.3 inHg or higher, Intake air temp is 41-95 'F, Fuel tank level is between 25-75%, Battery voltage is 10.9-14.6 volts. Start engine and idle for more than 10 seconds then turn key to off. Leave vehicle to sit for 5 hours or more. Start engine and race to 3500 rpm to warm up completely the idle for more than 15 minutes. Accelerate and then drive vehicle at very steady speed between 40-50 mph for more than 5 minutes. Stop vehicle and turn key to off. Leave vehicle undisturbed for 20 minutes or more.
When I say steady speed in the above, try to keep dead on to a set speed to help ensure the test is run. Especially for the EGR as this is when the test will be performed and if speed/rpm is not very steady then test will not be performed. The Evap test will be ran during that final 20 minute or more sitting period (or should be anyway).

Pb-413h echo back pack blower bogs down when throttle is applied , idles fine .


This is usually caused by one of two problems. First, the exhaust may be plugged. Pull the screws out of the small screen in the exhaust and wire brush the screen. Reinstall and try again. I had one where some bee's built a nest in the exhaust, no tcommon though.
Second, teh fuel pump in the carburetor may be on its way out. It may provide enough fuel to run at idle but not at high speed. You may need a carburetor rebuild.
Good luck!

Dies when i give it gas


Sounds like your carburetor either needs cleaned or the needles need adjusted. Try turning them just a bit and continue trying to accelerate the engine. If your carb has adjustable needle screws, one will be the low speed adjustment and the other will be the high speed adjustment. You'll know when you have the right one when the motor starts to run just a bit better after adjusting the correct one.

Envoy 2004 idle speed


Hi
your problem seems very easy :) hope this one work with your envoy. Just buy AC DELCO carburetor tune-up conditioner.

How you use it: engine running , AC off please

1. detached the big black airflow hose which is attached in the mannifold of the engine block.

2. ask your friend to step on the gas pedal and set the rpm steady in 2000 rpm only.

3. then spray vigorously in 8 seconds the inside circle opening of mannifold while your friend steady step on gas pedal with steady 2000 RPM only.

4. after you spray, let your freind continue on gas pedal with 2000 rpm for 15 more seconds.

5. attached back the airflow big black hose to the manifold and you are ready to roll with your AC on.

if this one doesnt work, please scan your envoy by scanner called TECH II. and find out.
