Question about Troy Bilt TB4SC 25cc 4Cycle 150 MPH Gas Powered Handheld Blower

Open Question

Blower runs at High RPM only if you loosen the gas cap. Not many hours on this so I am a little irritated that this is even a problem!

I can't start my home lite 26b blower


Mike if the Blower wont start, it's not the High/Low Jets.
They only adjust High RPM running and the Low helps the carb transition from Idle to High rev.
Ethanol gas is a carburetor destroyer... Also, it eats the gas lines .

Sthil bg 86 blower prime bulb work but blower dies try prime again nothing it put pressure in tak


It could be starving for gas at high rpm.
Check the plastic gas lines between the gas tank and the carburetor.
Replace if even the tiniest crack.

How do I adjust the carburator on my Stihl BG55 leaf blower


You can adjust the carb by turning the screws counterclockwise, the H high speed screw is the one closest to the Air Filter and the low L is closest to cylinder (Motor) Change your spark plug first, then run it at wide open throttle and slowly turn the "H" screw counterclockwise a little at a time if it blubbers then it is too far out (rich) so take it the other way till you reach peak R.P.M. s -then back it out opposite way till the sound of the R.P.M's just starts to drop and High speed is set. the low speed is adjusted at idle to where there is no hesitation when you pull throttle open, keep trying till you get a good acceleration with out hesitation, and you are good to go!

Put a new carb on my stihl 400 backpack also a new fuel filter and air filter starts great and runs at full speed and then the rpms drop can bring back to full speed but will drop again no fun blowing


Lucy, the problem is that you have a blocked tank vent/ gas cap. Try just loosening the gas cap,just a crack not even one turn. You are bypassing the tank vent. Now start it and see if it runs longer with out boggind down.If this fixes it, you will need a new gas cap.

Let me know

I have a new echo PB250 Leaf blower and it will not keep running. It starts fine but shuts off after a few seconds.


sounds like a dirty carb, dissamble it and rinse good with carb clean, be careful when taking the top off it that you get it back together the same spray the white center good and all little holes good. then reassemble, also try to loosen your gas cap maybe first before cleaning carb, you might have a plugged vent in the line coming out of the tank. Good Luck

Does not run at full speed unless choke is at 1/4 setting. I checked the air screen and it is clear. I replaced the gas with new fuel 50:1 mix.


its a blocked carb or filter
clean out all the fule pipes and filters
"""even the one in the fule tank on the end of the pick up pipe""" and retune carb when starting up again
ps,, iv never liked running on a 50:1 mix?
i do 40:1 if it smokes a little ,,,,,its got oil in it!

Leafblower shuts off


Yes. Your gas cap is clogged.Try this: The next time you run the blower, and it starts to die, loosen the gas cap. It should start to run again, then you know that it is the gas cap.
