Thank you ! Took me a whole three minutes to do. Worked great . Runs smooth and powerful again. I found an screwdriver from an eyeglass kit fit perfect

[@dmmjq2]

Perfect.. thank you I was wondering where that stupid screw was...lol

[@PatrickBarton]

Mine was doing that but I changed the fuel fuel filter and it worked great again. Appreciate your videos brother. You were a big big helping when I needed to adjust the carb on my ryobi 1838 chainsaw.

[@smallengineguys]

The fuel lines go bad alot.

[@happyman9612]

Awesome. Thank you! I just bought one of these used and it's a little boggy sounding.

GRACIAS POR SU VIDEO...ME ES DE MUCHA AYUDA....EXELENTE VIDEO

[@ShortbusRejects]

This blower has two adjustments a high and low screw the other is a star drive down the center of the carburetor barrel

[@kendalwilliam3980]

So there is actually 2 set screws one is located where shown in video, and there is one on top of the throttle barrel I believe it’s high side and the one under the gas bulb shown here is low side if I’m not mistaken..

[@smallengineguys]

one in barrel is a pain in the ass so i dont bother with it ever

[@jackschmac]

I used a coarse drywall screw to remove the plug. I would imagine a fine threaded one would work too.

[@shifttransformations6597]

Awesome, video on my friend help me out so much. Couldn't figure it out, i just cleaned my carb out thought everything would be running well but it was struggling and bogging out. Did exactly what you said? It's running strong as an ox..

[@smallengineguys]

I've got the same blower but mine has a brass fitting in that hole I watched a video of a guy that took a drill bit and got his out with a drill bit so I tried that and I drilled down the brass fitting as far as I could go and it still won't come out to get to the screw to adjust the dang on thing

[@smallengineguys]

ummm never seen that. usually if you see brass ur looking at the screw. aftermarket carbs work well and no plug. i use hipa they are oem spec amzn.to/3CQOGQR

[@brendangair2023]

@@smallengineguys some have a small brass sleeve that they pour the plastic into, it pulls out too with the plug, needle is below.

[@smallengineguys]

@@brendangair2023 ahhhh rhb70. Yeah so I heat up a tiny flathead screwdriver red hot. Press it firmly into the plastic plug hold it very still till cool. I use a bit of break cleaner to speed up the cooling process. After cool turn and pull a little at a time till it pops out. It's a flathead underneath.

[@Dawson6858]

Torch next to gas, you're the man

[@smallengineguys]

As long as it's not lit.

[@davidwismer2707]

It's a closed container, if your that paranoid go back to your bubble@@smallengineguys

[@klink370]

Is the adjustment goal to set the screw so that it runs at highest RPM at WOT?

[@smallengineguys]

Hit highest come back just a touch to the point it doesnt bog from idle to full speed.

[@klink370]

@@smallengineguys Thanks. I didn't have a torch but I was able to heat up a jeweler's screwdriver with a candle and that worked for me although it took three or four attempts, each one moving the plastic out a tad until it finally come on out. Thank you so much for the video.
