Thank you! Wish me luck. I took the carburetor apart and cleaned it put in a new coil pack and spark plug started up on the first pull and ran great for a half hour, two weeks later now it won’t start, seems to be flooding out never knew how to adjust the carburetor until you showed me in your video Thank you

I agree, you are straight forward, clear and understandable. I don't know how I stumbled in here, but I am glad I did
Thanks, mister.

Thanks so much! Simple and concise instructions. I seem to have the most problem with my string trimmers, I will get to adjusting them today after watching this.

perfect manner and simple visuals to follow... great explanations to every aspect of tuning w/o all the confusing tearing a thing apart from the inside out. I've seen so many tearing everything down putting everything together and 'miraculously' the damn thing was perfect... never happened that way for me. thanks for the perfect tutorial. lol i just went to subscribe and i already am! lol

Thank you for sharing this information I watch this video every single time my blower starts acting up cuz I keep turning the low idle screw the wrong way and have to run it all the way back in and start with the one and a half turn counterclockwise

you made getting those caps off look too easy LOL followed this procedure today on a McCulloch backpack blower, with success thanks to you!! automatic subscribe!! quick question... can the return line be too long?! cut mine a bit shorter than the filtered line, and i dont want it to interfere. think i should shorten it?? sure is causing some commotion within the tank. thank you for your efforts and time!!

Can i adjust my stihl mistblower thesame way?

I got one for you. I own a STIHL BR380 blower. Even though it’s 11 years old the hours are low. I only use non ethanol gas and synthetic oil. Last week after full throttle use of about 30 minutes it lost power (rpm’s dropped). I took off the cruise control and it idles fine. Shut it off and it starts fine but will not rev up to high rpm. Once cold I start it up and it does the same thing. Only difference is it only takes 2 minutes to act up now. I have done the following. Cleaned the spark arrestor, replaced the spark plug, air filter, fuel filter, carburetor (OEM), ignition coil, and fuel lines. Compression is 127 (checked it right after it lost RPM). I also removed the filler cap thinking the vent was clogged. No change. I also removed the muffler to check the exhaust port for carbon buildup, none. Spark plug tip looks normal. I was leaning towards an air leak somewhere. Once RPM’s dropped I sprayed starter fluid into the intake and it still didn’t accelerate. It has me buffaloed. Any thoughts? I know I can buy a new one but the new ones like this are 2.5 lbs heavier and I’m like you, I want to find the problem. Sure would appreciate some help!
