    Stumped on Stihl BR450 Blower Stopping

    Thanks for the last couple of replies. I have replaced the coil and plug. There was nothing wrong with the original coil. I am convinced the issue is not ignition related. Earlier, I mis-spoke about the fuel/oil ratio. I have only ran 50:1 ratio. I used to have a Lawn Boy mower that was 32:1...

    Stumped on Stihl BR450 Blower Stopping

    I stand corrected, the engine is not made in China. Some previous power equipment history and frustration mixed in my comment there earlier. I talked to my local Stihl service guy, and despite previous troubleshooting steps, he said it still sounds like a carburator issue. He has ordered a Stihl...

    Stumped on Stihl BR450 Blower Stopping

    Fool me once, shame on you, fool me twice, shame on me. What other brands are recommended for a pro quality backpack blower? With everything being made in China now, does it even matter?

    Stumped on Stihl BR450 Blower Stopping

    I used the blower on Saturday each week since my last post, and it ran as normal. Each session wasn’t very long, less than 30 minutes. Today, I’m getting more into leaf season, and I ran it for longer. I was almost at running out a tank full of fuel, and power started decreasing. I needed to go...

    Stumped on Stihl BR450 Blower Stopping

    There are week lapses in my responses because Saturday is my day to do this type of thing. This weekend, I replaced the diaphragm and the other thin film piece (which has the flapper for pulsing/pumping the fuel) in the original Stihl carberator. I filled the tank with the Shell fuel, and ran...

    Stumped on Stihl BR450 Blower Stopping

    Sorry for the lapse in replying. I went to the Shell station and mixed a gallon of 93 octane. Their gas is up to 10% ethanol like Citgo, so I'm not expecting it to make much difference. Not really sure where there is pure gasoline in my town of 60k. Saturday, I took the blower completely apart...

    There is a convenience store near my subdivision that has Citgo gas, which is what I've used for over 20 years. I will go to a Shell station and get some fresh and report back.

    Stumped on Stihl BR450 Blower Stopping

    I have a BR450 that I purchased new in 2018, which has performed flawlessly until recently. I am a homeowner who uses it once a week during the summer months, after mowing, and multiple times during the Fall leaf season. I do not believe it is "worn out", like piston rings, crankcase seal, etc...
