What backpack blower should I get

You threw me for a serious loop when talking about valve adjustments while running 2 cycle fuel. I had to Google your model and learned something new today. You say the plug was black... Any chance the rich condition caused the muffler to get partially blocked? I once picked up a chainsaw that idled and ran perfectly at partial throttle, then fell flat once I goosed it.

 

Well I think you learned me something too. I didn't put much thought into it until you commented. I've ran a br800 at my previous job and had no idea it had valves.

 

I've had the PB 770T for 4-5 years now. Runs like every echo I've owned. Excellent .

 

I can't see any sort of caps or blockers in the schematics. I'm guessing there is a proprietary driver that fits them for adjustment?

 

BTW, I have run the Makita a bit but not extensively. My first real blower so I cannot compare it to anything but itself. Seems eager to run and blows what seems to be good volume of air. Bit portly but they all are when you're not used to lugging a ruck around on your back. Acceptable sound level to run extended without ear protection.

 

I mount mine on the back of my garden tractor and use it from my seat. All the neck surgeries prevent me from wearing mine. Id rather wear it but my setup works good enough.

 

I regret going with Stihl on this blower. I'd trade it for an Echo and eat a couple hundred dollars if I could.

BTW I reached out to Stihl to check if it's still under warranty (it is, but it would be under the double warranty fuel program deal). Of course they didn't bother to respond.

Yeah the 4mix concept is fascinating.

It wasn't running rich enough to clog anything. Spark screen was completely clear.

Yay more proprietary crap. Happen to know if there is a aftermarket carb available for this unit? I think my plan of action right now is to try to find a new carb and see if that fixes my problems and if not I'll drive the two hours back to the dealer I bought it from and roll my dice with the warranty. Who knows, maybe they'll buy it back at a loss. Just really fuming at Stihl in general right now. I have had nothing but trouble with my Stihl chainsaw as well. I assumed a backpack blower, being essentially maintenance-free compared to a saw wouldn't be giving me troubles after barely being broken-in.
