Question about Troy Bilt Tb320bv Spring Assist Blower/Vac
This unit is 5 years old and has always performed well. suddenly it has become hard to start and stalls if you try to accelerate. it seems like it's not getting fuel...but there seems to be plenty of fuel flow to the carb.
All of these "starting/running" issues are similar and related directly to one cause. It was suggested several times that the muffler may be plugged, but mine was found clean during a complete teardown. Cab cannot be blamed either, since the fuel filter wouldn't be able to pass anything large enough to foul an orfice.
Very common issue with hot running two cycle engines...ring fouling and loss of compression. The brand or type of oil must be scrutinized, and the mixture kept exact. I would never use anything but Echo or manufacturers recommended oil in these units ever again.
