Question about Troy Bilt Tb320bv Spring Assist Blower/Vac

1 Answer

I had bought a troy-bilt 2-cycle mulching blower vacuum model tb320bv last november. i used it twice before winter and took it out in the spring and used it twice before experiencing something odd. the second time i used it, it ran fine for about 20 minutes and then just shut down. i thought i was out of fuel, but was not. i tried to restart it but to no avail. changed plug, thought it might be fouled. checked for spark, spark ok. acted like a plugged fuel line. i called store and was told to bring in with reciept for warranty. i get call from store saying it has regular gas in tank. i say no way is that possible. theycall me a second time and say there is a oil gas mixture in tank and that the exhaust side of the head is scorched which reflects gas usage in blower. have you heard of similar problem with this model or others. should i pursue this or let it go? will troy-bilt be of any assistance to me?

This problem can be due to burning of old fuel mixture which may have resulted in scorched head. I would suggest you to take it to troy bilt as this requires changing of parts and checking several other things while changing the part.

If the problem is not what they said then the blower/vac will start by this- turn the choke off, hold the throttle wide open and crank. If the blow/vac starts then the issue is due to carburater and if it doesn't start then its the scorched head.

Please do accept this solution and revert for further assistance.

90 psi or higher is usually what I like to see. If it gets lower then that it can often be hard to start.

Replacing the pull cord on my Troy Bilt blower/vac (TB320BV), & I can't get the nut off the crankshaft extension, the last thing keeping me from the starter housing. I've tried clasping the flywheel...

Same problem here.After snapping a couple fins off the flywheel trying to lock it with a screwdriver, I had an idea that worked quite well.I used an oil filter wrench (designed like pliers) Item #36778 at harbor freight.The thin design held the flywheel well (very tight fit,had to force past the plastic housing) while I used a socket and power handle.Worked for me and used it when torquing the crankshaft extension nut tight again.

What type and grade of oil is required. I have lost my manual and do not remember what oil is required. Troy model TB4SC gas blower.

Any 2 cycle oil will work. Then mix 1 gallon of gas to 1 container of 2 cycle engine, shake well and pour into your blower.
