I purchased the unit from Lowes in 2010, thinking like everyone else that TB had a good rep. I used the blower 1 time for maybe an hour (prob less) and started having a loss of power then it just quit all together. I was about finished with the job anyway, so I put the unit up till I had more time to deal with it. A week or so goes by and I pull it out and it cranks right up and runs. So, I put it away not sure what had happened. Got it out this fall, of course by now my warranty is out, (my fault) and cranked it and it ran fine for about 5 minutes then began the loss of power routine again. So I do some research and see that the ignition coil is a big problem with these, so I do some troubleshooting on the unit to find that is not my problem.
Finally, after tearing it all apart, I find that the problem is the intake valve is stuck open. I am able to free it and again it cranks and runs for 5 minutes or so, then I can actually hear the valve starting to seize again. After a few minutes of cool down, I can hear the valve actually pop and it reseat, allowing the unit to crank again for 2 min or so, it depends on how much throttle you give the thing, but seizes again. My guess is that the valve is bent slightly or that not enough oil is reaching the top of the motor. Since it only happens with the intake valve I am going with it is bent either from heat or just cheap parts. Moral of the story is I am like everyone else, throw it away and start again with a higher quality unit. Parts are available but by the time I buy the part, repair it and hope it runs better the second time, my ignition coil will probably die, which seems to be the most common problem with them.
