I had a Ryobi 2-cycle trimmer for years and loved it. When the trimmer lost power I decided to buy a Troy-bilt trimmer because of Troy-bilts reputation. Troy-bilt makes wonderful lawn tractors and cultivators. I found the Troy-bilt 4 cycle trimmer at Lowes and got all excited. I could continue using the attachments like the blower from the Ryobi.
I like the fact that it's more quiet than the 2-cycle and doesn't have that nasty exhaust, like the 2-cycle, but that's where the love affair ends.
I was quite surprised with the combination of steps you had to go through to get this thing started. First you have to prime the pump ten times. Second, you have to pull the cord five times with the switch in position 1. Third, flip the switch to the second position and pull 4 times. If it starts running leave in second position for 30 seconds and then move to third position or open throttle. With other trimmers I had to push the bulb three times, put it in choke, after it started put it in full throttle.
When I first bought Troy-bilt trimmer the line was causing the engine to stall. Using the trim line the manufacturer sent with the trimmer, if it went past the cutter an inch or more the engine would go into a spasm and shut off.
If you have the Troy-bilt 4-cycle trimmer do not use the .095 mm square trim line. It is to heavy for the engine. Use only the .095 mm round trim line.
I've used several trimmers in the past and this is the first one that rests on it's gas tank. There is no protection to prevent abrasion to the gas tank.
I would recommend finding a different make/model 4 cycle trimmer.
