OK, I bought this 192tc new about 10 years ago, as I tend to one hand a saw for trimming work and when I am up in my poor mans bucket (a well secured shuttle cage on my reversed pallet forks on my loader tractor) I used to climb a little, but I am just too heavy anymore and approaching 60.
I run exclusive ethanol free gas and stihl synthetic oil. 50:1 Gas also gets a dose of Stabil before use. I just get 5 gal of ethanol free every month or two, treat it, and use that in ALL my small engines.
So many people gripe that the 192 is gutless etc. But I love it. For what it does, which is small limbs in awkward places. And I can take a long small limb on the ground and chop it into 16" kindling, standing with the left arm holding the limb and the right running the saw.
Anyhow, please no negativity to the 192. Sharp and used right, its a beast.
But....
Lately, it starts as always, revs fine, idles fine. Then bogs nasty bad when under a load. And eventually even dies. So couple of ideas. Some videos suggest that the vacuum relief valve from the gas tank could be plugged. Does the 192tc have that? Runs the same from the get go, so I am doubtful the vacuum building up is the issue. But worth it to check I suppose.
Another thread suggests the carb needs rebuilt and a video shows a hardened diaphragm causing issues. I can tear it apart and see. I am meticulous about gas, but 10 years in 10 years......
Finally another thread suggests the intake boot can fail. That could be the culprit too. Last year I ran the saw over (never sit your saw on your tractor tire), but just dealt it a glancing blow and a new $30 handle housing fixed things. BUT, I had to pull that intake boot out to install the new parts.
Anyhow, looking for wisdom. I really don't think the saw is shot, meaning scored piston. Has the same old compression as always.
Thanks in advance.....
