How to find piston stop size for Troy Bilt TB575 EC weed trimmer....
This trimmer uses a Champion spark plug RDZ4H. Amazon sells various sizes of piston stops, I'm thinking this might require a 14mm? (see link).

Are you just trying to hold the piston so the engine doesn't rotate so you can pull off the flywheel nut? If so, pull the spark plug and stuff the combustion chamber with clothesline or string.
Impact wrench works wonders, too.

The impact wrench usually doesn't need the crankshaft to be held, or at least not hard at all - a gloved hand holding the flywheel will be enough. If needed, you can pull the magneto off, wrap a rag or oil filter wrench or something around it to get some grip, and then try. Or stuff the cylinder with clothesline. But usually an impact wrench and gloved hand on the flywheel will be plenty.
I love my cordless impact driver. It's a beast.

WTF is this? Oh I see it's going the way like everything else now. Like smoking where there is no smoking allowed, drinking beer in car on the street. letting your dog off the leash in public spaces when it isn't allowed, pooping on peoples front lawn..

You equate events that cause actual harm to other people, with a simple forum post which would have been precisely zero trouble to you at all had you not made the choice and taken an action to click on it. Then you made the choice again to further inconvenience yourself with a post complaining about it.
Interesting. For your sake, I hope you don't live the rest of your life this way.

Typical Newbie Error
The main thing is, you're a newbie and trying to set policy, not your job .
I'm interested in this thread because I'm a Mechanic and always trying to learn new things . ? Is this tool to hold the piston whilst the flywheel nut is torqued or is it to use in lieu of a dial indicator for ignition timing ? .

It is the tool to hold the pisto while the clutch is tightened. I should have the 10 mm piston stop tool tomorrow; will post photos for clarification. |

Thank you very much H.M. .
As an older Mechanic I prefer to use the torque wrench on flywheel & clutch basket nuts but I have an electric (plug in) impact gun tool I mostly use for loosening things . In my long career I've seen quite a few engines ruined by these nuts coming loose .

Both piston stops I ordered are incorrect; there exists a definite possiblity they may put a hole in the piston of a small engine! DO NOT USE!!!
I'm ordering the correct type tomorrow, please watch this video as it may save your lawn mower, chain saw or weed eater from destruction!! https://www.bing.com/videos/search?q=how+to+use+a+home+made+piston+stop+tool&docid=607999111923695649&mid=516845B28DB8AFB2129A516845B28DB8AFB2129A&view=detail&FORM=VIREHT |

Seriously, clothesline or string in the combustion chamber. Cushions the whole surface of the piston, spreading the load out. Easy easy easy easy easy. And cheap. Also universal size, a ball of string fits all engines. You can even use the string for other things afterwards.
