Alright Bobby, let's get this wrapped up.
I measured your cylinder, and you're right - it's a 61mm piston and cylinder. There isn't any explanation I can think of other than being inadvertently sent a 61mm kit from the supplier. To make sure this can never happen again, I'm going to machine a go/no-go gauge from a 62mm piston that will be used on every engine being built going forward.
If anyone else who bought a 175cc from us around Jun 23, 2017 is worried that you may also have a 61mm, let me know and I'll start a new thread - to check, confirm, and recall if necessary.
As promised, I'm putting my entire box 61mm pistons up on eBay for $10 for the lot. And I'm issuing you a credit of 100 doll......
Wait, there is a problem...

I've highlighted in green where you are correct, and stating factual information. I highlighted in red where you are misrepresenting things again.
Personal attacks and Badgering
People tend present things in ways that support their feelings more than facts, and you've done that repeatedly and unapologetically in our interactions. I feel obligated (and fine) calling you out on false statements. My responses are direct and to the point, but you seem to be implying that I'm being aggressive/abusive. If you believe this, give specific examples. Are you actually feeling attacked? If not you, then who specifically?
A false implication is a lie, Bobby. You know what you're doing.
I want was many of my visitors as possible to read and consider my responses in complaints.
Our reviews and my responses are openly viewable on the Buggy Depot homepage for everyone to see who may be considering purchasing from us on a daily basis.
My reviews section isn't a hidden club - it's extremely public, fully transparent, promoted in a prominent location on the Buggy Depot home page, and wide open for all of our potential customers to see. I've willingly and openly handled customer complaints in public here uncensored for over the last 13 years - our entire history is here.
My problem is when a complaint or review is less than honest, or is based on unreasonable expectations. In a minority of cases, certain individuals go way too far and significantly cross the line. I'm talking about guys who use drama and exaggerate their complaint in an effort to extort more from the seller than they actually deserve in the situation.
For me, dealing with complaints isn't just about responding and hoping they go away. If we make a mistake, my history in reviews shows that I take responsibility and correct the problem.
However, if a person isn't speaking truthfully or makes unreasonable demands, it becomes about sending a message to everyone reading that certain corrupt behaviors in complaints will not work here. I want my 1,800 daily visitors to see me as an Owner actively calling out alternate facts, exaggerations, and in some cases outright lies. I'm fine with being controversial and a bit unconventional.
Agree with my approach or not, I'm completely transparent and up-front about it.
If a reviewer feels embarrassed after evidence and screenshots show that elements of their complaint
aren't truthful, then my message (both content and tone) is having its intended effect.
I want this behavior to be discouraged and socially unacceptable. You can be upset in your review, just don't be fake, exaggerate, or make up things that didn't happen.
The BBB is good, but doesn't have enough reach.
Our homepage gets 1800 views per day, which is why I put these reviews there, front and center.
I'm going to continue calling out fake review behavior directly and consistently, and will continue to figure out more ways to get this message in front of more of our potential customers up front. If I were acting aggressive or abusive in reviews, it's open for the whole world to see and judge for themselves.
Having these reviews on our homepage makes it impossible for me to hide anything.
Fake Reviews and Cowards
I agree that "What to do about 1-star cowards. My thoughts." is a good title to raise eyebrows. I worded it that way specifically to get more people to click on the title, read my post, and consider what I'm saying.
Intentionally taking the title out of context and turning into a soundbite is fake news. It's a lie. You're presenting my words in a false context and hoping people are too busy to read the link. Anyone who hasn't already, should
read the full post and not let fake news win.
Now specific to you: I haven't put your complaint into the fake reviews category, because it doesn't belong there. You didn't run away after I showed several of your initial points to be untrue, you worked with me towards a resolution. So no, I don't consider you a coward. But I still have to call you out. You play very loosely with the truth. After this interaction, I'm considering add a 5th condition to the fake reviews section related to repeated intentional and willful misrepresentation. Liars.
A half true statement isn't the same thing as a true statement, Bobby.
Since we keep running into this problem in which you repeatedly misrepresent the situation with half-truths, I'm going to misrepresent my own offer to half of its original amount. I've issued you $50. To everyone reading this: I won't accommodate people who aren't playing straight. I'm going to treat individuals with the same level of respect and patience they're showing us. Don't get upset if the reflection in the mirror is something you don't like.
I'm going to go ahead and write a response to the BBB calling attention to my point of view here. Again, transparency is the key. People can judge my position for themselves and order accordingly.
And Cheetha raises several good points.
Whether people agree with me or not, this forum is open for anyone to comment. Anyone who agrees with Bobby is 100% welcome to speak their mind, and can articulate a case that might change my mind about things. That's how freedom works.
'Murica.
