That way you can be 100% sure it’s fine if you’re concerned.
We really shouldn’t discourage people from trying to fix thins because of fear.
If you need to try a repair again checkout YouTube, the small engine guys on there are really, really good. They've got tricks even I'd never heard of before.
I refuse to believe someone who is attempting to repair an internal combustion engine does not know that gasoline is flammable and the working area should be ventilated (or outside), particularly if they’re working on the fuel system.
Sure. But people do occasionally ignite gasoline by accident. It's uncommon, but the consequences can be very severe.

Funny thing, the replacement batteries are much larger in capacity now, but the price of a single replacement battery is the same cost of a new powered tool. So, I wound up getting a new tool that I didn't have with a new battery. I have a few LiPo batteries for my cinema camera gear that have died as well. I'm going to try to find someone that can just replace the batteries packs inside the custom housing.
Very few exceptions to this rule for me, and I generally avoid anything with a Micro-USB charger like the plague if I can, as I can't help but see it becoming e-Waste in 3-5 years.
Solution: find a very thin pin and ream out the buildup in the carburetor, and all the steps leading up to being able to do that. The sense of personal (horse)power I felt after reviving that engine was palpable.
It's funny cause now, just based on that experience, I'm not saying I'm an expert, but I am saying if I encounter any small engine that won't start I will eagerly start trying to figure it out. It looks fun now. The brain is weird.
