Upgrades

I was wondering if there are any carburetor upgrade recommendations for my 2 stroke 80cc (66) A50 engine. I want to get one that will give me more power so I can upgrade to a 36 tooth sprocket and high compression cylinder head
 
I think, you gotta let the engine break in for a couple of tanks before starting with the tweaking of it. As long as nothing is horrifically wrong with the motor (like a leaky head gasket or bad assembly woes), it'll run better and better as you ride it. I had the 66cc $100 no-name kit, and once I got the head issue sorted out, I was able to pull the 36T no problem. (I ended up running the 36t so that it was vibration-free at about 25 mph).
I'm not going to take credit for the analogy, but these little 2-strokes are like adopting a baby or a puppy- get to KNOW them, and find out what works first before going in and changing things.
 
so I have had it for about 2 years and put about 100 miles on it, it's probably pretty close to the same engine as yours cause I got mine for $109, and its no name and it runs fine other than the spark knock, and smoke but other than that it's actually pretty powerful but I'm looking for a carb that will increase the performance and idle because I have seen some online saying they make the engine run worse. I'm only asking because I don't want to buy something that doesn't work because I'm on a sorta tight budget.

Oop. Sorry about jumping to conclusions! I had really good improvements with the RT (Del Oro Knockoff) Carb, and the CDHPOWER exhaust pipe. It actually idled decently, was still quiet, but had better low-end pull with the combo. The pipe is about $31 shipped and I think you can get the carbs on Ebay for around $23.

Okay- update. I just checked- and of course due to the stupid Plandemic, now the muffler is out of stock. It WAS a CDHPOWER "Colorful Muffler" on Ebay. Really woke the motor up, and it wasn't hardly any louder than the stock pipe. The combo pretty much fattened up the bottom end of the power curve- didn't do anything for the top-end, but I was okay with that because the vibration was annoying anyway.

The carb is a "High Performance Racing Carb" for around $23.

Hope that was helpful.
