watch all these and study them. I learned tuning from that lutz tuning video. Reason I put the other 2 carb setup videos is cause you need the carb set properly before you can tune

Idle gap is too wide. Start at .5mm.

May need to richen the needles too. It’ll bring the idle down.

stick with it. I know it can be discouraging in the beginning. Definitely read up and watch YouTube vids. They will help tremendously!

Yea learning nitro is patience. Also make sure engine has good compression no compression can lead to having a not stable idle.
When you push flywheel on bottom is there resistance. If it's easy to fully push it around and don't feel any resistance the engine doesn't have compression. Another test is when engine is out of car hold it by the flywheel if the engine can't support its weight at all and rolls over right away then compression is low.
Watch those videos I sent. I know there long but setup with a nitro car takes time setting up then takes time to find the tune and really takes time to learn it. I would tune and be ok at it. But I really learned a lot after that lutz tuning video. It helped me understand how to tune but linkage and carb opening are key to.
Maybe make a video of it. It's hard to tell you what to do over the internet also check your clutch shoes and bearings If there in good shape. Broken clutch spring or blown bearing can lead to the clutch being engaged leading to the car driving without gassing it. Linakage not set right can also do that. Set up is key.
If you were close by I'd give it a look for you

I used to always want nitro. I did R/C as a kid and remembered the 2-5 minute battery life, so discouraging when you are young and just want to play. Good luck tuning, hope you get it working! If not, brushless and batteries this days aren't bad either.
