[1986Beauty]

So I have had this 1986 honda trx125 for a good 2-3 years and the entire time I've had this issue with it skipping it's revs when idling and in gears. I don't quite know what is wrong and was wondering if someone could tell me how to fix it. And just so you know, I have changed the battery, air filter, carburetor, fuel filters, spark plug, and the wire that plugs into the spark plug. So yeah I have no idea and was wondering if someone could help me.

What does the spark plug look like ? Dark ? White ? If it's white, try taping off part of the airbox inlet. If it runs better, go up on your jetting
