I can’t be positive about anything, but I wouldn’t think the valves are the problem. I think the engine could still be running lean from the air filter & exhaust upgrades, so would getting a bigger jet or messing around with the fuel/air adjustment help solve the problem? Again i don’t really...

Tried this, and it ran even worse than before, it wanted to cut out almost immediately. I assume the problem has something to do with this, so would upgrading to an even bigger jet (current one is .038) alleviate the issue? Also, I’ve read about the air/fuel mixture screw, could the engine be...

Newb. Had no problems with the engine last summer, recently I picked up a stage 1 kit (with jets) and when I’ve been running it, after about 20 minutes, the engine starts to cut out, and can’t be restarted without waiting a while. I don’t know if this is related, but its currently about 40F...

Newb. Adding a stage 1 onto the mini bike, and went for the side exit header. Unfortunately, I’m a couple mm off - I’m unable to completely bolt on the exhaust without the frame getting in the way. Would there be any downside of using multiple gaskets to space out the header just enough to clear...

I’m not sure if you’ll see this again, but thanks for your help anyway - the problem ended up having to do with the airbox only being secured by one nut, which created a leak. When my brake nut broke, I ended up taking one off the airbox that was the same size, and used it for the brake. I...

Thanks, I’ll look into adjusting the ratio, and post pics if I need help. I also should’ve mentioned this earlier but yes, a while ago, I could get the engine running on choke, and it would cut out when I’d flip it off, but after I tried again today I couldn’t even get it started all - maybe a...

I’ve toyed around with the idle screw, but that doesn’t seem to be the problem. But how would I change the carb mixture ratio? I’ve also looked through some other threads and seen some things regarding the spark plug possibly being deficient - should I look more into that?

No dice. Im a newb so I don’t really know much, but this wouldn’t be some type of spark plug or oil issue, right?

It looked alright but I’ll give it a shot later, thanks

Yep, around there

I actually already replaced it, when searching around I thought that was the problem as well, but I suppose not

I’ve had my 212 running good for about 6 weeks, and one day when I went to start it up, it would only run when choked - when I would switch it off, the engine would die out. I replaced the carb and checked for any leakage but nothing seemed to work. One thing I should also mention is that the...

Alright, so I really don’t know jack about small engines but wanted to do a mini bike build. I’ve pretty much got everything else figured out, except I’m having trouble starting up the engine for the first time, and it seems like no matter what I do, it won’t get going. I’ve checked the spark...
