Brainstorm 2-stroke bogging with me....

That o ring at the end of the manifold tube was all mine needed. Norm does his with sealant instead of the oring. The oring is set at the very back of the manifold tube and seems to stop everything for me.

I hear you, but even with the o-ring I could "see" air passages.....besides, I can be anal if I want.........

Anyway I got me a 1.5 oz tube of this: Permatex #2 and sealed that dude up. My little Firefox weather dohickey show sun tomorrow!!!!

Yea you will be able to see the slots cut in the carb when you use the silicone but it will seal better than an o-ring its got to have pressure against it to work ( the o-ring) and if it comes lose your engine will eat it might not hurt but if it snags on a port and breaks a ring your going to be in deep poo. The silicone works for me have not had a single leak and its very easy to use and clean off but I'm not going to try and talk you all out of your favorite way if you want to use an o-ring just letting you know what can happen if they get lose and wreak your bicycle motor then you will not be able to ride your motorized bicycle until its repaired. something to think about.

Or drive you all crazy wondering will it come lose or not.

got you wondering yet?! To check for a leak free seal spay the area with carb cleaner or starting fluid you could use a spray bottle of water if you have to all will change its idle if there is a leak most likely it will die when sprayed and its leaking. do not spray the intake as it will die making you think you have a leak when you don't

I think the best way to check is to slap a thick coat of axle grease on the joint and if it runs okay clean it off and fix it lol.

I sealed it all up and it runs better. But is still bogs.....dang it!!

I can feel it has more power, that's for sure. I can rev it pretty good when there is no load. But still, even when warmed up full throttle under load, it goes into bog mode.

What the heck should I try next?

It is possible you got all there is out of it. Mine going up hill does that, it just gives all it's got and it ain't quite enough so it just moves at its own pace. course you could move your needle again. Try to adjust it that way. They also say you need to run them a while to break them in and they will perform better when they are broken in better.

Try one notch lower on the needle clip and see what changes.

OK I just came in........arrgg.....this is getting fun.

All the outside fiddling hasn't helped. It started to backfire through the carb every so often (clue Norman?) so I decided to attack the beast.

First of all I took the carb off and took it apart. Pretty simple really (yes Norman the O-ring was still there). The main jet appeared clear. I didn't mess with this:

Should I try messing with the float???

Put the carb back together. Then I took the manifold off. Found a big oops there....I didn't realize how lousy the gasket matched the engine. A big portion of the ill fitting gasket was being pulled into the engine. So I carefully cut the gasket to fit.

I put a new O-ring in and buttoned it all up with a little sealant.

It fired right up, sounding really good, nice midrange power....but go for full throttle and BOOOOOOOOOOOOOOOGGGGGGGGGGGGGGGGGGGGGGG......

Dern.

So far I didn't mess with the needle.

Something is fundamentally wrong.

I just did and it made it worse. That should make it richer. Indeed it did. So next I will try the top notch, I guess.

Check your Gas Cap. If there is no hole drilled, then you need to drill one. A gas cap that seals too good and has no vent hole will cause the very problem you speak of. Thanks..Enjoy the ride... Titan is coming.....
