Engine Trouble Bolts keep falling out.

[SerHofi]

So I have a 2 stroke, I got from someone on Facebook Marketplace.

The engine runs well. But after about 10 minutes of riding, the bolts holding the carburetor and the muffler come loose and fall out.

I have tried using locktite, tried different headed bolts so I can apply more pressure when tightening. But no matter how tight they are, they seem to vibrate out anyway.

Anyone have any idea on how I can keep this from happening? I have gone thru about 6 sets of screws/bolts but no luck.

Any help would be great. Thank you.

Blue locktite right????? try putting more locktite on the intake bolts like a good amount don't skimp out , as for the exhaust its probably just melting the locktite. so I'm not sure what to do about that.

There's a reason they call these Happy Times motors.

Your such a TOOL lol

Lock washers and blue lock tight should fix you up.
And do not tighten them too much or they will strip out.

Make sure you are using a high temp blue, aka 243. Normal blue loctite (242) releases around 225 to 250 degrees Fahrenheit, which is about how hot these engines get. 243 holds to 350, so if it let's go, you are having some heat issues.

Thank you guys. I’m going to give the higher temp loctite a try.

Going to try fixing the exhaust to the frame of the bike somehow too. Maybe take the weight off of the studs.

Find some gap filling loctite
