Not really you have a leak somewhere you have to. I have worked on bikes for a long time and I have never seen a bad carb. There just isn't much to them. I have seen damaged slides and torn diaphragms but never a bad carb. Something somewhere is sucking air. You might get lucky with a new carb but i think your problem will still be there unless your carb is grossly malformed or cracked... of course its hard to tell what's going on in the tiny pictures of the carb you posted

Had the bottom of the intake buffed and polished because there was a lot of paint blistered there,used a little permatex red just waiting on the new carb. Yes you may be very right about the vacuum leaks but I can't find any at all. I'm really lost  |

Seriously some nice detailed pics might help us see something your missing. Lots of angles of the usual suspects...

Scootnwinn is right the carbs on the scoots are very simple, and if it is running LEAN and you have the AIR screw turned in all the way your sucking air from some other place OR your JET is clogged and or passage is clogged or jet to small.

Here the story: When I start it up of a morning it will start without giving it any throttle,of course the enricher kicks on sometimes.After it starts to warm up the enricher kicks off an then sometimes it dies so I have to give it some throttle.When the engine warms up a little it's rich,but the hotter the engine gets the leaner the exaust is. So cold engine (rich) Hot engine very lean. A buddie of mine said it's got some kind of junk the EPA put on it,so no matter what jet you use it will still run lean.That's the way it really does run. It makes no sense to me at all. My air box also floods with fresh oil also. Yes I wished some of you guys were my neighbor so I could prove my point.Right now it wont run at all, no fuel coming out of carb. the plug is bone dry. I'm waiting on my new carb. to see if that fixes my problem,unless I have a hole in the piston.  |

Have the cases been split? Also didn't you say the exhaust is leaking?

[replyingto=scootnwinn]scootnwinn[/replyingto]Yes the cases have been split. Yes a little leak on the weld where the connection to the exaust manifold bolts too. Now we may be getting somewhere? |

I think you are sucking massive air and since you have eliminated the usual suspects your left with the cases. Have a good look see if you can see where or get a new gasket and split them again and reseal.

[replyingto=scootnwinn]scootnwinn[/replyingto]When I resealed the intake and intake gaskets I did notice some gasket material missing,I figured that Permatex would seal it off,but I was wrong.I'll sure need help rebuilding that engine. |

I've got a new gasket kit but there isn't any gasket for the center of the engine. Where can I get one? Or can I just use gasket sealer? I got this gasket kit from Scrappys.Also is there a website that I can go to on how to split a Minarelli Jog Type Engine 50cc??
