i lowered the clip still pops i ordered a 38 idle

[millsc]

maybe it pops because of the egr my manifold only has one nipple i disconnected the egr but didnt block it off any way to block the cover without buying a new non egr one

Do you have an EGR or a PAIR system they are 2 different things. The EGR is a VALVE on your exhaust pipe the PAIR has a Valve in front of your VALVE COVER. But anywhos, just use JB WELD and plug up the hole.

OR you can just get a "Y" or a "T" and connect it.
Either way CASES is solved ;D

its a pair valve cover already have a "t" connector since i have a 24mm carb but all spots are filled jb weld the big hole on the valve cover where the hose is?

[millsc]

nevermind i took it all apart made a plate took all the pair crap off seem to do the trick

[Alleyoop]

Yep that is the best way, they even sell the plate for $10 bucks to block off the hole.

You can carve your own grooves in the needle if there are no adjustments. All I used was a pair of wire cutters, sliding them around to make the cut with light pressure.

Must of been leaking, popping on decel always look for leaks cause it creates a lot of suction on decel and any leaks will make them run lean. If a really bad leak they will backfire.

Hello All,

So I am not at all knowledgable about scooters starting off with that.  First time posting even but I am stumped no duh right.  My 50cc Roketa, assuming Chinese manufacturer coughs and pops when I am riding it.  Through my research I am assuming this has to do with the Air/Fuel ratio and the lean/rich running issues.  I am trying to adjust it, but getting nowhere.  The recommendations on this thread are alittle above my level.  So I shall list what I know to be the best description of the problem I can.  

My scooter is 5 years old.  about 4000 miles on it.  I have never touched the Air/Fuel screw before.  When riding it idles and starts ok, sometimes starts harder than others, takes twice and alittle throttle.  Riding the scooter it runs great until about 25-30 miles an hour, then it starts sputtering and makes a popping noise.  Its sporadic, sometimes never doing it but other times it is so bad I can barely go 20 miles an hour, constantly coughing and lunging.  I have turned down the idle screw to where it sounds the lowest it can go without quitting and tried adjusting the Air/Fuel screw but nomatter how many 1/8 turns I do, the most I have done is a complete turn in either direction, I cannot here a change in the idle speed.  I have tried running it when the screw is in all sorts of positions and the same problem continues.  Any thoughts or something I can do would be greatly appreciated.

Dirt in a jet sporadically? i'd take the fuel bowl and check for dirt
