I suspect it lean.

Yes, I agree but why? I pulled the diaphragm off. It was OK but the pin just tests in there. Nothing keeps it from moving around.

I have 2 other carbs. Their pins didn't move around like this.

Big question. How do I find a replacement? Do I remove and measure it. The other diaphragms wouldn't fit. Slightly off for diameter.

raise the needle

[seanstr]

This Diaphragm needle combination has no adjustments to do this, it is not normal.

Some people make adjustments any way...like a tiny washer under the needle. Or several.

This allows more fuel?

[jct842]

If you want to raise the needle up you stick a small washer under it,...under the head. When it is installed with the washer it does not go down as far as it used too.

The washer/washers (because I had a e few one point), didn't help.

I rechecked for vacuum leaks and air leaks from the air filter box to the intake. No leaks. I ordered a 115 jet. I am hoping that is bigger than mine.

I will also take the carburetor further apart and spray choke cleaner down other areas I have not cleaned yet. Use a pipe cleaner or something to safely remove any deposits.

After that It's replace carburetor. I would think.

stock air filter? stock muffler?

[cyborg]

It's lean,,, upjet

[seanstr]

Sorry, yes, all stock.

I am getting the 115 jet, I believe I should have a 109 currently, but What do I know?

[jct842]

Really best to look first before you order unless you get a jet kit. Some people change jets for winter riding too.

Scooters are a poor choice if you want to ride in snow, The small fat wheels slide all over the place in snow. A better choice would be a 50cc moped with the tall skinny wheels with a knobby type tread.

I have seen them come stock 102.105, 108 115 if your running a pod and opened muffler. (this is where I look for Alley)
