Remove The Oil Injection System

Pull the spark plug out and attach the plug wire. Hold the metal part of the plug against the frame or the engine and see if there's a spark as the engine is cranked over.

just went and checked and yes i does have spark. try starting it again and just drowns the plug and its soaked again.....ok i figured it out again the darn float was stuck open. this means im after a new carb as soon i can im tired of messing with this one. hope you guys dont mind i keep all my question in this thread. but i have another question. i changed the gear oil with valvoline 80w/90, but my pgo book say 140. will i be ok with what i used?

You may be able to set the float height rather than replacing the carb (usually a metal tang that you can bend to achieve different float heights) or it could be some debris around the float needle or seat. Have a closer look before buying a new carb.

80W90 should be O.K..

Yeah the "Tab" in this pic can be bent upward a little bit to lower the level of the fuel in the bowl. It cures most flooding issues usually. Just a little bend!

[pgopmx74820]

on the fuel valve there there is a little thing on top that pushes down is that supposed to make the rubber end part come out farther?

[Fox]

NO. The rubber tip is stationary. I think that spring is sort of a shock absorber for the float so the tab doesn't bend. I guess. The engine takes a pounding when you hit bumps. the carb moves with it so it's constantly getting jarred.

im guessing it not seating right then, once i get it started i can run all
day but leave it over night itll start then drown the spark plug im guessing till i get all the fluid out of the motor

Sounds like a bad fuel petcock to me. There's a diaphragm valve between the fuel tank and the engine that is only supposed to open when the engine is running. If you remove the fuel line from the carb, the fuel should NOT flow out of the line. If it does then your valve is faulty and that will cause flooding. The valve is opened by a vacuum line coming off the carb/intake. If fuel flows from the vacuum line then the valve is faulty. the only time fuel should flow out is if you suck on the vacuum line like a straw or start the engine.

It looks like this:

just ordered one from scrappydogscooters hope in a few days that fixes my problem

[Fox]

You can use a pair of hemostats (surgical clamp) or Vice-Grip pliers to pinch the fuel line when you park it at night til you get a new valve.

thanks for the tip, it said about 3 days or so for it to get here, so cross my fingers. if these fixes my problem ill just about be ready to get it tag and insured and get it on the road, so i can go get my m on my license

[Fox]

You can go to a lawn mower shop and pick up one of these tomorrow. That would solve the issue.

well tired something last night i put the fuel line into a cup to see if it would drain all night. well ii didnt do it. so now im guessing only thing that could be wrong is the inlet valve is not seating right

[pgopmx74820]

i put it all back together dry and it start for a few second then died, i pulled the plug and of course it was soaked already. i had the screw only turned 1/2 turn to limit the flow and still flooded it. im looking at the 150 cc on scooterdepot.us think the scooter there be ok to get?

[Fox]

scooterdepot is located in Chino, Ca. about 45 minutes drive from me. One time I worked on a scooter for a girl who bought it there and was still under warranty. I called on the phone and talked to the head guy and explained who I was and gave him the girls name and I had the parts I needed arrive at my home the next day. Get the warranty!
