Hey gang... I got out the vom like ron suggested and found a few problems. a new wire and viola I now have SPARK.....

however.. Just as I suspected my home made fuel petcock is leaking very bad.

I just took a car brass fitting nipple and screwed it into the tank then ran a rubber hose from it to the carb. I wasn't sure if it was getting gas so I like an idiot pulled the hose off the top of the carb and was instantly soaked with gas and about a 1/3 of a tank worth of gas rushed out before I could push it back down onto the carb.

does the petcock regulate the amount of gas going to the carb? or does some how the carb regulate itself or how does this work?

I pedeled till my legs were wobbly when I stopped.

any ideas where I could get the proper fuel petcock or regulator or something? would this be a problem or is the more gas the better?

thanks .. duck.

*****very very excited he finaly got spark!!!****

Normally, the petcock has nothing to do with fuel regulation. Some have a priming position, but I doubt the peugot does. The fuel is regulated by the float and needle in the fuel bowl. When the fuel bowl empties, the float drops down, which drops the attached needle and pulls that needle away from it's seating position, letting fuel into the bowl. Once the bowl fills up, the float rises and pushes the needle back into its seating position, sealing off the fuel flow until the amount of fuel in the bowl is lowered again.

It might be a misadjusted float level or a dirty carb. Did you clean your carb out thouroughly? I don't know my peugot's very well, so I couldn't tell you how to adjust the float level (if that's the culprit), but the carb should be cleaned, priority #1.

But now that you have spark, it should be relatively easy to get running!

And dont forget the in-line fuel filter. You will be amazed at how much crud they collect. But its good to hear you got a spark, like Brandon said, you should be close now! Good luck!

The little needle valve that is in the carb can get very crudded up. It only has a little area around it for the gas to go through. If you take the bottom bowl of the carb out, look at the float needle attached to the bowl. It is probably munked up with years of gas going through it. Also, the jet (should be sorta near the center of the carb when looking at it from the bottom) could be clogged completely shut. Use a very thin and stiff wire (like out of a bristle brush) and push it through the hole. There may also be an idle jet beside it. Double check the choke while you have the carb off. Make sure it's working correctly. No chokey ,no gassy, no cranky.

You might spray a little gas (mixed) into the carb just to see it turn over under power (its always grattifying to heer the motor pop over after working on it for a while).

BE VERY careful about the parts in the carb. They are easy to loose. I was cleaning one on a little suzuki and lost the little needle valve in the grass. (walking from the shop to the moped, damn thing jumped out of my hand on its own I think)

The new one was 28.00 from the dealer and took 8 days to come in. (they might have had one in stock and just wanted me to suffer. The suzuki fa50 has the same carb that the current 50cc mini dirt bikes use).

Good luck!

Duck,

Brandon about covered it. This fuel level regulating mechanism is known by highly trained professionals as the "toilet tank" mechanism. If you want to know how it works, take the top off the tank behind the toilet, flush and observe. : )

Seriously, you do need a way to turn off the gas because needle valves do leak and your carb will flood while the ped is parked. You can carry a pair of vise grips and pinch the fuel line (not recommended), or pick up an in-line shut off at the lawn mower or hardware store (recommended).

You do not need this to start the ped. You do need to follow Brandon's advice and clean the carb.

Pedal away.

Ron

After you've pedaled the thing as much as you say, pull the spark plug and see if it is wet with fuel. If the plug is dry, which I suspect it is, then you're not getting gas to the engine.

That's a quick and easy check. The other advice you got is sound. I'll bet the carb is not passing gas (no pun intended).duck wrote:
