Stonnerdog,

swarn and distroy

Re: question about carb jets

Take apart your carburator and take out your jet screw (see below for instructions). There should be a number stamped on the screw side (where you'd use a flathead to take it out). That's the number of your jet. Most people seem to prefer 52, though I'm using a 55.

I'm not sure what they cost, since I've never had to order one. Check online or call Handy Bikes (best bet). They shouldn't be more than a few bucks. Moped Junkywar has them online for $6.95 (see <A HREF="http://www.themopedjunkyard.com/dellorto.html"http://www.themopedjunkyard.com/dellorto.html</A>;)

To take apart your carburator (these are instructions for a Dellorto, but should be universal, I think), first be sure that the pet cock is off, and unhook the fuel hose from the carburator. Then take out you should be able to take off the carburator rather easily of the manifold. It's OK to leave the throttle cable attached. Next, unscrew the metal bowl off of the carburator (there's two screws there). Now your. Now you should be able to see a white plastic float and the jet screw. Just unscew it out and take a look at it.

I hope this helps.

Before you change the jet, check for a bad float or needle valve causing the bowl to overfill and make sure your air intake is unrestricted by a dirty filter or anything else.

This is a little togh to call on little information.

I asked the questions because main jets do not usually get bigger unless someone pokes something hard through them.

Did this ped ever run OK?

How long have you been running it?

Any other history?

Re: ron

yea it ran and still does some time but has all ways ran too rich or just floods out.

Re: ron

OK.

How about some specifics here.

What kind of ped?

How long have you owned it?

How many miles on the clock?

What kind of gas/oil mix do you use?

What spark plug and do you know if it is the correct one?

Anything else you can think of that may help.
