Oops ...

Ok so my carb doesn't hold tight to the intake, so I have to epoxy it. Well it came

loose, and I re-did it, but when I did, the carb now sit's not exactly level. Looking

at it from the air intake it is tilted about 5-10 degrees clockwise. Well the ped

wont start. How important is the carb being level to starting ???

Can you start the engine if you tilt the moped enough to level the carb?

I guess you could put it on the stand on ground that slopes at 5-10 degrees and have somebody prop you up while you pedal...

No can do. Delaware is FLAT.

But seriously the carb is at a 45 degree angle to the bike, and twisted on the

axis of the intake. So tilting the bike would require leaning it to one side and

lifting the front wheel a few inches. A cool wheelie while riding, but hardly how

I want to start the bike :)

Re: Oops ...

why did you use epoxy?! oy!

if you can undo it ... try just using a shim. i assume that by intake you mean the manifold? just take a piece of thin sheet metal and wind it around the manifold to make a shim ... then tighten on your carburetor. worked for me.

Does it fire if you soon a little gas in the intake and are you sure you do not have an air leak wher you epoxied it?

As you look at the carb, if the float bowl is now lower than the main jet (base of the carb slide), you will run lean and visa versa. If the bowl is still at the same height as the jet, you do not have a problem at all.

I thought you said the carb was at a 5-10 degree angle!

I suggested starting it on a slant as a diagnostic maneuver (if it started when leaning, you know that the problem is definitely the angled carburetor and you would have to fix it).

If your carburetor is tilting at a 45 degree angle, you've DEFINITELY got to get it off and put it back on level. Even if it did work at that angle, your engine would probably conk out everytime you made a turn in the direction the carb is leaning...

No, the carb isn't tilting at a 45 degree angle, but faces that direction. I "attempted"

to explain, but obviously didnt do very well. If my bike is riding facing 12:00 then

the air intake faces about 4:00. Now if you were looking at the air intake, the right

hand side of the carb is lower than the left at an angle of about 10 degrees.

Re: Oops ...

My carburator runs at that angle constantly, and has presented no problem.

I think a lot of the fuel/air flow is due to vacuum, not gravity, so I wouldn't worry

about 10 degrees.

Re: Oops ...

some moped carbs actually are facing in different directions. some puch's face backwards. some italians face front, others to the side (90 degree). so don't worry about where your airbox points, so long as the carb is on correctly and level to the ground, i guess.

Re: Oops ...

I seriously doubt that 5 to 10 degrees is gonna cause any probs. There's enuff shaking and agle variations going on during starting and riding to ensure that enuff gas is getting into the bowl. Most engines can run up to about 30 to 45 degrees of tilt before cutting out.

One simple test you can do is to slightly loosen the float bowl on the carb to determine if the float valve is operating correctly. If it leaks and continues to leak, the valve aint shuttin off which is causing the engine to flood.

You may have to take the bowl all the way off to see if the carb is gettin enuff fuel. Simple test for that too. Take off the bowl, hold it underneath the carb and let it fill up (that is, if the gas IS getting to the carb) then slowly lift the bowl up to the carb, as if you were gonna re-attach it, to see if the float will shut off. If it shuts off, then all's well. If you don't have gas running into the carb at all, then that's another story.....good luck.

Re: Oops ...

Hi! I just wondered if you're sure you didn't bind the choke up when you removed the carburetor or maybe got some epoxy into a critical area? Just a thought.Hope you get it fixed!
