Brand New 80cc won't run

[kuch]

Getting fuel and spark.

Messed around with the choke and on/off fuel valve on the carb, got it running for about 10 seconds, then nothing.

Too much fuel? float? I do have another carb, which is different model. Should I try it?

Also been messing around with my kill switch wires. Have two of them, one wired to the white wire from the engine and the black grounded to the frame. Is this right?

Wires: Black to black, Blue to blue. from CDI to Engine.
The wires coming from the throttle connect into either the black or blue left over holes from the engine. Doesn't matter which color wire goes where.
White wire is a left over wire which is normally used for a 6 volt light. Its best to isolate the white wire from the rest via sticky taping it.

when the choke is up it should start the bike, after it has started move the choke in the downwards position and the engine should stay on.

Fix the cdi wiring and see if the engine starts and stays on. Let me know!

Hope this helps.

I have the CDI hooked up right. Blue to Blue, Black to Black.

What I researched online was how to hook up the kill switch wires. I have a yellow and a black wire coming from the kill switch. I was told to hook the yellow to the white wire coming from the engine, and the black wire mount to the frame of the bicycle. Not sure if this is right or not.

What do you mean "the wires coming from the throttle connect into either the black or blue left over holes from the engine"... left over holes?

Thanks for your reply! Hopefully get this baby running soon!

Wires....
From engine (3)
1. Blue... Voltage
2. Black...Ground
3. White...Cut or cap off

From CDI (3)
4. Blue..Connect to 1 on engine
5. Black..Connect to 2 on engine
6. Plug wire.. to the spark plug

From kill switch (2) (don't pay any attention to the colors)
7. One wire to 1 and 4
8. One wire to 2 and 5

This is another..

This topic has been covered NO LESS then 100 times...SEARCH before asking.

Tried that. Blue to blue, black to black, then spliced the kill switch in. capped the white. still nothing.

Take your time, you will figure it out.
If it ran once, it will fire up again.
Check for air leaks, that's a big one.
Loose spark plug etc.etc.
The spark plug connection on the kit is cheep, make sure it's on correctly. The cap to your spark plug should be OFF. Then the spark plug boot will fit on correctly. This is not really spelled out in the instructions.
Good Luck

From the OP it sounds like it got flooded out, originally, then started messing with the CDI wiring.

Is the plug all wet?

Clean it off, and check for spark...
(NOT the best thing, but use some 220g sandpaper to clean off the plug gap once it's dry, then look for spark.)

The plug boot adapter could be your problem... which led to a flooding problem from a crazy active choke, or too high a float level. Turn OFF the gas to start it... turn it on once it starts... That may give you an indication once you get the spark in good order.
Good luck

I have a feeling it's getting too much gas. It's getting spark just fine.

it's leaking gas out the carb when sitting and when pedaling. The float? I still havn't tried the other carb yet. I might do that.

I've tried messing with the on/off fuel switches a lot, when pedaling. Still no luck. Tried turning them to barely open, to limit the fuel supply.

I think I just need to put a hemi on it.

Turn fuel completely off. Spray a small (a second or two) amount of starting fluid or throttle body cleaner into the carb, with or without the air filter. If it's fuel...if this helps and starts, you have eliminated everything but fuel. I don't peddle...I do this to start my bike for the first start up in a day. Starts within 20 feet, in the grass.

There might be a spot of trash in the needle and seat (not the needle with the clip on it) ...causing the fuel to flow (cant be closed off) and floods.

 

[kuch]

I kind of wonder if I hooked up the needle right or not...this kit came with no instructions. Just my mechanic experience and patience. Which I'm running out of both. I'll mess around with it again tomorrow.

Thanks for the replies guys.
