Frustrated!!!

freshwater · #1 08-14-2008, 02:29 AM

I need help and suggestion on how to get my new 2 stroke 80cc motor started. I pedal and pedal until my heart pops and when I do release the clutch it sounds like it wants to start but it keeps dying once I slow down. I don't know what else to adjust to get it running.

The most often seen problem is an air leak at the manifold junction. If you haven't sealed that you should. It can't hurt and it often solves the problem. Also there are lots of issues with the wiring. Take the kill switch out of the wiring (they are often bad from the get go) and make sure the other wires are connected correctly. Black to black blue or green to blue or green.

If it still won't start check your plug to see if it's wet. If not you have a carb problem.

If your plug is wet and you have sealed the manifold, check for spark.

To do that take the plug out, reattach the wire. lay it on the engine's head and turn the rear wheel by hand. You should see a spark on the plug.

Let us know what you find.

Did you determine whether or not you are getting a spark yet?

First
pull your spark Plug ..if Its wet you have flooded your motor ( left the chock on to long)
or you have no spark.
If the plug is dry you have no fuel.

After you read the plug you can move on to the next step.

I know this might sound funny but have you tried starting it with the chock on? For some reason or another, I know my old bike wouldn't start unless the chock was on. The second I start to hear the motor start, I would have to slowly open up the chock until it warmed up.

I found out what the problem was! I took off the kill switch and it started right up. Thanks a million everyone I thought I had to scrap my first build. This site is the best!.

Also when I start my bike I have to try once with the choke fully on, then try again with it maybe 1/3 on.

While you have the plug out, keep it connected to the plug wire and lay it on top of the cylinder head. Release the clutch, pick up the back of the bike and spin the tire. See if it sparks. OK I just realized that was already posted...
