I have purchased and installed the chinese kit (80cc 2 stroke) and can't get it to fire.

I've done the following:

1-double checked wiring connections...ok as per instructions
2- tried a different spark plug
3- sprayed starter fluid into clylinder..should have at least fired if there had been spark

Any other ideas ? I'm thinking I got a bad coil but don't know how to test it ?

Any ideas or suggestions ?

Thanks

Remove the plug and put the wire on it and turn the engine over to see if you have spark.

The kill switches on most of these are pure garbage, so I'd try removing that first.

Also, check to make sure the wire is screwed into the CDI all the way and while you're at it, make sure the plug cap is secure.

You can always shut it off with the choke or by just letting the clutch out with no throttle.

To test if your getting fire you can take the plug out of the head. With it still connected to the plug wire get someone to turn the rear wheel with the clutch out while holding the plug against the cylinder. If it's firing you will able to see and hear a spark...............

Ah when I had that problem on the first try I had a wire loose. My very first guess would be the wiring from the engine to the coil. So here is my suggestion. unhook the kill switch, then hook up the other to wires. and give it a try. Has directions on how to test the coil for spark in the classic instruction section.

The other time I had this problem I did not have the coil wire attached to the coil end correctly. It takes some work to screw it into the little nipple that is inside the coil case. I didn't get it in good after I removed the wire for something else.

Give those to things a try first, If it isn't either of those take a look here....Troble shooting bicycle engine cdi and spark plug wire

When I first installed my engine I was so apprehensive I thought everything was wrong and I wanted to trash it. It's take a little time but it will all work out

Yes - check for spark.

I'll bet it's flooded. Tell me how you assembled the carb, per the given instructions?

God I love this site.

I had problems with my install and tried to get answers on the other site and it took days to get this many replies. Heck I never go this many if it hadn't been for Norman, I would still be pushing it.

When you figure it out be sure to let us know what it was. I am always having stuff go wrong the more I hear it from someone else the more I know what to do.

OK....I've re-done the plug wires and put a different plug cap on and I now have spark but no fire.

I'm pretty sure I did the carb per instructions, needle pointing downward through bottom of slide, washer inside slide, spring over cable, then cable through slit at bottom of slide and up through slide...and then screwed in place. I can't see anyway other way to do it. I've worked quite a bit on two strokes before and I'm plum out of ideas. It could have been flooded so I will let it sit overnight and see. Any other ideas.

mine did the same thing and i let it sit not because i was out of ideas but out of breath from pedaling lol. it ended up for me really simple. i gave it full choke and it fired right up. alot of people have said they never use the choke but i always have to or it will not fire

Full choke floods mine I use half choke and it firrs most everytime. My son in law showed me something for flooded engines. Take the plug out and burn it off with a cigarette lighter. Once the electrode is dry you can keep on trying. Just in case that helps any.

If you have spark and you have gas, it has to be either the mixture or the choke which is the same thing I guess. You do have the gas turned on . I know that is insulting but hey I have done it. Ran out in traffic and burned off all the gas in the line and the engine died.

Oh **** can you see gas in the line. Some of the guys have had takes so filled with crude the filter stopped up before it ever started. And did you prime the carb with the little button on the left.
