No 1st start, dry spark plug, engine doesnt suck fuel, doesnt seem to "breathe" at all, at wits end...

Hi everyone,

So like the title says I am at my wits end with this little Chinese 80cc 2 stroke kit.

I simply cant get it to 1st start.

Engine has spark, but it doesn't want to suck fuel. Spark plug is dry. Even if I spray fuel into the carb, or even in the cylinder itself, it doesn't start. Not even a putter, a pop. Nothing. Zilch.

I opened up the cylinder, carb, it all seems fine. Bowl is getting fuel, but it doesn't go past the carb. Compression is good. Fuel is good.



Does anyone have any idea why this engine won't start? Is it possible that ports are not milled correctly and that the engine has no capacity to move air around? It doesn't seem to breathe/circulate air at all.

If I remember right he said it has spark.

Last thing to check is if the clutch is slipping when you're trying to start this engine, when they're brand new they are rather stiff and hard to turn over. Make sure there is when released a little slack in the cable.

From everything stated in the OP, I wonder if the plug is grounding out. Key words are, sprayed fuel into the combustion chamber and nuttin. Compression being good it should have at least popped off.

There does seem to be a bit of shipping tape fastener use, very nonconductive.

OK, let's determine if the timing on the motor is right. Pull the plug and put a straw down the spark plug hole. Turn the engine over until the straw is at its highest point. Then remove mag cover and take a picture of the end of the crank with the mag on it. Remove crank nut first so we can see position of mag on the crank. Then post picture here. TY
