Centrifugal Centrifugal Clutch in oil

[StreetPlanes]

Can't say for sure but there's a very slight chance that inverting the engine might have caused the needle in the carb to fall out of its seat. That would allow gas to leak out of the carb.

That said, check your spark plug wire and ask around some more before you go tearing into a new carb.

not running right

Check your oil, you may have filled your crankcase with gas.
I did have that problem with the little Hua Shua once, had to drain and refill.

as you can see the hairpin is still here...
and what is the dial circled in red from the picture?

But there is one problem... I'll start a new topic to tell u what the problem is.

the problem is...there is no need to start a new topic to talk about the same bike.
Don't get me wrong...this is a great topic. lots of info. I can't wait to see these 4 strokes become dependable. Let's just try to keep all the info together.

Ok, I really think this is a carburetor problem...

Why?
1) I believe fuel doesn't get deliveried to the cylinder that's why it stalls when throttling
2) it seems like the engine "use up" the fuel, then it stalls.
3) Initially, it ran for about 30 seconds then stalled. Then it ran for 10s, then stalled... 3rd try... I have a hard time to start... stall within seconds of course....

OK... so this stall problem is related to the carb.

then I open it up and rebuild it. here are some pictures:


I cleaned the whole thing w/ carb cleaner. the fuel valve is ok, the overflow cirucuit is ok, and the nozzle to the venturi is also ok. needle still look sharp and good...


but when I put them back together... it's still have this stall problem! any1 help?

You need to replace the bolts that you removed from the cylinder head when you removed the gas tank. You may need to get shorter bolts or shim the originals with washers so they don't bottom out. The piece that you have circled is for mixture adjustment. It looks like you have it set at leanest setting. Maybe try moving it opposite way for richer mixture. Just a thought.

 

[MadPC]

so you mean I need to put back the bolt that hold the original Tank from Honda? And that may solve the stall problem? WHy is that?

 

[Butch]

Sorry bout that. Nothin to do with the stall problem. Just thought you might start leaking oil if you didn't put the bolts back on your valve cover.

so does any1 know how to how fix the stalling probleM??

It's getting worse... the engine won't run for more then 10 sec now....

So basically the engine is running until the float bowl drains of its excess fuel. then runs when it refills.

you might have a fuel problem, check your fuel line, or a clogged filter, or maybe your just forgetting to turn the valve to on. if it starts and runs for a time then it has to be fuel. or your choke. take the carb off, clean it out, replace your fuel line add a new filter, and check the fuel valve for blockage
