Got it running smooth! I think I need to adjust the valves again though. I can here it ticking now...

Another quick question...
What should the throttle adjustment be set at when adjusting the fuel mixture screw?

So I turned the fuel mixture screw all the way in and back out 1 and 1/2 turns. got the scoot running! Then I started messing with the screw and flooded it again.
I pulled the spark to start airing it out, then pulled the carb to check the needle. Needle was fine. Since I pulled the carb and the fuel was disconnected, I cranked the motor until there was no fuel spraying out of the spark hole.
Now I'm waiting 20 min or so to try again, starting with the screw 1 and 1/2 turns out again.

If its flooding so bad might have a stuck float needle valve,,or maybe the pin that holds the needle valve was not put in correctly,,i would take the float bowl off and make sure the needle seats up into the orfice properly and blow into the fuel line as you push the float up,,and when the needle gets pushed all the way up,,you should not be able to blow any air through,,thats how i check em.Then turn it over a few times without the plug,,clean and reinstall the plug and give it another try. BTW-Make sure the crankcase is not full of fuel as a sticky needle valve will eventually flood out your crankcase oil also causing hydro lock and other not so pleasant things  One of the first things I did when this problem arose was check the floats and clean the carb. I haven't tried what you said with the needle. I'll try later today. Thanks! |

Well I did as you said, and tried to start it again. Still wont start, still flooding/flooded. I'll try again tomorrow when I know for sure that it's aired out. I'll post my results.

How long does it take to air out the fuel?

I just got done setting the valves. Both were set to .003". I changed the exhaust to .004". I took more of the plastics off so I could reach the fuel ratio screw. For good measure, I decided to turn the screw 1/8 turn, then tried kick starting it. It wouldn't start. I then realized I turned the screw the wrong way. I assumed I flooded the engine. I've pulled the spark and I'm now letting it air out. I have turn the screw the correct direction(clockwise) 1/4 turn to correct my error. Hopefully I'll be able to start it up soon!

In the old forum there used to be a sticky thread about different weight rollers/sliders and the results. I'm interested in getting a variator set, but I don't really know where to start with the weights. The set I'm looking at has 12g weights with a 1000k spring, and that seems a little heavy to me.

Ok. I will be home in about 4 hours. I'll start with adjusting the valves. If that doesn't work, I'll pull the plug and report the condition.

If my engine runs fast when I first start(cold start), then slows down to slow idle after a couple minutes, wouldn't that mean the enricher is functioning properly?
If the enricher is functioning properly, and the engine bogs down and dies after the enricher is fully extended and the engine is in slow idle, wouldn't that mean its getting less fuel when it stalls?

So from what I've read on how an enricher works, it cuts off the extra fuel after it's warmed up(2-3 min), which is when my scoot wants to bog down and die at low idle. So from this, I can conclude that my scoot won't run without the extra fuel.
The only way I can describe the bogging down is when the motor slows down to where is should idle(low idle), it will continue to slow down and stall. If I give it gas to keep it from stalling, it stutters with very little power until it picks back up to a higher rpm. Can improperly set valves cause this? If so, can someone explain why/how?
I'm very interested to learn how to maintain my scoot, but none of this knowledge will stick unless I understand the mechanics behind it.
Thanks a bunch!

You could try a 2.2ohm resistor between the lights and the battery which would drop the voltage from 12 to 9.7, but with the stator and motor running that voltage spikes I think. Mostly correct! However, when running electricity off the battery, you won't see a voltage spike. From the stator(alternator), power goes to the rectifier(regulator) which cuts out the power spikes and converts to DC. From there the power goes to the battery. Power off the battery should be a steady voltage. |

I was hoping someone could provide some other ideas I could try if the valve adjustment doesn't work. Any insight greatly appreciated. Thank you!

I'll give it a try tomorrow afternoon and post my results. Thanks!
