So I have a 66cc sky hawk slant head.
Problems:
Lots of gas shoots back into the air filter. I've searched and supposedly its "normal"? I have to clean the filter before each ride and I notice my performance dropping during my 20-45 min ride.
Top speed seems to be about 12 if I don't pedal. And goes back to about 12 if I stop pedaling. Not that speedometer works or anything, but I can pedal twice as fast as this engine pushes me.
If I cut the gas off, just before I run completely out I get great performance out of it. That's how I want it to run!
Holding the clutch in, giving it WOT I can see gas leaking just a little from the crank case near the top of the rear mount.
Spark plug used to be soaking wet and black. I added more gas to about 45:1 now it's dry and black. Last time I checked, apparently I didn't have it tight enough and gas/oil leaked from the plug so the outside was wet and black but the inside was dry and black.
The small chain gear on the motor, and everything around it under the cover is getting pretty wet with gas/oil mix.
Gasket from intake is wet.
What I did;
I made a boost bottle out of some random plastic containers and vacuum tube.
Actually seems to help w/ the fuel shooting out the back problem.
Used 1/2 a soda bottle, breather filter, and more vacuum hose to try to force more air into the carb from the stock air filter.
If anything it just helps get more fresh air into the carb.
Took off and wiped the magneto. Not wet at all just some metal shavings or something in there.
Rebuilt carb.
Float seems to be working although I wouldn't know what I'm looking for.
I have no settings on my needle and no room to make my own notch to try giving it a higher air:fuel ratio.
Kill switch is not hooked up because it didn't work and I don't want to mess up the low quality stock electrical system. I'll probably install a toggle switch in the black wire at some point.
Its gotta be something not working correctly right? Everything has to be working somewhat since I have no problems starting it up or running it. It just has no power.
Questions;
1. Do I really have to take this completely apart and throw away the gaskets and use gasket maker on everything?
2. Even the head?
3. Could the stock CDI be causing this.
4.What can I do to get this running perfectly?
5. Should I wait till I get it all running perfectly before installing the NOS kit? lol
6. Anyone know where I saw that upgraded hardware kit on the net somewhere. It had all the nuts and bolts US made to replace the stock stuff.
Thank you all for everything you've already done by the way. I would have never even gotten this far with out this site. Your all awesome!
