does this thing have sealed carb? have the valves and A/F mix been adjusted?

good points

i figured out what the problem was/is the rear brake is sticking

[Rebel]

lol, well that is a entire other ball park.

Has anyone had to bleed the front hydraulic disc brakes on one of these things? I tried to do it like i would a car but that doesn't work apparently

[Rebel]

Brent did a tutorial for that;

for a small system it takes a lot more pumping then a car does

thats why i like to use a vaccum bleeder
depsite the reviews this is what i have and use

i have used it on my scoots the wifes car and even the 26000 lb drill rig at work
it works great when you have to put a vaccum on just about anything to include the vaccum petcock to drain a fuel tank

I used to have one of those, think I lost it in a divorce. I went back to just putting a hose on the bleed valve and into a glass jar, then pump it through keeping the top reservoire full.

I've heard of people that pump it up from the bottom too.

Main thing is to get all the air out or the brakes will not work well.

i want to add these to the scoots

what i would love is one of the new power bleeders where it adapts to the master cyl and forces fresh fluid thru the system

[Rebel]

this was what I had, worked well I just have a hard time talking myself into buying nother.

Really though, if you put a piece of clear tubing on the bleeder valve and into a glass jar with perhaps half a jar of brake fluid in it so that the end of the hose never comes out of the fluid, you can bleed it by yourself, air should not come back up the line and if it does you will not have a solid pedal, don't forget to tighten the valve though.

Damn, that tutorial was exactly what a guy I work with said to do

[dcramer27]

So I think I have figured out why I don't idle, im thinking either the float is no good or there is a clog or one of the jets are no good, so for $10 I am just gonna buy the rebuild kit and be done with it

[Rebel]

is the float included in the rebuild kit?

[dcramer27]

it sure is, hell of a buy for $9.95

[dcramer27]

So I opened up the seat and lifted up the carb inspection plate and to my surprise the choke was just dangling there broken, I guess that would explain the idle issue I was having, went ahead with the rebuild as well

[dcramer27]

runs much better now and my electrical problem is solved as well which i found weird but cool
