Idle issues By dozer187 (Read 512 times)

So ive got a 150cc powermax stock aside from exhaust replacement cuz original fell apart and a tuneable oem carb. Lately my idle has been high when riding, i checked all vacuum lines and couldnt find a leak, all gaskets are good as well. Im thinking it could be valves needing adjustment, im also still using original airfilter and im at 3500miles so im sure its filthy, is there anything else im overlooking that could be causing it?

If you have checked every thing just turn idle down. It could be the spring under the screw for idle adjust has got weak. (do not confuse that with the air-fuel mix) You do know how to check vacuum leaks....a spray bottle, mister, carb cleaner, ether, just about any thing that can be misted all over the vacuum lines and carb/manifold/head. A leak will change the rpms, sometimes faster - sometimes slower. I usually use ether but as stated even water works there.

A dirty filter will want more air to keep the mix right. Better change it and yes check the valves, the exhaust especially will close up.

Already checked the idle adjust screw, ill do a valve adjust probably tomorrow, gota open yhe airbox to see which filter type i have. Is there an easy way to check if the enricher is working properly?

For the enricher with the bike cold take off the enricher and apply 12 volts to the two wires at the plug. with in 5 min the little pecker that goes into the carb on it will extend. What happens is cold it does not block a port that allows extra fuel into carb. After a few min hot wax inside it forces that little pecker into that port blocking it and now the "choke" is off. With the engine running there is always 12v on its wires.

I just blocked off mine completely. Really helped me.

Do one change and check results.

You blocked off the enricher? How?

[jct842]

Compared to a enricher working right and blocking it ......it is impossible for the blocked one to run better. Blocked you have no choke. AND.... there are choke kits and I don't know where they can be had. Enricher are pretty reliable and super easy to replace 1should they fail. I never ever had the urge to remove mine I rather like how they always work and no fussing with choke. Those Chinese knew what they were doing with it.

You guys probably have no idea how many of those scooters in the third world countries all have the enricher working perfect.

All they do is stop the extra fuel for when bike is cold and warming up

If blocking it helped then you have another problem.

Please explain. Are you speaking of the fact that I might not be getting the correct voltage to the auto choke?

I agree. I have problems with the auto choke since 4 months after I bought it new back in 2012.

The shop I bought it from couldn't figure it out. But they couldn't figure out much of anything.

[jct842]

Am sure you checked voltage before you blocked. Could be wrong pilot jet. Or setup of carb.

Again I repeat....manually blocking or using enricher does exactly the Same thing.
