Linhai Aeolus Passportz 50 rebuild issue By frankenscooter (Read 391 times)

I picked up a Linhai Aeolus Passportz 50cc basket case for 50 bucks,

I replaced the ignition and the gas tank, rebuilt the engine with a 50mm bigbore kit with A9 cam, last night was the test start. I did get it to run for a while, but it would cut off at high rev. this morning I started it again, it ran for a minute or so then died and wont fire, I changed the coil and plug and cdi as I ran thru possibilities, then checked gas, it is not pouring out just drip, could the new petcock be faulty? what other things should I look for

thanks

Couple things come to mind,,, vac line leaking and not pulling enough to open the valve,, bad valve ,, screen filter in tank plugged,,,

[frankenscooter]

Excellent ideas thanks, I will have time tomorrow, will,let you,know what happens

[frankenscooter]

Ok, replaced vacuum line and fuel line and it started, now I will do the carb work, thanks

No problemo ,,, sometimes it takes somebody else looking into the fishbowl instead of out

If it runs decent don't fu(k with the carb,, put a few ounces of sea foam in a full tank and go for a ride,,, enjoy

Upped the main jet to a 96 seems better,

I have a question, becaue we have the same scooter, when you changed the plugs do you need to regap them? I bought ngk plugs and im not sure if ui need to regap them i bought plug number c7hsa?

[christopher]

does anyone know if a new spark plug from ngk c7hsa needs to be regaped or is it already gapped for my bike!
i also own a lin hai passportz 49.5 cc

I would check the gap,,,I've had plugs that were "pregapped ". That were a mile off
