Getting to my carb.  By  taildrag (Read 1,397 times)

Thanks Rich....I was afraid that I had to remove a panel and it is running rich.

The idle screw on the carb needs ajusting you just lift up the seat then remove the screws and the battery and the carb screw is right there under the seat. If you want to take the carb off then you will have to remove the panels on the muffler side.

Yes, under the foot rest, if your running too rich, you want to turn the air/fuel mixture ratio screw a 1/4 turn clockwise in.

Well I think I am in deep trouble. I am not very good with the wrenchs and it took me 2 1/2 hours to get that lower left hand panel off. I will set aside 3 weeks to put it back on but I cannot even see the carb. up in that mess. Tomorrow I will take the seat and liner off and see if I can see the carb. that way. We finaly have nice riding weather in AR. and I have a pile of parts in my car port. Bad timing on my part.

Have you guys see under the hood of a modern car lately? These scooters might take a little work to get to some things, but most modern cars are 10 times worse. Most V6 cars you have to have extreme yoga flexibility to get to the rear spark plugs after removing half the engine crap.
I had all the panels off the back of my 250B this weekend and it took me about 20 min to put it all back. I could see from the radiator back, bare frame.

Sorry to tell you taildrag, If it is a Linhia 257cc powerplant you have it will likely need a valve adjustment to make it stop stalling at slowdowns and Idle. Its just the nature of this engine it seems. And from what I've heard most of the 250 Rocketas and 250 JCLs have these Linhia motors. Its the 250 motor with the cylinder lying down instead of being vertical. Great motor IMHO otherwise. But this is one glaring fault they have. Some say once you do it a couple times they stop needing it so often. But I havn't got to that point yet so no comment.
