I posted a little while ago about my carb being blocked, couldnt solve it so i just went n bought a new carb. now the bike will start no problem. i left it running for a good 10-15 mins on idle and when i go to open the choke it cuts out and when i open the throttle it cuts out aswell. i must be making a stupid mistake which i'll probably kick myself for later but have no experience with carbs so need help, any will be much appreciated :)

All I've been told is it might be were I need to adjust a screw. My new carb is patten it isn't the same as my original one and I don't think its adjusted right.... How do you adjust it??

Probably the mixture screw maybe running lean, if you can find the screw start by screwing it in all the way in then back it out 2-1/2 turns to start with then try it and adjust from there hope this helps.

Yeah....you've got to make sure it's got the correct size main jet in there and the needle is in the correct groove and the throttle cable is adjusted correctly.....info that is normally in the Haynes manual. You could compare the needle setting with the carb you took off and also that the main jet is the same size....assuming the new carb is exactly the same as the one you have taken off..... :)

If it's a pattern carb, as in a cheaper copy of a factory one, it will still have all the screws and adjustment in the same place, but some of the turns might be slightly out, the Haynes settings should still get you somewhere close.


if by pattern you mean a completely different carb that just happens to fit your bike,then you are in a world of pain! :crybaby:
