July 11, 201610 yr Author ok fitted new jet - shes still playing up - starts easy on choke revs hi then dies when choke is closed. it had blocked jets that started this whole journey and we have cleaned the jets with carby cleaner and oxy tip cleaners (gently) and no go. is it possible to reassemble the carb and get it wrong? thanks in advance for any help on this one.
July 14, 201610 yr Hi Reginald, as we all know, it's easier to get things wrong than it is to get things right. i had similar with my 125 and it turned out to be a simple misunderstanding. The idle mixture screw is in this case for fuel and not for air. Screw it all the way home and then back out 1 and a half turns to start with. Then screw in the idle screw so as the motor runs at a higher idle speed than normal. That is of course if it will when you turn the choke off. If it won't run without the choke then there is something else amiss. Did you replace anything such as the needle, needle valve, float assembly ? Have you checked the float level ? Did you replace all of the small O rings on the idle/mixture screws ? What about the fuelline/filter ? Did you rebuild the carb referencing an exploded view making sure that all of the components were in place ?
