Hi Guys, can anyone advise? On my G3L im using the standard 275 amal thats been refurbished having 160 main jet. It runs perfect upto 1/2 throttle but after that no good, if I use a little choke away it goes no problem.
I had a small inline fuel filter on initially after the rebuild but now removed in case that was restricting flow but no difference. I have varied the mixture screw but again no difference.
Do I need to raise the needle and if so what should be the correct setting.
Any help woould be most appreciated.
I was pointed to this Danish website with loads of information on the G3L's, there is loads of useful stuff on there such as Amal carb settings, parts lists and loads of other useful stuff, the web address is http://archives.jampot.dk/Book/
