Default Challenger carb settings

Hi all,
having problems with the jetting on my MX5 challenger, have looked at amal carb sites, they all have different opinions. So what main jet/pilot, and which slide do i use on concentric 930 / 2

Default

Start with 300 main , needle net 106 needle on middle clip and a 35 pilot
Then play from there. Oh and cutaway 3 on slide I think isstandard

Default Carb settings

Hi,
thanks for the info, at least its a starting point, the bikes in question, were bought from US as derelict desert racers, so the carb settings were not standard, so thanks again i can get on with the tuneing.
