I know not many use them anymore but does Anyone know the jet settings for a bing 55 gold cup carb on a zabel 685 cylinder reed block engine?
Having a few problems with higher revs, current settings are 215 main jet 2.84 needle jet, 6L6 needle with clip on top groove, and 85 pilot jet, I'd imagine these are way off by the way it runs! Any help greatly appreciated

I think the overall jetting is a little poor, i guess: mainjet 230, needle jet 286 or even 288, needle 6L6 with clip in he middle groove, and the pilot jet is OK 85

Is the 2stroke oil mix correct at 40:1 with castrol a747?

You can use less oil.
1:70 is enough
