Eddy 1405 tuning advice

To be honest Rob, I couldnt say and i never got any vac readings when issues arose. I got speed but no vac.
Weird i ran this carb last year "fine".
Also "losing" power with rod change?
As i mentioned i didnt touch timing at all. It's at 16* initial
I'll try stabbing at the primaries tomorrow and report back.
Can you tell if the bog is on the primaries or the secondaries? Get a feel for when it hits the sceondaries and stab the primaries HARD without opening the secondaries and that will tell you. But....it might also be on the secondaries as well, so there may be two different bogs.
