I wish
My cam is an old Hughes (2004); 276/286/110, 230/[email protected], 549/[email protected] arms
she runs an ancient 750DP on an AirGap
To run that slow, I dial back the IdleTiming electronically to ~5*. leaving the Transfer slot sync alone. Normal idle is 700@14*. The heavy flywheel keeps the tic-over stable; just like it does on an old JohnDeere.
