I rebuilt my Mariner 60 twin and it's been running on a really oily mix, around 35 to 1. It needs choke to start and won't come down to a nice slowish idle. It sort of comes down, then starts to slowly falter, then dies over a course of 10 seconds or so.
The idle mix screws definitely affect the idle, I can screw them in or out and cause it to run rough, they're set at best idle.
Engine is synched as per manuals and all checks out there.
So, will a really oil rich mix cause an issue like this?
