After thoroughly cleaning carby and fuel line, ran the mower for good 25min and no issues with stalling. See how i go next mow.

I noticed i have no more travel on the screw adjustment for the cylinder reel and she is now not cutting well. Have ordered another bedknife as the old one may of been sharpened over the years to a point where it is too short for the reel to contact. Will send the reel and new bedknife to the sharpeners. If i am missing something or havent considered other options, please let me know.
