HAHA, Rory is that my old KA you’re running? Fuck man I miss that motor, thing was indestructable! I loved the little farts she did and when she shot flames. If you’re wondering why its doing that now, its the timing shes running really rich. I had her richened out a little for better winter performance (colder air meant fuel burned more efficiently). Just throw 91 in her and shell run much better!
