About 58 degrees this morning and no go. I gave her a couple long cranks and she didn't have any signs of life. I didn't want to kill the battery so I hooked the strip fuse back up. Lots of unburned fuel in the system! Fired right up with an RPM spike and lots of smoke.


So I guess the 603 will simply not start cold like a 617 will. Interesting bet it has to do with the head design.
