With a nice day i decided to break in My HPI Firestorm. I ran the heatcycle/traxxas method in the past with no issues. I even broke in my OS cvrx in my EVO 3 last week with no issues. Today I ran 2 half tank runs at no more than 1/4 throttle letting cool in between both. Then 2 half tanks at no more than 1/2 throttle letting cool in between. on these runs I only had to lean HSN 1/4 turn to maintain temps it the lower 200's. On my next two runs i go half throttle with full throttle mixed in. When it was time to tune the motor i leaned out to maintain smoke from pipe and temps in the 220-230 range. The problem when trying to hold full throttle or accelerate fast the motor would sputter and die if I did not let off. It seemed like a lean symptom so i richened and same thing happened and my temps dropped to low,I always had plenty of smoke. I also noticed fuel leaking from crankshaft when cleaning afterwards. could my HSN be to rich or lean? and is so witch one.
