the misfire is very intermittent. It'll idle smooth for a bit and then miss. I'll give it partial throttle up to @1500rpm and it'll increase the misfire frequency. There is a point when the engine seems to really change the timing when cracking open the throttle and that's around 1500-2000rpm. That position is where the misfire happens most frequently. Running it at 3K or higher rpm's and I'll occasionally hear a slight miss out of the muffler but nothing near as bad as the lower rpms.
