I hope your not getting sick of answering my questions, cause I do ask quite a few. I won't stop until I know everything I think I need to know aboutmy sled. Todays question is about setting up the carbs. I had them off and cleaned them and checked the jets in it (it hass 300 on all three). Then I set the slide height to .051" on each carb, reinstalled, adjusted throttle and oild pump settings. Now what I find running the sled at about 100 k/hr on the stand with the brake slightly depressed......my PTO plug is sliver on the half of the electrode towards the end (wash looks solid black on top), CENTER plug is also silver but slightly less (wash is same as PTO solid black top), and MAG side plug is fouled (wash is clearly rich with carbon in center about the size of a .05 coin). So now what do I do to level them all out? Is it common for one to be that far off when all are set exactly the same? Thanks.
