10s will work until too much deposits build up. So they will run. If ever you find there is problem with power (one cyl not firing) try to avoid throttling through the problem unless you are running premix.

Sorry revsummitho28 you are wrong the sdi's run br9ecs and the carb's run the br9ecs-5. Different gaps br9ecs .030 gap and the br9ecs-5 .018 gap.

I dont think the sled will run good with the 10s. imo

The br10ecs plugs are a colder plug and pregapped at about .030 ( .8mm ).

The br9ecs plugs are gapped at .030 also.

The br9ecs-5 plugs are gapped at about .020 ( .5mm ).

and will have #6669 on the box and these are the ones your 800ho carbed sled should have.
