"Hi guys.... I had my boat serviced at a small shop cause the carb needed to be cleaned, while there he said i had the firing order wrong and reconfigured it to show 1,3,4,2 but he said #1 was at the stern as opposed to the bow... Is that correct? I had it set up previously to show plug hole 1 being in the front towards the bow.

If it ever stops raining we'll take it to the lake to test.

thanks
