saying for us to truly syn this Engine

saying for us to truly syn this Engine with this tool in its current condition

with this tool in its current condition

with this tool in its current condition we have to actually have this one say

we have to actually have this one say

we have to actually have this one say minus one and this one say + two what

minus one and this one say + two what

minus one and this one say + two what we're adjusting is those adjustment

we're adjusting is those adjustment

we're adjusting is those adjustment screws that we talked about earlier here
