Cm870.white smoke, raw fuel smell

[Chamberpains]

Was your IFSM rebuilt during the overhaul? What warranted replacing only 1 timing or metering actuator? How do you know that the rest were good?

I'm not a huge fan of just doing something unless its warranted in some way. But you do have to look at the components of an, at least 13 year old piece of equipment and say "ya, its time to pull that apart completely and see if its all still good or maybe its just gonna get rebuilt or replace"

There are check valves and baffles on the IFSM that get clogged and wear out due to dirty fuel over many years and many gallons of fuel. Its not at bad idea at this time to start going over things with a fine tooth comb and freshening everything up.

Here's 2 video of the fuel system of your engine. Maybe they'll guide you in a direction.
