Re: Clogged Yanmar mixing elbow?
before removing put the inlet in a vinegar bucket...start engine and completely suck all the vinegar till it starts coming out...
let sit for at least 24 hours...sometimes up to 48
then flush with distilled water(cold)
if this DOESNT help you must dismantle and manually clean
this shoud be done as regular maintenance and you save a lot of money versus buying industrial engine "cleaners"
I did this on my last engine an atomic 4 and the difference in max loaded rpm was very noticeable
power loss and parasitic loads can come from many sources on an engine, fuel, air, cooling system, belt chafe...etc...
