Mike Smith said he did not understand timing and would someone explain. =
Here is mine :
Knowing that you are a HAM a little lingo from that direction. Camshaft=
and Crankshaft must be synchronized. Since it is done with a cogged belt i=
t becomes part of "Timing" the engine. Likewise the injection pump must be=
synchronized to those two.On the 1.6L diesel Timing from scratch is a ver=
y simple procedure if you have the timing belt covers off. The word "Timing=
" then becomes confusing because it covers many different things , not just=
ignition.The only thing you have to do now (since you are driving) is veri=
fy how close timing marks are to specks. Flywheel right on TDC mark (that's=
were you start) Camshaft slot should be straight across (so a piece of met=
al can be used to lock it) Find slot opposite end from sprocket) Injection=
pump marks all line up. Since you are driving no need to check location of=
piston #1. You check that only if your flywheel is not marked.(almost impo=
ssible to imagine.)
In you case Ignition timing may be off ,but it is not the reason for the la=
ck of poop. Fuel starvation is your problem -- so we are back at Tank scree=
n Filter and Injection pump. The pump is the last thing we check, after you=
turn the fueling screw in with no power or smoke. As soon as you verify t=
hat you checked the above I am suggesting a dose of AD-120. For fuel line o=
n testing I use Goodyear 1/4 inch line. Blow any ants or debris out of line=
before connecting to pump. Before you know you will be burning rubber l=
ike me.
Sure is a lot of fun. Hagar.
PS: I think the thingie is the spaceship the aneroid it is an airpressure s=
ervo , that drives an adjuster of fuel metering inside pump It is adjustab=
le basically a diagfraghm.Ignore for now.Just pull the little line off the =
manifold.
