So the mark timing is on 282 in the video or 278?

Im 90% sure the video was 278..

WHICH PLUGS LOOKED MOIST/WET?

WHAT IS THE PLUG GAP?

The build up is from the crappy race carbs which look cool but work bad under 3000 rpm with big cams, but thats' ok, it s a "race car".  :thumb:

Now that we have the idle timing correct whatever it may have been at, the plugs "may" not get so black, however, my guess is that the carbs will need some tuning.

The dirty plugs may have been causing the miss and popping you heard.

At this point, I would clean the crap out of the plugs, then set the gap to .038" then reinstall them into the same holes.
.

3 and 6 had a slight bit of moisture but i guess the others could have dried..

Plugs are NGK BKR5E

That is what the builder put in them, preset gap is 0.35 i believe..

IS THE TIMING MARK ON 278 OR 282?

ok, thats what i thought . i was having you advance it slightly from 278 while it was idling to see if the rpm increased.

i think you should put the new cheap oil in and set the timing to 278 and take another short video . dont forget to take a few seconds under the hood and behind the car.

dont forget to hold the throttle farther open after it starts.

if it runs ok, we should do the test where you advance the timing slightly at idle.

verify the gap . .035" is ok.

Actually 282 was the last because i marked everything just in case..

It began to idle rough after we moved the wires and distributor to gain clearance to rotate the housing..

As it is now, timing is dead on 282..

But i guess if it started to ingest water again when it hit temp i spose that could explain the change in idle and oil pressure change up and down yeah ?

Ok, none of this makes sense.

I still need to know what friggen number the white line is drawn on . If you don't tell me I can't help you.

It's on 282.

ok, this is where the mark was in the video.


Uploading a video of it now running at part throttle, don't think its missing at all.

When looking at the engine, the 278 mark is a few degrees to the left of the pointer.


if it was to the left of the pointer as you faced the engine, it was actually firing on 282 based on your description . if your description is wrong, the timing will be wrong but still fairly close.

based on this info, i would leave it at 282 and fire it up with the new oil and filter if you plan to try that.

if you are going to give up on it, then write a note that 282 is the correct setting for the idle.

10 quarts (9.5 liters) of oil and 2 filters..

How many times do i need to flush this out so i can see if its another leak before i waste another $150 on oil  :thud:

Don't use those race plugs on the street ,just normal NGK plugs . As Barnett said no good for under 3,000 rpm and street use .

Hey, since they are all equally black, we at least know that all the carbs are jetted evenly  . :leaving:

Yes it is running rich .  Does it have a MSD 6 AL box  or similar ? . I would run a 5 heat range NGK plug till this thing is all sorted .

I told him on page 1 it would need a box . I had him buy the Pertronix II instead of the III with the expectation that he would get the MSD box, however, his finance minister has just kicked him in the nuts for whatever reason  :lol: so I kinda doubt the box will be forthcoming in the near future.

My plan was to also have him turn all the idle mix screws in 1/4 turn to see what that might do.

That cam is 236/242 @ .050 and has steep ramps so I was hoping to get some vacuum by running a lot of initial timing and a start timing retard box if necessary but we haven't gotten quite that far yet . I am actually surprised the thing even idles with those carbs and that cam.

Oh, they also don't seem to have a choke, but I guess it's not needed when massive amounts of raw un-atomized gas is being poured directly onto the plug.  :lmao:

So did she intentionally try to kill your new $90,000.00 Turbo DIESEL Land Cruiser by putting 96 octane gasoline in it?

Ok, here it is in all its glory.

https://www.youtube.com/watch?v=X9E1Gd0QKYQ&feature=youtu.be


TIMING

Ok, the idle timing is very good . It may not be possible to improve on it . It is not missing so that is good . It was missing before because it either had water on the plugs or because they were so black with carbon.


JETTING

It is possibly a bit rich at idle because it shouldn't idle quite as well immediately after starting a cold engine . We will have to check two plugs again later.


MUFFLERS

They sound too quiet and gay to be performance mufflers . You need straight thru mufflers.


MSD BOX

Buy one.

With custom white exhaust smoke...  :thud:

I agree, it needs side exits...  :lol:

What do you mean white exhaust smoke?

Did it not do that before?


It might go away when the engine and exhaust system gets warm.

If it lingers for several seconds and makes a smoke trail, it is oil . If it disappears right away after it comes out, it is water from condensation in the mufflers or from leaking intake or head gaskets.

If you put side exits with straight thru mufflers you will get arrested by the first cop you go by .  :lmao:
