OK I will post a pic of what it looks like, But this is the one I had been using with the 0.028" and the 0.042" before the the 0.026" and the 0.041"

Can these washers be reused?
They are a tapered compression washer or something IIRC.
I'm thinking not???

Then I'll put a new one in and try again. I'll kill it on my way toward to upward side of the hill by my house.

I would say this plug says rich idle and lean WOT if it had been cut during a WOT run. It was not.

I am going to put a new plug in close the return line some and try again to kill it after a good WOT run.

Here is the new plug.
0.026" idle
0.041" main
Return valve half turned.

Similar performance, but I got oil leaking.
Guess it is time to regasket and stud the side cover.

One.

If you look at pic 3 closely, it looks like there are specs on the porcelain. That is bad right?
And this whole plug looks pretty lean, but I can't seem to hold WOT long enough and also get timing correct so that I don't have to push it for blocks after I kill it.

---------- Post added at 06:18 PM ---------- Previous post was at 06:11 PM ----------

I was at 42 mph, which is 6000 rpm if no slipping.

---------- Post added at 06:33 PM ---------- Previous post was at 06:18 PM ----------

AND the low end is there. There is no easing into it. When the clutch engages, the buggy jumps.

So I drained the oil. Again. Nasty Stuff. More flake than my Tuxedo Black Paint and almost as dark. This time to change the side cover gasket. May or may not be the source of the leak????????? Seems I saw a drip from the valve cover too.


What is next, go back up in Jet size. Start over with 0.028" and 0.042"???

Bad Side Cover Seal?
Poor piston rings? BlowBy
Faulty breather (PCV) valve?

Time to remove the TC, Side Cover, Open it up, Inspect the internals, regasket, and stud.
Open up the valve cover, check the lash, check the PCV valve, and seal it up.
Take the flywheel off and check the timing key.

Once I'm happy with all of that I can get back to jetting I guess.

So Started taking the TC apart and found my first problem as soon as I got the cover off. The bronze bushing is broken. Split straight across. It was loose inside the TC cover, meaning it came off the shaft. I'm sure the the belt has taken some abuse. My phone is charging so I share blurry pics later.

I'd like to say the beastly engine just laughed at it, but it was probably some alignment issue or a ???

Probably the sickly monster I built is too much for the 30 series?

I've still got two more backup bushings.

Ooohhhh. It's my turn to roll again. I'm playing "what else is broken?" It's fun.

TC Belt is 1/32" Less than the original 3/4".

Pretty sure the oil was coming from the dipstick plug under the TC. It was loose.

Too Tree hours later and I'm done picking gasket material off the block and side cover.

Need one of these and a multi meter and a nut from a store and weld the nut on your exhaust near the engine. Connect multi meter using volts 1.0 rich and .1 being lean. Better than looking at plugs in my opinion. Now you'll know what at idle what at wot what at cruise. http://www.scirocco.org/tech/misc/afgauge/af.html


I've looked into this before. Cool Stuff, pretty easy.

I'll send you the $10 if you make it.

Sounds like you're going lean at high rpm, like you are draining the float bowl.

I'm guessing that trying to mod the float height on a carb where it is nonadjustable (I think), would only delay the problem. If at high RPM, the engine uses more fuel than the pump is providing, I could,,,,
1. Loosen gas cap
2. Close Return Line
3. Try Gravity
4. Bigger Pump

Does this plan of attack fall in line with what you would do?

So the Dorman Exhaust Studs....

No Instructions...

Assuming the square part goes on the outside (for grabbing and turning).
The nuts only finger tighten about the 1/3". I assume the thread on these nuts are "special"???
Since they are not for this engine's side cover and they need to be tightened 2.5X what I can do finger tight, I am paused.

I can't find Torque specs for these.

Says M8 25 ft lbs???

Class 10.9 metric M8 says 24ft lbs.
https://www.swtc.edu/Ag_Power/diesel_engines/lecture/Metric torque values.pdf

Not sure what class/grade these are.
http://www.dormanproducts.com/p-274-03411.aspx?origin=keyword

I looked up the Ford torque specs that these are replacements for and found 18 ft lbs for the nuts and 9 ft lbs for the studs.
