So the Christmas vacation period is over and those long working weeks are in front of us until Easter.
As mentioned my visit at the Registration Authority was succesful and I got my licence number, BUT in the Annual Control Inspection she failed. The front brakes were too much mismatching so I have to fix that a go back for a re-test.
Anyway grandchildren, children, wife and me had some rides during a sunny but very cold Christmas Day.
Now I have taken the left side front brake apart and discovered that one of the cylinders are stuck, new one is already ordered from my local jeep parts supplier 250 km away.
The finished product is always a great pleasure to behold! _________________ Wes K

Hi again all
After the discussion in the thread "M38A1 Cold start problem" I ran around to the garages in the neighborhood asking for a fuel pressure gauge. The guy at the last garage said: "Why don't you go to the local auto parts store, they have a fuel pressure gauge at a reasonable price." So I did.
The bearable price was about US $10 = SEK 100. A swift fix for the provisional connections and I found out that the the fuel pressure was about 3,5 - 5 PSI, both for the original fuel pump and the electric fuel pump.
Another guy at another gararge adviced me about this combined fuel pressure regulator and fuel filter called Filter King, so I ordered one on the Internet. This one was already from the start adjusted to 0,13 BAR = about 1,8 PSI, and also preperred with an outled for a pressure gauge.
After some problems with leakage at the connections, I finally got the filter/regulator running properly. I have now taken the electric pump away and I am only running the original pump.
I have also got familiar with "the cold start problems" in my Solex carb, and almost tamed it, she will start now after the third cranking, but I still find a lot of soot in the exhaust gases when the engine is cold. Is that something I have to live with, or is it some adjustment problem, or maybe just too much choke?
I think I have tamed my Solex now. I got some very good advice from "skyjeep50" regarding cold start, and I feel I manage now. When the engine is cold I crank until it starts, which takes about 10-12 seconds, and then she runs. I think I was a little too considerate of the starter motor initially, it is new you know, and I want it to last as long as I have the jeep.
I have also performed a compression test with the following result:
Cylinder 1: 6,5
Cylinder 2: 7,5
Cylinder 3: 7,3
Cylinder 4: 6,5
I really don't know the sort, maybe it is kg/cm square, but is really doesn't matter. I can see that cylinders 1 and 4 are equal, 2 and 3 are equal. They differ a little too much in my opinion, but I suppose I have to live with that, anyway until something worse is happening and I have to lift the top. _________________ //Jan-Olof

After my struggle with the difference in compression in the cylinders I talked to a couple of skilled car mechanics, and they recommended to run the jeep over the summer and then do a new compression and leakage test. They say that after sitting for more then 8 years, she may cure herself after running a bit.
In the meantime I have ordered and received a brand new canvas top from John and Mary Worthing in UK. I had to prolong the top bow "fork" 60 mm in order to make the top fit better. Unfortunately there still is some mismatch of the side curtains and the doors, but I suppose I have to live with that.
My local jeep parts dealer provided the WS brackets, but the horisontal and vertical rods I made myself.
I have also installed front axle hub nobs in order to reduce noise and fuel consumption, but I have not yet noticed any difference in neither.
Jan-Olaf,
Have you driven other jeeps to have a base line of noise to make comparisons with? _________________ Wes K

No, to be honest it was 45 years ago I frequently drove a 1947 CJ2A and a 1951 CJ3A, but I can't remember the noise was that loud it was impossible to talk to the person beside me.
The noise differs depending which gear and what speed I go, which of course is obvious.
A lot of noise is coming out from the gear shifter, and second gear is tripping out if you reduce throttle without holding the gear shifter steadily. I have read many other threads on this forum about the same problems. Engine was refurbished in 2002, but transmission haven't been touched for the last 55 years. _________________ //Jan-Olof

Jan-Olaf,
What you describe is a very good indicator that the synchro, the bearings, the pilot bushing all need work.
I have noticed that after 60 it is more of a problem to hold a conversation anywhere with my degraded hearing! _________________ Wes K

If you have to wait until next winter to rebuild the tranny/transfer
you might consider getting the rebuild parts ahead of time, specifically
for the shift tower. Poppet balls and springs, gasket, etc., and rebuild
the shift tower over a weekend.
It might help jumping out of 2nd gear. Might. Won't help the noise.
But it is something that will have to be done eventually and you can
do it without removing anything except the floor pan.
