Congrats Jari, the car is amazing now after all your work!

That would be the shortest test drive ever

Whats with the red license plates?

Yes, nice rumble on there. I wouldn't be able to just go back into the garage at that point!

Well, idle and mixtures are not adjusted yet precisely, throttle linkages also need some attention. It will smoothen the rouhg idle little I think.
It has 274 degree (six pack) cam. little bit more lift too than original ram induction cam.
I am very satisfied with the sound Just what I wanted.
I am eager to know what that motor is capable to perform, when original motor made 375 hp and 495 ftlb of torque

Thanks Wizard! Those are 1961 Wyoming plates (never used back then). They just fit so great with red hub cap inserts, front, rear and side emblems and red interior

It had a broken front clutch assy, actually the hub is broken and you cant fix that securely.



Perfect example of front clutch ring land breakage from the groove to the beveled edge that i mentioned before. Without that beveled edge (that is completely unnecessary btw) it would have lasted forever. I can't remember how many CI Tflites I saw with that damage, including my own.

What are the symptoms that the trans makes when those edges are broken off?

It is nice summer here already, I drove the G out and did some test driving at my own yard.
adjusted ignition and carbs.
I was un able to put timing to 5 degrees, I had to it by ear (wich i usually do anyway) becouse the strobo shows out of scale
somewhere around 30 degrees advance.
I think the damber (that is old) its rubber has moved or something. Gotta find a new balancer.
I got lambda sensors in both pipes, they show normal values around 0,900 when idling
but on 3000 rpm the right lambda (left carb and second in line) goes very very lean under 0,100 when the other stays around between 0,700 to 0,900
Engine sounds normal though.

Here are the reasons i have heard so far from my pals
-fuel pump is not efficient enouhg (no preassure left for the carb behind)
-carb float level is not correct and goes lean
-leak in exhaust manifold or gasket and it shows as a wrong result
-lambda is broken (pasic aftermark one for volvo)
-this is not reliable method to measure rich/lean. I should do it on the road or test bench
-I should have wide band sensor, not simple two wire sensor

So I'll check the floats first, then switch lambdas...

If your harmonic dampener is stable (not moving), you can find top dead center through the #1 spark plug hole and then make a new mark on it. Then you will be able to time it like normal without buying a new dampener....yet.

Your friend is right. You must use a wide band O2 sensor to check carburetor settings. The others don't give you enough of a range to give adequate information. Very, very lean on an EFI car is only slightly lean on a carbureted car. EFI O2 sensors are like on/off switches. If you are slightly off, they just say off. But it does tell you that you are at least a little lean for some reason, but don't try to gauge how much lean from that info. Manufacturers use these extremely sensitive O2 sensors to position the setting very accurately to get max fuel efficiency, and don't care about any information that is a ways off. But carbureted engines will typically run through a whole range of too rich & too lean conditions throughout the different weather & throttle settings so you need to test it with something with a wider range on it.

Thanks Nathan, that confirmed what my friend told me. I'm not so worried anymore

Sure. That said, it is always best to be a little rich rather than a little lean, so it would still be good to figure out how to richen it up a little.

I re adjusted the floats, made sure automatic choke works. Now when the engine is warm it runs nice. I even drove little bit on street
and it runs super nice and follows the pedal. This car is not insured nor registered so it was really short test.
Now lambdas give same values.

I got a tax bill from the coverment on friday on line, paid it and was able to register it to Finnish DMV register and got old style Finnish plates. (not wide EU-plates)
picked them up right away.
Whole process (verdict about the car tax) took about 2 months and cost me 21,87 euros (what a waiste of recources)
It is in antique vehicle registery and I am allowed to drive 30 days a year with in expensive incurance. About 35 euros a year. Not too bad.

Earlier in August i attended local car show only about 1,5 miles from my garage.

300 works and drives very nice now, its a best FWLcar I've driven so far. I got slight problems with vacuum when the engine is hot, Its been quite hot summer here too.
Engine stalls easily when using brake and sifting from N to D or vice versa after slow traffic. In hi-way use no prolem.
I am thinking to block exhaust elbow to intake couse I'm never gonna drive in winter time.

So I quess I is time to put on end to this thread. Restoration done.
I am going to attend to car show in Lahti in late september and few other in next spring and summer.

I got a 59 Royal Lancer waiting for my attention next winter but it'll another story.
