Had the head off which neede the throttle disconnected. While re-connecting the throttle cable I noticed one of the strands was loose so I snpped it back so it wouldn't stick me. After it was secured onto the throttle arm it seemed to be hanging up and wouldn't move back and forth as normal. I soon discovered that the strand had detached at the pedal and had ggotten wound around the cable fouling the pedal action. So I withdrew the cable from the sheth rdetached it from the pedal. I didn'tt have a spare cable so tried to make do with whaat I had.
So I unwound the single strand without disturbing the other strands and clipped it off at the pedal. 1st pic is the single strand. Didn't think to photo it twisted. Thinking it wasn't very stable and subject to unwinding I soldered the end at the throttle arm. I got it back together again but had to remove the sheath and poke the cable back thru. I used solder flux to solder the cable but it was not really easy to get enough solder in without leaving blobs. I was able to to that eventual by sanding off some blobs.
Video shows throtttle cable.

I thought that the solder flux wasn't getting it so later I took a piece of cable and dipped the end in full strength muriatic acid for a second then with a soldering iron melted solder onto the caable end and it flowed right into the cable strands without leaving blobs.  I recall someone on a thread somewhere having difficuly finishing cable ends, FWIW

So I got the gasket (ordered 6-3 received 6/22 due backorder)  installed head, Gasket compressed without any problems. Checked compression at 117 117 115 and 122 and was happy about that. Then  fired it up. It didn't start very well and idled with no accel. Had to adjust richness quite a bit and  timing a little and started running pretty well I thought. Ran it to test acceleration and was happy it came close to matching spec (time to 10 mph increments).  1st pic is screen shot of  excel sheet with accel data. Fell off a lttle at the top end but was a helluva lot better than B4Valve job.
Engine runs 100% better and sounds better too. Starts cold with a shade of choke; no stumnbling as before. It's seat of the pants tuned so maybe needs a little more tweaking but satisfied now.
Video where I got the accel data from (speedo).

Really the first time I've driven  the mini and it is a fun car to drive. Couldn't help but compare it with the 50 60's cars I learned on. The handling is so much better than the 60s tanks and boats.

Wow, that ran really well! Is straight up on the speedo 50 mph?

No straight up is 45. 50 is the mark to the right. Video is little difficult to see. Yeah compression improvement and Pertronix was good medicine. Pertronix was definitely a better spark. It actually does 70 in 39 sec where the spec is 44. Not bad for a tractor engine.

Yeah I'm beginning to trust it now. Earlier I didn't trust it further than I could throw it. Longer trips may be a possibility.

Yeah, short trips are the order of the day for the first 500 miles. Once you get there, change the oil and filter, retorque the head and set the valve clearances and if you've had no issues - go for it!
