Transmission or Engine ?

[mrdoiron]

Have you checked to make sure the intake isn't obstructed? Sometimes the flexible air intake hose delaminates on the inside, blocking airflow to the engine above idle.

I hadn't noticed anything obvious.
I dropped it to the Transmission shop to have then verify their work - and reverse the shaft 180 while at it, I'll post any findings ...

Is there a chance that the float is stuck on, the choke is not on, but wonder is internally that can happen, and if it is an easy fix of not

thx

I just remembered something else.....my first car/truck was a 1977 International Scout II that I got from a neighbor for $700. Anyways I drove it for a couple of years until the rust got the better of it. The relevant part is that for a long time if I had the hubs locked in and the 4wd engaged in high range (it was an automatic with hi/low 4wd) the truck didn't want to go any faster than about 25 or 30 mph. One day while driving home in the snow I had to use 4wd to get back up the mountain roads that we lived on. I was chugging along at 25 mph in high range feeling oh so restricted when there was a loud bang. After that the high range 4wd worked great and the truck would go as fast as you wanted to go in 4wd...and I know the 4wd was still working. Something was bound up and I am not sure what. For all I know there was years of driving train binding going on and something finally popped. I never figured it out but assumed that something was tight and luckily broke free...instead of just breaking.

Interesting angle, I wouldn't have thought to look in that direction - except for having the rear drive shaft flipped 180as they installed it reverse - but didn't really assume that to be a contributor to restricted power.

thanks -

Make sure the choke isn't stuck on.

Pull the plugs and post a close picture of them. This is sounding more like a mixture/ignition problem now. In the meantime do the usuals like check the timing and point gap.

Forgot to post what the culprit was... appears the ding dongs at the trans shop got the new points on wrong, and likely caused a backfire or sorts blowing out between #2 and 3 :

Fixed at their expense, i hope

I don't know if I would agree that a backfire could blow the HG. It's designed to contain combustion, whether it happens as scheduled or not. Furthermore, that looks like it was blown for a long while. It takes more than a few miles to erode that much gasket material. The HG on my MGA blew probably before or shortly after I got it 20-some years ago. I rebuilt it last year and discovered the problem. The burned antifreeze muck actually resealed it and although it was underpowered, it never smoked or lost antifreeze during those decades. Is it possible something similar happened to you? Perhaps on the test drive after the shop did the gearbox service, a worker gave your Landy the beans and dislodged a similar sealing chunk and made the blown HG more apparent?

I've just never seen one go from presumably OK to that bad in such a short period. The good news is, unless the head and/or block are flame cut, a new HG will sort it.

Put me on the "I doubt the transmission shop had much to do with this" list.

Also, put me on the "wouldn't have a transmission shop mess with my points" list.

I know, I know... I had my doubts about having them do anything other than reseal the trans, but since they were at it and I needed the rear shaft replaced they did that.. which they put on in reverse. So you get into that mode of how far down the rabbit hole do you go, and had them reverse that at their cost. And since they were working it I had new points set sitting on the front seat, and they ask if I needed that put on for me. So well into the rabbit hole I said ok, and they called and said they heard a very loud "bang" / backfire... then I went and got it - and then had power loss problem.

So could be coincidence - but they didn't charge me anything for the work they did, and I had North Texas Rovers fix it.

lesson #78 learned...
