Idk what’s different on the 85 m46


Either way I still need to figure out what’s what inside

I think they had 3.73s also, will look it up but also @pinguin what’s the diff ratio on that 242 you got?

Something doesn’t add up in my equation, I seem to recall that the 242 Speedo was reading fine

This is good help. I know what to check

I dunno, it's parked in a friend's garage in Minneapolis.

That's an M47. M45 & M47 use the same gears as AW70/71. M46 gears are different

You can't trust those online catalogs.

@Jack I followed the same procedure re: control valve and also found mine was catching in places as well. After polishing with fine steel wool and thoroughly spraying with carb cleaner it is working well. Still a slight hesitation with revs dropping but much improved also did terminal 11 mod and running 15psi @ 11.6 afr. Thanks for being the guinea pig!

very good

I checked base fuel pressure. This shows it was set too high, should be nothing coming out. I adjusted it

Took it for a test drive and still had some high/sticking idle issues, swapped over to a different IAC and it's way better now. Not sure if original was intermittently bad or my base idle is off but I will check it all again (hopefully) tomorrow

I need to really work on the paint, Maguire wax is streaking, indicating (I think) bunch of dead paint..

 

[Jack]

been a while because I have been struggling to get it to run right ... but after using the "right" tool I think it's finally ready for smog

1982 cis b21F high Co

So I been trying to figure this car out for a while now....
I recently took it to a smog tech and he said the CO was at 10%. @spock345 let me use his CO meter and I got it to 4% at idle and about 2-3% at 2500rpm

If I lean it out the CO adjustment at the fuel distributor the car wont start

updated engine harness, updated ignition harness
new bosch cap, rotor and plugs
new bugicord wires
new fuel filter
just about everything has been refreshed on this engine, gaskets, timing etc

throttle switch is adjusted properly
coolant temp sensor is within spec

this...

I buffed the paint few weeks ago and it's looking much better. I need to take some photos of it.

Today I replaced the roofline trim. You use the old bottle opener keychain to remove these. I fixed the dome light, the door switches were corroded. Adjusted hood and door hinges.

Took it for a drive around town

it PASSED bois!
looks like the cat could use some love but this was also measured after it sat without being driven.

Congrats! Quite a saga

Nice post office you've got there.

One Grand Blitz Wax is the deal. Give it a try. It's the nicest paste wax I've ever used.

I don't know Ja boi? RE license plate

Love the progress and looks incredible, hope it serves her well!!

 

[Jack]

idk maybe I didnt replace the RMS but in either way Im going to replace it now...

Today I pulled the transmission with gfs help

everything looked slightly oily and when I pulled of the housing it seal felt old and crusty

WTF Im pretty sure this was new too

I got a gasket set for the trans and OD in order to make the speedo work properly

 

[Jack]

There's only 1 black M46 speedo gear. It works for both 3.91 and 3.31 rear end gears. The difference is the metal gear in the overdrive. For 3.31 the metal gear has 7 teeth and for 3.91 it has 6 teeth. Look at the housing near the output flange. There should be a 6 or 7 stamped into the housing to indicate which gear was installed.

Turns out it's a 7

Thankfully I got one with a 6

Thank you! Most stressful part was not having a way to test it prior to smog

Daughter says "I dont know Jack"

She loves the car, other week she drove to Sacramento and back in one evening (I was there) and only stalled it once. Still few bugs to work out, see above but it's so close to being done

Nice post office you've got there.

built in the 30s, it's historic https://livingnewdeal.org/sites/post-office-oroville-ca/ but the info in that links sucks

 

[Jack]

today.

big decision with RMS!

New hardware. Im wondering if I pushed it in too far ...

took the trans apart

 

[Jack]

difference between #6 and #7.... They dont want you to mix up the 7

replaced the housing with the correct marking also

turns out I made this socket years ago

It never fails that I install the small/big gaskets the opposite way at first but I got it right eventually. Cast steel "drum" is also powder coated.
