'86 AL21 3ac vacuum advance went...

[overs10ded]

Finally recieved my Weber32/36! Here is what the jetting is; main 140 for both, air 160,170, idle 50 both, emulsion tubes F50, pump 50. I have to start with these jets. I do need to get past the emissions part of our inspection here which the car failed w/500 HC and only needs 450HC or lower to pass but with retarding the advanced timing will do that trick I'm pretty sure this next week and I'll be swapping carbs probably Tuesday. The Weber has brass floats...haven't googled yet but the redline kit only has plastic float settings...are they the same?

[dlb]

no, they are different for the plastic and brass floats. they should be set correctly out of the box so you don't have to mess with them but here are the specs if you want to check.

Welcome to the Club!
Autozone has a great resource for our cars; many times it mirrors the FSM, but frequently it has details missing in the Toy manual - and - it has many real photos! A link to the 2WD shifter is here (scroll down a tad): http://www.autozone.com/autozone/repair ... 52800522d2 Then do some exploring on some of its other topics in the Repair Guuide. It covers Tercels from '84 to '94, so some is irrelevant to our AL21/AL25 dcars - but it is quite handy as well. You can join it on your own, and plug in other cars for similar Repair guides.

At one time we had at least 4 other members who lived in Costa Rica. Do a search here using just "Costa" and you can peruse their posts - not many, but they may have some sourcing info in their posts.

Thanks a million dlb and Tom! I had the shifter apart and tightened things up nicely however need some replacement washers as some were missing and have caused things to loosen up again-sloppy shifter syndrome! That Autozone resource is fantastic!!! Plus I see they give you cash back incentives too.

dlb, I appreciate the float setting diagram very much! Also do you think I should start out with the 170 air jet in the primaries or the 160? That is my only option at this point. I'll start ordering more jets once I get an indication in which direction I need to go. Any jetting help for Webers in the 2,000-3,000 foot elevations is welcome.

Also have recieved a vacuum guage, oil pressure guage, and the correct vacuum advance so that I can retain the altitude compensation system. Still want a tachometer! Fun projects this up-coming week! Baking and farmers markets for the next 3 days though, so Sunday is my day off to start some projects! Although I'm working on the Weber now...adjusting the float, putting a kit in, ect.
Once again, thanks for your help!!

Good times!

Your jettings should work ok for your elevation and climate, assuming Costa Rica is 90* right now. You might go with bigger jets in the winter if the temp gets 30* + cooler. Here are my jets that work just great at 500 elevation and 95* :

mains: primary 125
secondary 140
air: pri 160
sec 170
idle: pri 42
sec 50

I don't know my emulsion or pump jets, I just use whatever it came with. Driveability is good except when the choke doesn't seem to work occassionally on cold starts, not sure why. Once warm it runs great. When I had bigger jets I rigged a voltmeter to the O2 sensor to determine the mixture. It indicated too rich (close to 1 volt, should be about .5V). Not sure how accurate this method is, and I haven't checked it since slapping in the smaller jets.

Thanks danzo! Actually the temps where I live in Costa Rica range between 65-83F all year long. Got to say for me the climate is perfect. I'm sure I'll have to tune but hoped to be close enough to be fairly driveable with what is in the Weber.

Good times!

Still want a tachometer!

bruce, i'm not positive but i am confident that the gauge cluster from the SR5 4wd tercels will plug in without mods to the 2wd. it has a tach and would look stock in your wagon. if you can't find one there, someone here could mail one to you. they're quite common. the 83/84 SR5 gauge clusters only go to 110 mph while the 85-88s go to 180 mph (or thereabout), and the canadian ones are in kms rather than miles.

[overs10ded]

Yes dlb, that is what I would like to do is install the SR5 cluster, if I can find one. My '86 is a 110mph. What year did the dash style change? What years exactly will interchange with the '86? I don't know what the extent of R&R'ing the gauge cluster is but I do need to do a heater core eventually (not as necessary here as in BC but still need it in CR!) and that would probably be a good time to just do it all! Thanks for the input on that idea!

Good times!

swapping gauge clusters is easy, only takes a few minutes. i posted a guide for installing an inclinometer which involves removing the cluster so you can follow steps/photos 5-8 of that. here's the link:

sorry, i was confused between the kph and mph speedos. looking it up, it looks like the 83/84s max out at 80 mph and the 85-88s max out at 110. i think the kilometers/miles thing mixed me up. i like the older ones because it looks cooler when you can get the needle closer to its max speed.

there's a guide for replacing the heater core here:

Wow! The gauge cluster looks great and easy! I could do that and still save the heater core for...um...some other time when I have LOTS of time! Appreciate your help once again dlb!

Good times!

Installed the weber....delete everything and do the PCV to EGR conversion. Things are going good. The jetting must be a bit lean...I have a slight stumble right off idle...using 160 air corrector with the 140 main w/ 60 idle. Swapped the 170 that was in the secondary and made it worse so I've got some jets in the mail; a 65 idle primary, 60 secondary, 150 and 180 air correctors, and a 145 main! first 2 refuelings netted 25, 24.5 mpg...up 2mpg from the Aisian carb! And the engine bay is much cleaner without ANY of the emissions including the EGR. Passed emmisions easily without a problem!

Also not using a regulator yet.

bruce, i think everyone has found that the weber does slightly stumble on hard acceleration from idle. i know that hooking up the two vacuum advance lines helped correct this on my terc, but it was never perfect. i believe it's the nature of a mismatched carb and engine. forum member glet71 now owns that terc so he might be better able to describe exactly how it runs.

also, getting the vac advance hooked up correctly will also improve the mileage. i was getting an average of 26 mpg and as soon as i got the vac advance sorted out and sold it, glet71 started getting over 30 mpg. big difference, especially on highway driving.

[overs10ded]

Hey thanks dlb! Now I only have the vacuum advance hooked up from the forward most facing port or right port as one is looking at the carb from the riders side fender (right fender) and using the outer most nipple on the advance. The straight one. You actually listed the appropriate points for vacuum line hookups earlier in this thread and thanks for that too! Have a great day dlb!!!

Good times!

Update for mileage with the Weber; 26.5 mpg on a 300 mile tank of under 55mph driving and mostly city and curvy, hilly country roads. The fun kind. Still waiting for jets that are "in the mail"! Hope to find 30mpg!! Very happy with the 26.5 and all performance over the aisian aside from the cold start, althought without a choke hooked up! It's a DGEV w/water choke and I haven't hooked it up yet, need more heater hose!! All at once when I get the jets!! Hooked up the vacuum advance with the Weber's ported and ventury vacuum ports which might have helped on mileage. Also installing a vacuum gauge now. Mechanical oil pressure as well. Is that the oil sender on the left side front (as if you were in the driver's seat)? Guess I need to look in the manual. Running 5-40 Quakerstate synthetic. Burning 1 qt to 750-800 miles! I'm happy...just hope the chattering clutch will hold up until DEC along with an inner cv bearing. Right side. Getting a little wobbly!

Good times!

Bruce

[dlb]

yes, that is the oil pressure sender right by the oil filter. i actually messed around with oil pressure senders and adapters for mechanical OP gauges recently. the thread for the OP sender is a funny one. i covered it in this thread:
