Dlb, I am very glad it was an easy solution as well. And I feel confident in knowing that I can properly set ignition timing & the carburetor mixture in the future, which is a big accomplishment for me. I'd consider myself reasonably mechanically inclined, but as someone younger than my Tercel i...

Thank you Nordical25, it is far from pristine but I try my best to take care of this T4. That’s a great point - I am satisfied that this is now a task I no longer fear or dread. In my eyes the most valuable thing you can “own” is your knowledge. I love to learn and I’m glad this is something I under...

Just thought of another thing that can affect timing that I have come across a few times -- remove the cap on the distributor and try twisting the rotor counterclockwise. It should twist a few mm, and snap back to its original position when you release it. If it doesn't, the grease that lubricates ...

https://i.imgur.com/DymV1rh.jpg After much frustration and further disassembly, I've got my Tercel back to good running order. Even better than before this recent issue, I'd say! I removed the radiator, valve cover and upper timing cover in order to properly inspect and set timing. After a bit of f...

Progress! I'm on the right track. It's still not running totally right yet but it's better. I learned a lot today using my timing light and vacuum gauge. I'm on the right track with the timing and carb adjustment but I still don't have it dialed in just right yet. Can't seem to get the timing advanc...

My vote would be a receiver mounted winch, as Petros suggests. With weight being the most significant factor for most choices on the T4, I believe the receiver mount style winch gives a good balance of low weight and adaptability. You could fabricate hitch receivers on both the front & rear bump...

Thanks Peter, I have the vacuum lines routed properly now; one from the Weber to the lower vacuum advance, and another from the manifold port to the upper vacuum advance. After reviewing the FSM more, as well as a couple different posts here on the forum, I realized how silly my original setup was. ...

Agreed. Timing is next on my list, then I'll look into the SCV stuff under the valve cover & double check the carb fuel mixture. The hesitation and backfire/sputtering that I am now experiencing started only recently. The improperly routed vacuum lines that I just replaced earlier today, those h...

Very interesting. To be honest, I don't remember seeing any apparatus like that next to the valves when I replaced my valve cover. Maybe a previous owner removed that stuff? It's worth looking under my valve cover again though so after I confirm proper ignition timing this is something else that I c...

I really would love to have the swirl control valve vacuum hooked up properly! I can try and do more homework but so far I haven't had success in locating documentation to assist me. I had just a smidge of time earlier today, so I replaced the old hodgepodge of vac lines with nice new lines, routed ...

Nordical25, The car is US-spec, & I do not have the high altitude system. Yesterday I was not aware of the 3 different vacuum advance units, but I now understand that my Tercel is equipped with the 2 port vacuum unit. This could entirely be different than what was standard on my Tercel; I am not...

dlb, I'm sorry, I tried to make my pictures & illustrations as clear as I could - yes, currently I have the single weber vac hose going to a tee, which connects to both advance ports on the distributor. It sounds like now is the perfect time to get some new vacuum hose and redo my routing. I'll ...

Thank you for the Weber tuning tips, Petros. That will be next on my list, after confirming proper ignition timing. NWMO, thanks for the description of the timing light hookup. I was going to check this task off my list today, however after referring to the FSM, I notice that my distributor's vacuum...

NWMO & rer233, Thank you both for chiming in. To touch on my previous comments, I confirmed there's no funny business with the electric choke. The power wire is making sound contact on both ends. Fuel pressure appears good with the new fuel pump still, although I have not tossed the OEM fuel pum...

While I was letting the car idle, I blipped the throttle to see if it would backfire like it did before, and I noticed a couple times the idle would shoot up after backfiring. This makes me think that for some reason my electric choke may not be operating properly? I guess I'll confirm that my power...
