I agree, you'll have to move the timing belt one tooth on the injection pump sprocket so you can advance the timing farther.
That's probably why it stumbles after a cold start.
Having the pump tilted farther forward also makes it easier to mess with the injectors.
Then just watch those clear lines before and during startup.

I’ll try the timing bump. Another thing is I know the fuel in it is probably decently old, which probably doesn’t help, but it does have a new fuel filter. Every once in a while I see some tiny air bubble go out the return line, and after it sits a bubble sits at the top on the line to the pump. It has an electric fuel pump which probably helps a bit but I still think there’s an air leak somewhere for sure. The pump has all new seal so I’m almost sure that’s not what’s sucking air.

Reset the timing tonight. I advanced it by one tooth as recommended and then started it and slightly adjusted by ear, and holy smokes does it run nice. It has great power (for an NA) and purrs nicely at idle. It is quite a bit louder with the timing more advanced, but that doesn’t really bother me. Thanks everyone for the advice!

A bubble sitting by the filter is common.
If it was sitting at the outlet of the pump or came from the input of the pump instead of the filter then it might be a mainshaft seal.
A little dip in the line between the pump and filter will let you know where it's coming from.
Glad to hear you got it running so well.

Just out of curiosity, is it worth it to rebuild a 1.5? This one runs pretty well as I said, but after putting some miles on it I see the head gasket is leaking some oil externally. There is not much blow by at all, so I think the cylinders are probably decent. I’m thinking with ARP headstuds it would be pretty good. Thoughts? If I do decide to rebuild it I would prefer to run with a turbo.

I know that the issue could be fixed by a simple head gasket replacement, but I’m itching to build a motor from the ground up!

If you build a 1.5 you'll need a turbo.
It just doesn't have enough power to handle a hill and a headwind.

I have everything to turbo it so that’s not a problem. With head studs and an oil cooler would it be plenty solid? I’ll also use a 5 speed transmission rather than the 4 speed. I don’t want to rebuild a motor that’s not going to be reliable or be able to takes hills.

Well, then go out and find a 1.6 and put an end to the drama already. Yes....it really is that simple.

In Montana it’s not as simple as just finding a 1.6.... They are difficult to find and outrageously priced when you do. This is the first 1.5 I’ve had, and I’ve never rebuilt one, so I don’t know if it’s going to be reliable if I rebuild it. Some people claim that 1.5s are piles no matter what while others say they are like 6.0 powerstrokes, with headstuds they are fine. No need to get upset, and I’m not really sure what you mean by drama, just asking questions from people who I know have more experience with these cars than I do.

My 1.5 with VNT-15 turbo worked great and took some serious abuse.
It'll work great with a turbo,... if the headstuds install properly,.. if they don't pull the threads out,... and I've only heard of studs doing that once.
