Ron,

Howareya?

I'll give the flood-start technique a go. I seem to remember trying this but luckily its always happened when I've either been able to just jump in the Mazda or didn't need to be anywhere immediately. So I'll try to verify flooding this way.

George's suggestion regarding starter speed may be contributing. I've always thought that it turned over slow compared to other cars but just attributed it to an old Volvo quirk. The battery is new.

The thing that is selling me on the colortune is that it seems that it would give a fairly accurate indication of jet position in each carb.

The formula that I am leaning towards with tuning is Unisyn for carb balance, colortune for jet position, and exhaust analyzer for what the needle/carb oil/spring is doing for me. This with properly adjusted valves, timing, and compression and leak-down tests.

Am I missing any important/easy/obvious tests I can do without a dyno. Road testing is the proof but I'm pretty green so I don't really know what a properly tuned 122 should feel like.

It runs OK, but the Mazda still feels smoother and faster. Its an '87 B2000 so not exactly a feather in the Volvo's cap but still early in the tuning process. I just picked up a B20B with an extra F head to rebuild so better things are in the future.

Its not too broke so I'm not planning on getting into it until the weekend in any case.
