Ok I will report back. Also, no I did not replace injectors. Maybe this has something to do with it? The old injectors I'm sure don't emit as fine of a spray as they should and maybe all the fuel doesn't get burned as a result.
It has less to do with the spray pattern and more the pop pressure and popping consistantly.
Unlike a DI motor, the IDI has the fuel spraying against the pre-cup, which should vaporize it pretty well(at least with the engine warmed up).
This is why you can get good power and efficiency out of R&D's Stage 1 injectors which basically just have the nozzle reamed out(which hurts the spray pattern, but helps overall flow).
In a DI motor, doing that would melt the pistons due to hot spots.
Pop pressure, though... even slight differences will change cylinder-to-cylinder timing. It's entirely possible to have an engine where 7 cylinders are "correctly timed" and 1 is "retarded" and causing all of the smoke, with a worn set of injectors.
Also, if you *do* replace the injectors, make sure to get them from a reputable source. Mel would probably be your best bet as you have his IP, though Russ(Typ4) and R&D are also reliable.
Part of the key to good injectors is new nozzles - just re-calibrating(shimming) a worn injector won't really fix the problem for long.
Quite possible. It's really recommended to replace injectors and ip at the same time, fresh injectors make a big difference
^^ Very much so.
Here's a hot start. Completely different sound than my heat soaked IP. This sounds like it's hitting but sometimes just won't and there's smoke at the tail pipe always. Before there was no smoke until it hit.
Timing sounds a bit advanced. I'm hearing "knocking" when it's trying to start, sounds very much to me like when you try to start an engine with ether(because it's detonating early).
If the engine was cold, how it sounds with it /running/ would be normal to me, but hot? It should quiet down a little.
Retard the timing a little and see how she does.
edit again:
Also, your smoke with the revs? Too much fuel. You are overfueling it because the screw is turned up too high. You go up a steep grade like this and you'll be spewing a cloud of black smoke behind you, unless you are /very/ light on the throttle.
