Update:
first thanks to all reponses, love this little community
EPU connected:
Start normal, hear the fuel pump running, hear the clutch engage, the starter
spins,
we hear the "secondary boost of amps" and everything spins much quicker, the plugs
spark with the same intensity and frequency of our other L29 (so I don't
think its the plugs anymore),
EGTS arc up to 600, fall back to 575 then 550 as she stays at 20%.
We then shut her all down. Went out, and hit air start without fuel etc, so we
could hear the sparking, she sparks exactly like the other one we have (she starts
fine)
I'm thinking start control box now.

Not trying to be condescending, just throwing things out there.
The start control box controls the start sequence. So if it is doing all 3 steps,
what could the box not be doing? After 19 seconds the sequence is stopped by
the start box. (4th step)
The ignitors work. Otherwise there would be no light off. If only one ignites,
it would result in a HOT start.
It sounds like fuel flow. If the engine starts, EGT rises, RPM increases, it can
only be fuel. (It could be air flow if it were an air starter. (Or the intake/exhaust
covers where still installed) Just Kidding!
As I mentioned before, if the fuel filter was changed, did you bleed the fuel line?
Is the Fire Cock open completely?
During start, do you push the fuel shut off full forward?
When it is at 20%, have you tried pushing the throttle up a little?
Has this airplane flown before or is this a new project?

Fuel nozzle issue or main fuel pump pressure? Also spitballing.

Thanks so much Bill.
1. Not a project, shes been flying quite a bit
2. Last week, normal start but stayed at 20% for almost the whole 60 secs, then
she kicked up and went to normal rpm and egts.
3. A couple of days later weve been experiencing thisnissue.
4. Today swapped igniters. No joy.
5. Fuel is leaking after the start attempt. (In the can the. Out thebtail, we
have nice white thick exhaust during the attempt.
6 stays at 20% with reducing Egts, then I shut down.
All plugs and covers removed. ;)
Firecock fully open.
No fuel system service
Fuel pressure is at 8kgs per cm2 during this sequence.
