Have got my restored RT5 all together and did first start on it today with new rebuilt motor.
Motor is Bertils based, Motronic injection / ignition, flywheel crank trigger, cam driven fixed position dissy, fuel pressure at 40psi on regulator.
Starts no problem however the thing is running mega rich on start up / warm up cycle and does not lean out in any way at any temperature. (heavy black smoke, fuel pooling in intake, fouling plugs in seconds)
Have used the mixture dash pot in every position but it seems to make no significant difference to mixtures.
Does anyone have any experience with the Motronic control unit and can offer any input, details or setup info / specs, etc.
The only info I have is to start it on full rich (position 10) and lean out to position 6 on the dash pot when warmed up / ready to race.
My alternative is to replace with a current programable ECU but prefer to keep it original if I can.
Suggestions are welcomed.
