continued l-jet M20B23 troubles

That cannot be enough advance. Even air cooled engines run way more than that. Rev it up to 5k and see if it keeps advancing. That thing needs at least 30 degrees total mechanical advance.

I'll play with it, but the 19 degree spec was confirmed by a few different sources, and there's a very obvious mark on the damper..

Convert to fuel injected and electronic timing. Problem solved.

it's already fuel injected. converting to air injection soon.

19 degrees, there was a convenient mark on the harmonic dampener for it already.

What is the total mech advance ?

[Silverdogz]

ECU corrosion?

(continuing from http://www.r3vlimited.com/board/showthread.php?t=291366)

situation: very low power being produced by my l-jet M20B23; runs hot and overheats at high load.

diagnostics:
compression is good (~170ish all around)
timing belt is on right
timing is set to 19 degree mechanical advance at 3K rpm with vac advance disabled
mechanical advance works
vacuum advance works
plugs are new
injectors are freshly rebuilt
fuel pressure is in spec (2.5bar)
smoke tested extensively, no vacuum leaks
no obvious signs of oil and water mixing

any ideas on things I should check at this point? It feels like it's producing about 60 horsepower..
