Hi All,

=C2=A0=

I have just completed an engine rebu= ild.=C2=A0 This issue=C2=A0was caused by a crack in the T2 exhaust manifold= that melted a coolant line and a fuel line, causing an engine fire.=

=C2=A0

I landed safely and had to rebuild the en= gine because the o-rings melted from the coolant loss.

=C2=A0

Im trying to get the new engine running again.=C2=A0 Compres= sion is great, spark is great and I have triple=C2=A0checked the timing.=C2= =A0 I am getting some amount of fuel but no combustion.=C2=A0 I have narrow= ed the problem down to a few possible issues.

=C2=A0 During the rebuild I replaced the 5ohm potentiometer that contr= ols the mixture because the knob was broken off.=C2=A0 So I possibly mis-wi= red the replacement potentiometer, it is not actually compatible, or I dama= ged the board when I trimmed it to allow the new one to fit.=C2=A0 I wonder= if anyone has one lying around I could borrow to test this link in the cha= in.
