Hi All,

I have just completed an engine rebuild.  This issue was caused by a crack in the T2 exhaust manifold that melted a coolant line and a fuel line, causing an engine fire.

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

Im trying to get the new engine running again.  Compression is great, spark is great and I have triple checked the timing.  I am getting some amount of fuel but no combustion. I have narrowed the problem down to a few possible issues.

  During the rebuild I replaced the 5ohm potentiometer that controls the mixture because the knob was broken off.  So I possibly mis-wired the replacement potentiometer, it is not actually compatible, or I damaged the board when I trimmed it to allow the new one to fit.  I wonder if anyone has one lying around I could borrow to test this link in the chain.

Thanks
