Re: [ihc] Intake manifolds

I set mine at 15 deg BTDC and run premiun gas.  Amazing difference in the character of the engine.

Ed,

Guessing

I think you should check your fuel pumps pressure and volume.

Replace the fuel filter unless you've already done that.

Check the plug wires for even ohm/inch even if the wires look OK. 
That's a hot coil.

Try the timing at about 12 degrees early. It works for some, but not for me.
