A bit wierd this.... Trying to get the Chevy running properly. Its always been way too rich & very sluggish. If you floor it quickly from standstill it back fires through the carburettor.
First step was to set the timing properly using a strobe. I painted the grooved timing point on the harmonic balancer white (with a piece of black insulation tape either side of it so it is easily detected), hooked the strobe up to No.1 plug and...... it doesn't pick up the white timing mark! No matter how far I move the distributor its as though the timing mark is in the wrong place.
Any ideas? This ones got me completely stumped.
