Desperation

Well heres how things stand. On saturday Dave sat out with me in the rain.

First he pulled the bowls and re-jetted it from a 70 - 78 down to a 68 - 76. It cleaned up the eye watering exhaust a good bit.

Next re-checked timing. My first mistake was ASSUMEING that when I set my initial of 18deg the distributor would be good for its all in of 34 deg at 2800rpm. Not so I was lacking. So setting it at 2800rpm to get my full 34deg leaves me with now 23deg initial but it still starts ok so no worries. Dave set it up but it needed a touch more so the initial set up as tested still produced a bog but not as bad. I have yet to drive with the 4 deg of extra timing.

Consensus is looking like the 650 speed demon with mech. Secondaries DP may be too much for my motor.

Stall is a 2800rpm with 3.55 gears.

Playing with the car on the way home loading it up to 2000rpm and launching still creates a bog and wont even squeel a tire. The only way I ever killed the bog was disconnecting the secondaries.

I still need to try and re-set my valves to try and get rid of my lifter clatter when hot....
