Truck ran pretty darn good today. Much of the bottom end power has returned thru leaning out the mixture. 70 mph is easily within the capabilities of the engine and its fuel/ignition set up. Once this is done, I can tweak the cold idle and choke and it'll be done...though given the potential of this carb/ignition I have a real hankerin to mill the top of a spare intake and direct mount the carb over a bigger hole, eliminating the restrictive adapter....but I don't have a manifold! So....on to the timeing adjustment.

Tonights job is to leave the carb idle/mixture alone and move the advance up to the recommended 18 degrees BTDC.

But since I'm at 15 degrees BTDC and off my 12 degree timeing tab, I'll have to double the accurate readability of the existing timeing tab....no timeing tape and no measurements and I'll still have an accurate read out in one degree increments up thru 24 degrees. Stand by and I'll photo it up and advance the timeing to 18 degrees BTDC for tomorrows test run.

Sharps, you mean like this:



I had it on my turbo'd inliner. It is roughly 2 1/2 times the surface area. It did good. I JB welded the voids and after a year of hard driving, it looked like the day I filled it.
