Cam Timing

[T-stone]

I want to play with my cam timing, seems to be off a little.

When i built the l28 i set the cam sprocket on number 2, it seemed to not want to idle right and spit out the carbs while under load.

i set the sprocket back to number 1, idle was much smoother and felt more reliable, it still spits through the carbs under load every now and again, mainly while cold and going up hill in high gear.

i have a mild cam, need a new timing chain and adjustable sprocket but dont have the money right now.

does any one know if i mite should adjust it differently, it seems as though something is just not right with it.

tdc on number one both valves closed exhaust is at 11 oclock and intake at 2 oclock

also i never did get new lash pads and rocker arms, how much could that affect proformance and timing?

To me, what you've experienced look like something different than cam sproket timing. I would start checking idle timing, sounds like you don't have enough advance at idle.

What about the notch inside the sproket, does it align with the one from the cam?

advance is already set a little high, and if its set any higher it will fight itself on top end.

i have the timing set decent, carbs are qualized and mixture set slight rich.

The only notch for the sprocket is on the clip that holds the cam in place, the v in the sprocket is alighned with the notch on the clip.
