make sure u dont have a rotor/ cap phasing issue, that will cause a misfire.
with 88's in a 600 carb, u must not be running a pv?
a shot in the dark would be plugging the pcv off and running a breather.

Go Knock about 6* out of the timing and test drive it..... See if that makes it better?

will do...

Look at burn marks on cap terminals, see if they are off to one side and carbon trailing inside between terminals.
You can dill holes on top of cap to see if the rotor lines up at spark a well, with time light.


u have 88's in secondaries?

ok i will check the cap... thinking back when i did the springs im thinking they were centered but will look again...

right now for the street the carb is set up with 66 primaries with a 6.5PV/ 75 secondaries... @ the track i go up to a 69/75

what cam spec and what exh flow ratio on the heads?

u say its shooting ducks at the top?

how do the plugs look?
what heat range?
Click to expand...

cam is 246 @ .050/ .475 lift single pattern 106LSA installed at 102

hvn't checked the plugs since i pulled them to do valve springs... they looked fine then, a little dark but i had been street driving with my race jets in it as i was trying to determine if it had gone away...

to be honest i dont know what the heat range is on the autolite 65's... but all the plugs look the same, maybe a tick cleaner on the center two...
 
lean on top end
fuel supply issues
air leak
reset flote level
clean out carb.crap inside
worn carb throttle shafts

points gap or dist issue

comp test

low volt to coil
bad wire coil/dist
bad fuel

generally it's just lean

fuel supply issues
air leak - none
reset flote level - did
clean out carb.crap inside
worn carb throttle shafts

points gap or dist issue- regapped before install

comp test - havn't done one in a while but when i was doing springs i had less than 2% leak down on every cylinder even though it hadn't ran in about two or three weeks...

low volt to coil - thru MSD box
bad wire coil/dist
bad fuel - 100 octane leaded race gas

generally it's just lean

start up @ night with hood open and no lights
look for spark loss/cross fire something
have someone there who knows cars and is objectible

why is it lean.. fuel pressure guage @ higfh end read?

install new points

install new borrowed working carb.

if not lean...advance the **** out of timing
work backwards

Yeah geez, are you runnin a points distributor? How are you setting dwell? A feeler gauge? Use a dwell meter.
