Like the man says, too many factors to just pin one down. Start with the baics; compression check as well as leak down, static time, plug gap, etc. Look inside the dist and see if every thing is kosher, look for cracks everywhere (cap, etc). Clean with WD-40, lube your vac advance mech with a silicone lube. Make sure things are tight and loose when they should be. Check for vac leaks using carb cleaner or propane. Check the float on your carb, adjust the needles (1 1/2 tirns to start) and adjust the secondary opening screw. Measure the voltage on your coil. This is just the beginning.......Russ ______________________________________________________ Yahoo! for Good Donate to the Hurricane Katrina relief effort. http://store.yahoo.com/redcross-donate3/
