102,000 miles. New plugs and wires. Timing is at 2 degree's otdc as factory should be according to autozones site. Carb is rebuild and runs great. Motor shakes a good half a inch when warm and idling.when at about 1000 rpm it idles smoooooth. There is no vacumm leaks. It takes me 15 seconds to get to 60 at full throttle...is that about right for a 318 in a 78 d150 with the 2 barrel factory?

 

BTDC and ATDC are familiar to me but what is otdc?

 

oops my bad,i mean btdc. truck drives great,i drive it to work and around city everyday,just seems to be low on power sometimes and runs somewhat rough. could it just be low gears? i have the 8 1/4 rear end.

 

What does the emissions control label under the hood say for timing?

 

sadly no stickers anywhere.

 

Mine is an 87, 318 My timing is supposed to be at 8 btdc. I usually keep it around 10 for the little extra power. IMHO, you're timing is retarded.
