Misfiring and sluggish acceleration when exiting traffic jam

Recommended Posts

Just installed a coolant reservoir tank to my champion 3 row radiator. It´s working better now. Anyway, the car is still presenting some sluggish acceleration after getting  stuck on a 5 to 10 mins short traffic. Can someone explain to me why if i pull out all the NGK BP6ES spark plugs and brush the carbón off, the car accelerates fine? I have both of my carbs set to 3 turns clockwise. If i lower it more, i start loosing power at 1st gear.

 Yeah, clean them again. You've already discovered how it will run with fouled plugs. New plugs would be better.

Left to right in the following order 6-5-4-3-2-1. I pulled them out yesterday after the long idle on saturday evening traffic. I even noticed that the spark plug gap was reduced from .031 to .028. Is this normal? Too much heat is causing this???

Get some new plugs, gap them, while you have the old ones out do a compression check, write down the results for each cylinder, put the new ones in drive it for a week, take pictures of plugs and post.

 

FI or Carbs?

 Good advice. I'm surprised at the color variation in the plugs. Especially #5 and #4 since #6, #5, & #4 all run off the rear carb. @jalexquijano Is there always that much difference in #5 & #4 plugs?
