My 87 'zuki is cutting out on the interstate, she just doesn't wanna run 65. It feels like a fuel problem. Are these Weber carbs legit? What kind of RPM's should I be running at on the interstate? Any ideas on what else could be causing this? It's somewhat of an intermitent problem. Thanks
Wow..I have a similar problem. Mine will run like a scalded cat (well as scalded a cat as a samurai can be) and then suddenly start bucking and coughing and not want to pull over 3500 (45-50mph) in 4th. I plan on changing the fuel filter but I really don't know what it could be, as internittent as it is
Check your fuel filter and fuel pressure. You could also have an obstruction in the lines. Try back blowing it back to the tank. if you cant do it with lung power somethings wrong. If all this checks out, check the float level.
Samiam, in your case, check you dist and bat cable grounds to the firewall. Clean tight and brite, is the rule, but also make sure the wires arn't failing. My dist ground got down to 4-5 strands and was intermitant as heck.
well, there is the carb extension piece that was a fix for a flat spot. Next time it happens, and your going straight, quickly shut off then turn back on your engine, see if it still does it(as long as its safe).
< Dumb question, where on the distributor does the ground wire come off? >
You should see a black wire with a snap-connector attached to one of the three bolts that holds your distributor on the head. The other side of the snap connector (both pieces are usually black colored) is fastened to the firewall with a bolt.
