Carb conversion rough idle and misfire
Discussion
Okay so got a new “performance” non ballast coil on today. This allowed me to retard the timing down to 10~12° From the original “40°” at idle. The car runs much smoother now but still not perfect, rpm still hunts and sounds still slightly rough. A new fletcher su manifold arrived today and a 1 1/2 hs4 su coming soon. Hopefully this will fix my issues. Cheers guys for all the help.

Don't forget that such a drastic change of the timing could mean that an adjustment of the carb will be needed. Have a try at slowly screwing the mixture screw in or out, when warmed up. It will probably make a difference.
Cheers mate, got the colour tune onto the carb today and got it running perfectly, but the Nikki carb has now sold ![smile](/inc/images/smile.gif)
