Hi all, this is my first attempt at posting on the notice board so please bear with me.

I only kart for fun, and over the years have gained a number of old Parilla TT27 engines and hoped someone out their might be able to help with a couple of queries.

Question 1)
I generally run NGK Plugs, heat grade 10 or 9 (dependent on weather conditions) but I�m not sure if I should be running a basic B10EG or BR10EG (where the �R� denotes a resistor plug). I�ve read the �Maintaining 100cc Kart Engines book� by Philippe Evrard several times, and in there he refers to �Not using Resistor Plug Caps� as they cause a reduction in spark intensity, however is this also true of resistor plugs?

Question 2)
A number of my cylinders are looking a little glazed and I�ve been considering purchasing a flexi-hone to remove the glaze and improve oil retention. I�m satisfied with the actual bore diameters etc, as I�m only using the engines for fun and not searching for ultimate performance. My question however is what grit value hone should I use? A lot of general automotive applications use 120 grit, but this seems a little cause for a kart engine.

Also just out of interest, should you use a different grit value for Nikasil plated cylinders?

Many thanks,

Keith
