Of course its always better to run rich. Keeps the engine cooler & better lubricated. You can find a happy medium though... Too rich & you'll hydrolock, Too lean & you'll overheat the engine....
 
Run it on the rich side. I'm sure you know this, the motor will run a little leaner as it starts to run low on gas, so i always run it a tad richer (but racing my car doesn't sit more than 20 secs, so I'm not worried about staling if i can't get to it, thats the marshalls job ) :cheeky: ..
