With the type IV timing set right it's about 7.5 to 8* at idle. Has anyp0ne noticed a difference in temps if the timing is advanced at idle?
Reading the MM on the MS site, it say's, if you retard the timing at idle it will produce lower emissions by creating more heat due to the unburnt fuel left in the system. If retarding the timing makes things hot,can advancing it make things cooler or more stable, temp wise at idle? With MS it is possible to advance the timing at idle but still keep a 27* cap at the 3500 mark Keith |

Power has been proven with a 12* idle up to 28* full advance by 3000 rpm for most engine setups. With MS you can also pull our 3* or 4* after 4500 for smoother high RPM running.
If you tune for optimum efficiency your engine will run at its best in all respects. If you move away from those settings you are unbalancing the compromise. But you should pick up a CHT and test things out for yourself. (IMG:style_emoticons/default/wink.gif) |
