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 |

I am planning on using the stock 8:1 compression pistionsfrom a EA case motor.
I have 7:1's in it now. Going to 8:1 will probably not raise the temps. much. I'm just looking for a bit more perf. but want to keep a reliable DD in a 1.7. Keith |
