Another 950mL put through the 90. I now have the MMM rear induction fitted. Seems to run smoother and for most part temps are even up to about 4200RPM then #2 gets hot, other are around 118C and #2 will get around 135C.
I'm still running 91 octane with Klotz KL-200 @15:1, needles are rich.
So far this engine has about 6 - 8 L through it.
I have also noticed that the main needle does bugger all. I can run it at full throttle ~ 6250RPM and wind the main needle out and it does not make top end rich at all and RPM stays the same. Winding the slow needle out does make it run rougher but overall top end RPM is about the same.
Obviously I am doing something wrong with this thing. .
