i use the 6.5 insert and power masters fuel in a serpent. is this fuel any good?

do a little test....fire your engine up on the starter box, get it to a steady idle, then spray nitro spray right behind the flywheel...just a little spritz....see if the engine stalls or not.........

Just a quickie really,

Running a nova plus 4 btt in a MP9, using a 9901 pipe and 41021 header with a c6tg plug jvd clutch and 13t bell.

My endpoints are set and the carb doesnt fully open 6.5m venturi running 25% fuel.

Now my query, I have the idle gap set a 0.6m so thats good.

At the weekend is was hot and my engine wouldn't settle nicely on a idle no matter what i did went rich LSN then Leaner LSN no change richened out the top and repeated etc...

It ran but wasn't purring, also after 7.5mins i was on vapour! Now the engine is around 22 tanks old now. Always preheat before starting too.

I tried the base settings that i got off here and that was way too lean was running on just on the box so just some points to clarify -

Base settings for the engine?

what sort of tune are people putting on these I'm not an expert at tuning but I've got a rough idea which is why sunday was so strange?

my HSN is 3.75 out

LSN is 5 1/2 out..
