Remeber thats is assuming that the motor is not coming in hot and idling high for that reason.

thanks

Or it could be the top too lean. As you come off power the crank is still full of the high end mixture and if its too lean it will idle high until it see the low end mixture. Try letting the engine idle for 10 secs then floor the throttle. If the engine take off clean the bottom end is OK and the top end lean, If its sluggish then fast the low end is rich and the top ok

Understood. I'll be sure to include this note as well.

If it is better, then do it again. Just make sure to check your glowplug after each run to make sure it is not getting dry. It should look shiny.

Thanks Uriah i will try that' btw what is the good temperature after the brake-in?
Thanks to you 2 dj' for the info'

I like for my glowplug temp to be under 300F on the +35. I usually run mine at or around 250-270F. I am using .8mm of total shims inside the engine. I am usiing Rocket Science 30%. C7TF plug. All of this can vary greatly with atmospheric conditions. Most important is to make sure your glowplug is not dry after you run. Temp guns vary widely on the temps that they give. Up to 50 degrees, or more sometimes. If my car is fast, and not slowing down, I run it. I do not care about engine temps. Sometimes they can be high even though you have plenty of lubrication. Especially on the Nova + engines. They create so much friction due to the tightness of the PS fit. Just look for some smoke coming out the exhaust
