Quick question. I have a PTM 5 port that I had Brian do a bench break on and I have 3/4 a gallon on myself. When do or can I stop pre-heating the mill before I start it. Mind you I tak "SUPER GOOD" care of my stuff and want the most longevity out of it. Now it is in a truggy with a 8mm restrictor in it and soon it is going to a buggy, when I go to the buggy what restrictor do you recommend? what is the smallest made? And who makes it? Because this 8mm one in my truggy is actually too much right now on my local track which is kinda technical.
