Posted Sun Mar 20, 2011, 7:11am Subject: VIbiemme Super some shots coming out too cold,
Hi All, I installed a group head thermometer a couple weeks ago and i try to make 200 degree shots, however it appears like only about half of them are coming out at 200, other half of them come out 197 to 198, it keeps them very stable through the shot, but they are colder, i do the same warming flush every time, about 4 seconds of purging, this morning i made 2 shots, first one came out 200.5 and approx 2 minutes later i made another one that came out at 197 degrees, i used exactly the same warming flush on both shots, anybody know whats going on? group head is consistently at 193 during idle when i turn on the thermometer
