hey guys
i got the new inernals in the vzr and starte dthe break in process at the track today. 2 tanks on the starter box, 2 more tanks on the starter box heat cycling up to about 70 degrees c

today i ran another 5 tanks at the track getting close to a race tune but its still rich now. peaked a temperature at 89 degrees.

the question now is that without the plug out i can turn the flywheel around freely. i guess its ready for race tune

should there be a nip at the top dead centre when i turn the flywheel ?
im new to these .21s
