4 runs so far today without a hitch... Like clockwork compared to the runs 3 wks ago:

11.65
11.58
11.62
11.56

diff between fast and slow is cold trans hot trans

engine builder tried to get me intouch with friend with "bore scope" little camera but he had already left for the day. If I can get one $150 I'll go ahead and pick one up. Will be handy....

I'm taking my chances this wkend and my luck is holding up so far. Fact it was brass not steel probably helps
