Right... covers off, engine cranked to put the cams in the right positions, and the feeler gauge felt its way around. So, again, some queries for the more experienced among us:
My inlet clearances appear to be nicely within tollerance. The 0.10mm gauge slips in with a hint of tightness, getting tighter on the way to 0.20mm.
The exhaust outlet is a bit different. These were tight. I'd say that the front and rear were about 0.18mm, below the 0.20-0.30mm range. This strikes me as rather odd.... that an engine with over 20,000 miles on it should be this tight. Perhaps it's something that will wear with more time and miles?
The engine certainly was cold, and has been started only once in the past 3 months, last week. I'm guessing that my measurements indicate a machine that's still relatively un-worn, and that with time the exhaust clearance will increase.
No, really I'm just looking for reasons *not* to adjust this
Comments please, TIA.
