Don't think it's something that'll happen much before summer. Gonna have to start slowing down on the spending. -- Conor I'm really a nice guy. If I had friends, they would tell you.

The linear movement of the piston is relatively small at TDC in relation to the rotary movement of the c/shaft. A degree or two either side of TDC makes very little difference to the DTI reading,.making it quite difficult to establish the 'exact' highest point of the piston. Physically stopping the piston when it's maybe 10-15 degrees either side of TDC, means an accurate mark can be made on the pulley both sides of TDC, which, if done with care, means that the point exactly between the two marks is true TDC.

They wont be picked at random, from a box of springs. They'll be springs designed with a specific rating to give the compression movement and strength required, so checking them as you suggest would be meaningless. In my job I use springs a lot, but where the movement and strength is critical, as it is with valve springs, I have to use the manufacturers data to enable me to choose the right spring for the job. Installed hight and clearance between coils doesn't tell you anything about a springs capacity or suitability to do the job required of it. The critical factors of a spring is obviously it's size. Its strength. It's free length and it's working range of compression, or expansion. Mike.

Removes any ambiguity from the 10? or so dwell at the top of the stroke. -- Conor I'm really a nice guy. If I had friends, they would tell you.
