Soooo get this... pulling apart old motor to see what really happened... piston/crank etc all seem fine! Then I noticed the starting pin for the bottom of the conrod.... was in the groove where the conrod runs in the crankcase. O_O The pin is what the motor was hitting as it turned over.
It seems I have NO starting pin SPRING. At all. Not even remnants.
Is the starting pin the same as the one for the .21BB as tower lists?
Now obviously I am keeping the 454 when it shows up Wednesday, but it would be nice to have this as a backup motor for cheap.
My main concern is - where is the spring? Turned to dust? I still seem to have the same compression I did before when the motor was running...
Everything seems to roll over smooth, when the piston comes UP, just as it creates a seal and builds compression, there is a little 'click'. It's TINY...
And it happens everytime it makes a seal past the exhaust port and if I wiggle it right there it clicks up OR down. Almost like the sleeve is moving an extremely small amount?
Is that possible? Is it worth buying a new OWB and pin/spring?
