<VV> ANFSCD: Valve Springs ?

[Padgett]

Some time ago someone whose judgement I trust said I had weak valve 
springs. This did not make sense since it would wind to the shift point 
(PG) without any difficulty but now am wondering.

Had a rocker tapping so pulled the valve cover to adjust. Let engine warm 
up then replaced the regular valve cover with a 1/3 cover to avoid oil drips.

Turned out the one that was tapping was a touch loose and stopped after 1/4 
turn but another 1/4 turn and the engine slowed down. Backed off to clack 
and engine sped back up and then 1/4 fine, 1/2 engine slowed down again. 
Wound up leaving at 1/4 turn from clack and all is quiet.

Looked at the exposed threads and all six seemed about the same, about 
three threads exposed. Springs & rockers all looked the same. Is what 
appears to be a stock 110 with about 75,000 miles.

Plan is to replace with a 95hp regular gas engine but wonder what was 
causing this. Valves had been adjusted to 1/4 turn from clack less than 
1,000 miles ago.
