Karl West Posted April 25, 2016 Share Posted April 25, 2016 This is a long shot I know but worth a try here before passing final judgement. I have an old Laser 61 which was down on compression so I thought that I would whip the head off to see what if any problem there was. I know that aftermarket piston rings are available from that popular auction site so I was prepared to order one to try a fix. However, on inspection, it appears the inlet valve has suffered from recession, ie the rim of the valve is so battered as to make the valve non sealing hence the low compression. I have added the photos below to show the valve lipping and how the valve sits 'sunken' in the head. So, does anyone have a spare valve for a Laser 61? Happy to provide beer tokens for part and p&p as required. Failing this I have been in discussions with Jon at Laser ref purchase of a new 70 but thought this venerable old friend deserved one last chance at life.

Jon H Posted April 25, 2016 Share Posted April 25, 2016 I would say its finished. That will probably have damaged the valve seat so not even a new valve would help. Not that we have any as the current spec valve is different I think it has finally bitten the dust Quote Link to comment Share on other sites More sharing options...
Karl West Posted April 26, 2016 Author Share Posted April 26, 2016 Jon, Thinking about it, you must be right as the valve seat has to have recessed as well to allow the valve rim to get so damaged. Oh well, time for trade in, will start saving now..........he says! Quote Link to comment Share on other sites More sharing options...
