Dcsheffield Posted March 22, 2014 Share Posted March 22, 2014 Sounds like the disc valves are not seating properly, might just need cleaning. Any dirt under the disc allows pressure to leak back. Link to comment Share on other sites More sharing options...

yellowperil Posted March 24, 2014 Share Posted March 24, 2014 Id go with cleaning the carb on the one that wont start. Its usually rust in the carburettor bowl that gets stuck in the jets if its been stood. The advice about the other is spot on too. If all the discs dont seat then youll get no pressure . Im repaired a few of these and im a former power tool engineer if you need help. Link to comment Share on other sites More sharing options...
