legoluke.11 Posted January 16, 2018 Share Posted January 16, 2018 Hi guys the engine on my hyper 7 can’t hold a tune, and when trying to tune it it’s very sensitive, like 1/8 of a turn between gasping for fuel or bogging down. Is my engine on the way out? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

locky Posted January 16, 2018 Share Posted January 16, 2018 Check screws holding cooling head, backplate and carb are tight. Try using new glow plug, fresh fuel. Try removing needles from carb, clean and replace o-rings if needles are really loose. If it ran well before then probably carb issue, but best to eliminate others. Check fuel tube for splits. Check fuel tank lid is sealing. Quote Link to comment Share on other sites More sharing options...
