Hi Syco. I managed to get the engine unseized this afternoon using a heatgun. I used wd-40 at first as well as sewing maching oil but that combination didn't work, until I applied heat for about ten minutes going all over the engine without melting any plastic from thte ez-start housing . I stripped 3 screws trying to remove the housing. I bought more hex wrenches thinking some of the tools I was using were bad. Thanks
