It sounded like my LSN was lean so i richened it up about 2 full turns and it worked, but it would still cut out when i pull to full throttle right away, so is it OK if i richen the LSN even more. And i was trying out O'Donnell R2R fuel, but i think its so oily, thats why my engine is cutting out? And there is a good amount of smoke coming out of the exhaust .
