Jacob, it sounds to me as if you probably have congealed lubricant in the engine and needle valve. I would suggest that the engine has been sitting in the distribution chain and the lubricant had congealed. I would flush the engine, remove the glo plug, I use carb cleaner in a spray can to clear the mess out of the engine and oil well afterward. Also make sure the needle valve is clear, using the carb cleaner to blow through it and a wire if necessary. If it is a throttle engine, I would clean the throttle as well. The bearings are probably loaded up too but once it runs, the heat and fuel will clear them. Hope this helps. Bob
