Yes, I think you burning or most likely pumping exessive fuel out of the engine. You need somebody to help you. As you crank the engine it would start, and at this time you need to reinstall fuse. If you get this timing just right the engine would keep running with heavy gas smell. After a minute or two everything is back to normal. I was never able to start it the normal way - the battery would go dead cranking this big V12.
