no unfortunately i dont... i dont have a tach, so no numbers. What i could do is get another jug and bolt it on when i get my tach. I was really wanting to see if this mod will even hold up, cause im afraid that the ring doesnt have enough support. I really need to get a mount for this thing. Do you think that making a mount kinda like a glow engine will work? and have it bolted onto the jug. or should i make stand offs. I dont want to use a plate mount, cause i dont have a carb spacer so the throttle will open all the way.
