Hughes Engines 1.6 Rocker Geometry/Setup

Your welcome. I went to Hughes to see if I could quickly scan for the clearance amount and I couldn’t find it. There new site blows.

I did t want to state a clearance of .030 or .060 because I don’t remember it. I don’t want to give a number of .030 and that’s not enough when the engine is hot or .060 and you break through the rocker while grinding on it or worse, break it while running it.

IMO, and this is just that, an opinion, .030 clearance from the spring is enough to clear and be OK. It’s what I would do but I don’t know if that’s a good thing to do. If I tried and winged it at .030 & it broke, well, that’s fine because it’s on me.

Don’t do Jack until you get a good answer!

Do a Google search, find magazine articles and even better yet, find a racer or member here that has done it. I have not been there and done that.

Best of luck with the project!
