[QUOTE="Scott Cee, post: 133998, member: 23817"] I made a cute little bracket and added a fuel shutoff valve. I was concerned about the needle valve in the carb leaking and filling the engine with fuel, this also might have happened to the prior engine and been part of what damaged the bearings: [ATTACH type="full"]6237[/ATTACH] The other thing I did to help get it to run better was switch from ported/semi-ported (I don't honestly know what you'd call it) to manifold vacuum for the vacuum advance in the distributor. This means there is a pile more timing when running at part throttle, and it will retard some from there when going to full throttle/high power. This makes way more sense than where it was pulling vacuum from before, and reading the manual it would seem like this was what actually was intended. Lots of timing at part throttle is good, the engine likes it, it burns more efficiently and cleaner. Up to you if you do this, but it really helped mine run better. I also threw about 10 degrees of base timing at it this way: [ATTACH type="full"]6238[/ATTACH] [/QUOTE]
