A Few /6 Questions

It's not really a "tic" but more like constant music of the solid lifter engine. It will be louder when the engine is cold because of the heat expansion issues. I have heard arguments for and against various uses of upper cylinder lube like marvel etc.... Not some much lubing fuel system parts as it is the valves. Too much additive can cause damage to valve heads and seats. You should lube your carb's throttle shaft from time to time and even a little shot of ATF down the bowl vent ever so often won't hurt. Moderation is the key....
