So here’s what I got going on. I acquired a 93 350L, not running so first step clean carb fresh gas. Took care of that, rebuilt the carb, machine fires right up idles nice but there is a tick coming from somewhere. So first assumption is that it’s not getting oil, the oil line is a mess, could be clogged filter, collapsed line whatever. So I have a new filter and new line, but how can I determine if my oil pump is actually working??? Or am I better off just blocking the pump off and premix? What all needs to be done to convert to a premix machine
