Blake,
What intake filter? We have already mentioned questionable non marine parts the PO has installed. If you are talking about the thing that sits on top of the carb, it's not a filter nor is it replaced. The USCG flame arrestor is cleaned only. Please post some pictures before you drive a potential hazard.

Sounds like some good progress. Like we all said before, with a boat that old you'll find multiple problems. Get everything addressed and you'll have one extremely reliable unit. I didn't like the look of the DUI because it's bulky but it's an excellent addition if you really want to go the EI route.

Like Paul said, make sure to test the voltage to the coil running and that will tell the tale if that's the issue.

I just completely re wired/re structured my 85 dash. Got rid of all the daisy chains in favor of some different style connections. If everything is in nice shape and the gauge is correct you should see 13-13.5 volts on the gauge running (actual alternator output)

Mike,
To clarify, there are two items that can get plugged back at the tank.

The first is the anti siphon. It looks like a fuel line fitting where the fuel line is connected to the top of the tank.

The second is the tank vent. It's a hose typically about an 1" that goes from the top of the tank to a thru hull fitting in the boat hull.

Both anti siphon and gas vent hoses are clear and clean. Good shape and free flowing. I'm really thinking the issue lies withen the electrical issues and if not rebuilding the carb will likely be my last hope. I plan on taking this week to rewire the boat.
