Hey all, its been awhile since I have been around, I now come with a question...

I have an '86 F-150 that was converted to propane at Comox Valley Ford with only 26km on it They used an Impco Model E, VFF30, and a 225 mixer. Currently it sits at 371,401km on the original 300 and I assume fuel system as it still has the green braided lines. I bought it in the spring of last year, and just now insured it.

So far, I know the regulator/vaporizer was rebuilt at some point(it doesn't leak) as I have all of the old gaskets here, I don't see much if any wear in the mixer either.

My problem is, I did a full tune up, plugs wires, cap rotor etc following the specs on the ICG tag under the hood, I just ran it through its first tank of fuel and that lasted all of 280km. Any way to lean this thing out? I'm pretty sure it has been messed with.

I'm basing this off of my experience with my big block Dodge though so I could be wrong.
