914 lays down..., a newbie needs some advice... Options

[splashfx]

Hey guys and ladies,

I have had my 914 for over a year now, but hate to admit that it's spent most of that time in storage. Last Friday I decided to drive it to work (about 45 miles one way). It went to work and almost all the way home before suddenly (and I do mean suddenly) two cylinders stopped firing. I suspect that it has fouled the plugs - but I haven't had a chance to check it yet.

Okay, so I trailered it home and it's now in the shop. I was planning to check the plugs, and do a valve adjustment (...just because I know it hasn't been done while I've had it). I don't believe that the problems have anything to do with the electrical - I put on a Pertronix Ignitor and new plugs and wires last summer. Also, I plan to look over the vacuum on the motor and see if I can find any leaks.

I'm also suspect of the fuel injection system. I'm almost convinced to rip it off and put a set of carbs on it. It doesn't seem to idle correctly, and quite often seems to be very rich (black smoke).

Any other educated guesses? I would love an expert opinion in this matter, since I'm a complete novice to these air-cooled devils and especially on the FI.

Thanks guys (IMG:style_emoticons/default/beerchug.gif)
