Hi Folks,

I was able to take my new to me 914 for a short drive yesterday. The car is a 74 with what I think is the original 2.0. It has Dual weber 40's and what I think is the stock distributor. The cap and rotor look practically new and the plug wire in good condition. It wouldn't start a few weeks ago and I pulled the plugs (NGK 7) and cleaned them, fired right up after that (Never had webers before and I think I flooded the cycling a little pumping the gas pedal thinking it would help start.

Other observations.
The few times I have started it (usually after sitting over a week) I crank the engine, and give a dab of the gas pedal to get it to fire, usually takes several tries to get. running. After warming up a bit engine goes through revs well.

On the drive the engine runs very rough usually between 2-3k its barely pulling. Lots of hesitation and at odd times it pops to live a pulls great.

My first thought is to pull the carbs, do a thorough cleaning and check to see what jets are fitted and the condition of the floats.

Also planned are a timing check, valve adjust, oil and filter, fuel filter.

Is there any other details I can provide for suggestions on how to get things running well? (IMG:style_emoticons/default/poke.gif)

Thank you!
Steve
