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?

You will find lots of carb info and jetting guidance here if you can spend some time doing searches, or people will pop them in eventually. Altitude matters...
SOT, where did you get the air hoses for the blower in that first pic? |

Agreed, maybe someone else will chime in. Try some seafoam for a cleaner. I have some fogging oil for storage but I have not tried that for cleaning, not sure if that works, but you can spray in right in the carbs. |
