I have a 74 2.0 with the following engine setup:
Stock displacement Euro Pistons 8.3:1 Compression 9550 Camshaft and valve train etc Ignition is a Mallory Dizzy from Chris with wires and the Mallory Ignition box is not installed yet. Fuel, Weber Carburators new 40 IDF 28 Ventures 55 idle 115 Emulsifier (not looking for a discussion about the 9550 with carbs) Timing now 25 degrees adv I set the car at 2500 feet above see level with 27 degree timing and 93 octane fuel. I drove the car cross country to CA and trough different altitudes and then with 91 octane, so my heads started getting too hot, actually never too hot, so I had to go down to 25 degrees, with the consequents of power loss. (IMG:style_emoticons/default/headbang.gif) Lately I have even more power loss and the car is loud and misfiring. (IMG:style_emoticons/default/confused24.gif) So here my question, what would be the best carb set up for that engine and how can I tune it right, to the power it should have? Thank you guys!
