How big of a Weber did you put on there? A K614?

The new carb was a WK614. Should have added that when the carb replaced the old fuel injection we also plugged the 'jet valve' holes which had been recommended. Just do not have enough pickup going up normal grades.

I am assuming that your running a full flow air cleaner. You may need to increase your main jet size, and raise the float level slightly, as with all carbs this is trial and error. Do you know what size is in the carb? If not look in the paper work that came with the carb it might tell you there in the specs. Altitude also pays a big role in power
