Re: First Project, am I doing this right?
Have you tried taking out the slack in the throttle cable with the adjusters at each end of the cable at the handle and at the carb? Best thing to do is try the throttle while holding the carb so that you can see into it to see if the barrel is lifting as you make adjustments.
I had a hard time getting mine to run with the Speed NT carb at first, now I've learned it's all in letting the engine idle and warm up. It takes less than a half a minute of idling before I can switch from closed to wide open and go. I usually start with a short trip down the back lane in the opposite direction, start up, idle through my u-turn, hit the choke and go. (It also gives me a longer running start at the hill up to the street).
