I'm putting the finishing touches on my first ever engine swap. It's kind of amazing, but she fired right up, as soon as I cranked long enough to get fuel to the carb! Now for the (potentially) bad news. Standing next to my Scout, I reach through the window, make sure it's not in gear, and turn the key. She starts up with no hesitation. (I love the sound of open headers!) After adjusting idle by ear (haven't installed the tach yet) everything sounds great. But, as soon as I climb in and push in the clutch, the engine revs up to at least twice the RPM! So I let the clutch back out, and the RPMs drop back to normal. I check again, and the transmission is definitely NOT in gear. Now, I haven't adjusted the clutch yet, and I'm out of the state until July, so I can't try anything yet. I'm just brainstorming with you guys, because this is so weird. Even with the clutch not yet adjusted, with the transmission is in neutral, what could be bogging the engine down so much??? Background: I threw a rod in my 196 a month after buying my 1980 scout. I've spent the past 9 months swapping in a 345 from a '79. I got a flywheel and clutch for a V8, as the 4cyl setup is different. I didn't touch the transmission; it was already in my Scout, and drove fine. Thanks, all!
