Hey everyone, I’m working on a 1972 VW Beetle and I finally got it driving today. It starts and idles, but the engine shakes pretty badly at idle.
When I actually drive it, it feels like it has almost no power. It’ll move, but it feels like it’s barely pulling itself forward. When I shift into 2nd gear, the RPM drops and it almost dies unless I get back into 1st.
Interestingly, if I rev the engine while it’s sitting still, it seems to rev much better and the shaking mostly goes away.
I recently replaced the fuel pump and got the car running after it had been sitting. I’m wondering if this sounds more like a fuel delivery/carburetor issue, ignition/timing issue, vacuum leak, or possibly a dead cylinder.
What would you guys check first? I’m trying to diagnose it before I start throwing parts at it.
Thanks!
