I have a 1975 914 2.0 with Weber Dual 40 DNCF 12. When I do a compression test with the carbs, filters off and full throttle I only get 65 PSI. If I remove the carbs I get 102. I know 102 is still low but what could be wrong with my carbs limiting airflow? I've only had the car for about 7 months and stilling learning.

That's a good video. I've watched it before but it was good to watch again. I am planning on getting a leak down tester soon.
The battery I used wasn't the best but it was cranking and I was getting consistent #'s between cylinders. I had all plugs out. I will do a video the next time I test it. Maybe that will show what's up. |
