1975 1.8 with L-jet - Have had idle/vacuum issues and shop is telling me advance is not working. OEM replacements not quickly available, so they're suggesting a Permatune replacement. Any feedback on this unit? Thanks.
P.S. Shop works exclusively on vintage Porsche's. Owner is long-term 914 owner and 914 concours judge. |

I decided against the 123 for my L-Jet because of the lack of proper mapping and it doesn’t have the ability to read both advance and retard vacuum. I went with the Pertronix Ignitor II and couldn’t be happier with that decision.
But, I know vwnos can get you a fully restored distributor and has NOS vac cans: https://www.vwnos.com/022-905-205-ab The above link is your distributor with new everything. |

Yeah he’s in Houston. It’s mostly VW stuff, except for ignition. In that case he has everything! A NOS vac can will be fine I’m sure. No heat cycles to wear out the spring or rubber. My decel valve was NOS and it is perfect. He has the speed limiting rotors for our year, if you want one. But I think most of us don’t lol… |
