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. |

Ummm. Do you have advance on that engine? A 1.8 person will know for sure. well if its a stock 75 it won't have advance on dist can hooked up to "advance" port on throttle body. its a cal 75 the port will be there on the throttle body but it was for the EGR. and if its a 49 state 75 it won't have the port on throttle body. as far as i know the 75 1.8 does not use the vac advance function on dist. they just tucked the hose under the distributor and left it open. they did use the vac retard side of the can. hooked up to retard port on throttle body. which is i think what van is getting at. though in his case (and mine) we have 74 49 states which use both vac funtions. that makes distributor behaviour even more interestingly complex? that NOS distributor he has linked to looks the stuff. amazed you can get it. worth snapping up. or if you know what you are doing just the internals/vac can and rebuild it yourself. i think i might go order a stash of those distributor rebuild parts. |
