The same happened with Type3 dual carb engines in around 1965, which Jim noted a few months ago, when he found lots more engines made than Type 3 cars<br><br>Dave <br>UK VW Type 3 and 4 Club.</div></div><div dir="ltr"><hr><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">From: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;"><a href="mailto:jens@type4.org">Jens Vagelpohl</a></span><br><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">Sent: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;">13/08/2019 18:30</span><br><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">To: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;"><a href="mailto:type3@vwtype3.org">org type3@vwtype3.org</a></span><br><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">Subject: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;">Re: [T3] Diagnosis help for a badly running 1971 VW 411</span><br><br></div><br>> I'm not sure what the difference was between the EA and EB engines.

You would never have EC 000 001 in a 412 and another EC 000 001 in the 914.<br><br>jens<br><br>_______________________________________________<br>VWType3.Org mailing list - type3@vwtype3.org<br>To unsubscribe or change subscription options, visit:<br>http://lists.vwtype3.org/listinfo.cgi/type3-vwtype3.org<br>If you need more help, contact: gregm@vwtype3.org<br></body></html>
