BlueRu Posted April 13, 2007 Share Posted April 13, 2007 hitachi carb 2 barrel- can u swap a 1986 with a 1981 without a mod?. the only real difference that i can see is that the 86 has 2 diaphragm things in the back were the 1981 has only 1.

Frank B Posted April 13, 2007 Share Posted April 13, 2007 Both EA81 engines? If so i would say yes. The EA82 carb is bigger and will not bolt up to an EA81, EA71 manifold. Quote Link to comment Share on other sites More sharing options...
BlueRu Posted April 13, 2007 Author Share Posted April 13, 2007 yep- its the EA81 Quote Link to comment Share on other sites More sharing options...
Frank B Posted April 13, 2007 Share Posted April 13, 2007 That diaphram on the back is for the choke. So as long as the choke works, don't worry about the second one that you will have. You may also have a feedback carb(86). It has air line connections on the sides of the carb leading to the emulsion tubes. One is above the two vacuum connections for the EGR and Distributor, the other is just opposite on the flip side. Cap them. Quote Link to comment Share on other sites More sharing options...

Frank B Posted April 13, 2007 Share Posted April 13, 2007 I just looked at mine and the ports for the feedback lines are the 90 degree ones, one front, one back. Just cap them and your good. Quote Link to comment Share on other sites More sharing options...
