So I got my '75 2056 back from the machine shop and began dressing it up. I tested and cleaned some fuel injectors and found that I have 4 good ones. (IMG:style_emoticons/default/piratenanner.gif)
As I got to fitting the cooling tins, I found that the cylinder heads are on backward. CHT sensor is supposed to go on the 3-4 side... (IMG:style_emoticons/default/headbang.gif) I think I've seen this problem on here somewhere but can't find it now. The immediate concern is the wire location for,the CHT sensor. I'm thinking the only correct way to fix is to take everything back apart and switch cylinder head sides. If I had ample time to work on this, I wouldn't be so frustrated.

IMO its not worth trying to drill/tap the other head. Cut a hole for the wire in the other tin and extend the wire.
Which head it goes on makes no difference to the FI brain as it's only a warm up enrichment device. Once it's above a certain temp it has no more influence on the fuel mixture. |

I was thinking warm up only too. So it is not the end of the world, just not perfect. HAM reworked my 1.8 heads and He forgot I was using FI and closed up my hole. (IMG:style_emoticons/default/blink.gif) So I had the same issue, but caught it before installation. So I did the drill and tap thing on #3. I think I got the drill and tap from the same place. The tap is limited so the hole really needs to be the correct size. |
