I bought a set for my 1.7 motor which replaces the missing 2.0 if motor.
I bought these a couple of months ago but have just got around to engine work. This evening I got them out of packing tonight and I think I have a problem. I set them on their manifolds but it looks like they are single sided. They are Italian stamped, 40 IDF. A search finds that they are likely off a fiat or alpha. I did however find a link to a 356 thread which is short and inconclusive. Has anyone fitted this type/model with success? I'll try to get pics uploaded asap. |

You definitely have either the wrong shafts, or the OP modified them.
On my 40 IDFs, I can put: a bearing endcap washer, spring washer, throttle return spring holder, a thick washer, AND Cris's pulley on my shaft with plenty of thread left over. (IMG:http://www.914world.com/bbs2/uploads_offsite/i366.photobucket.com-10819-1476297510.1.jpg) On your carbs I think you could barely put cris's pulley by itself with enough thread left. |

I'm sure the shafts are correct for the application the carbs were built for. I've dealt with this circumstance already and I don't think it will impair proper installation of my kit. I have special throttle stop plates which are thinner than the standard ones. They allow my pulleys to be attached to short shafts where the stock (double layer) plate doesn't leave enough threads. My stop plates aren't part of the kit and they aren't listed on my website but they are described in the linkage installation instructions. |
