Thought some of you may be interested in this. This Mod. makes it a lot easier to remove and install the idle jets on 44 IDF carbs when you're calibrating them or just cleaning debris out of them occasionally. Additionally they are now magnetic due to the piece of steel Allen Wrench in them.
Photo 1 You need to buy 8 of these jet holders.
Photo 2 Buy 4 Allen Wrenches. Size: 4mm or 5/32". Cut off a piece 1.250" long or 1.170" long if you use "space saver" manifolds like I do.
Photo 3 Cut the threaded part off of 4 of the idle jet holders as shown on two in this pic.
Photo 4 Tin the ends with hard solder or mild silver solder then solder one of each jet holders onto the ends.
Photo 5 This shows the new jet holders with "O" rings and idle jets installed and ready to go back into your carbs using an 8mm combo wrench
Photo 6 The installed holder, easily accessible now with an 8mm wrench and retrievable with a magnet if you drop it.
