I can’t be the only person who’s struggled getting the threaded cap on Monobloc and earlier carbs without cross-threading it. The problem is that the spring clip pushes the ring off to one side, canting it over. Combined with the fine thread and 60-plus years of wear, this means lots of struggle and foul language, especially when the carb is nestled up under the tank.
Some time ago I realised that if I put a wedge between the clip and the carb top it would hold it clear, allowing the ring to be correctly seated much more easily. The ideal source for such a wedge is an ordinary plastic sprung clothes peg. No doubt others have other ideas?
I’m thinking of going into business flogging these on eBay…
Still enjoying the mag. Alan Cathcart’s recent series on Sammy Miller’s unusual bikes is excellent.

Frank may have found a photo of his famed ‘automatic idle device’ for Norton rotaries to go with your clever ‘carb cap special tool’, Ian. If so, you’ll be able to see that they are remarkably similar. Does anyone else have a nifty motorcycle-related application for the versatile clothes peg? Rowena
