Here I’m faced with the same problem as before, the old one is stuck fast to the broken carb. I could go at it and break it off, if that’s what it takes, but long-term I’m not going to be able to maintain the cycle in this way.
I’ve tried grips, unsuccessfully, and thought about notching it and tapping it with a drift, or screwdriver. In theory the ring should expand when heated, say with the kitchen blowtorch, but this has developed a gas leak and sets fire to my hand whenever I try to use it. An alternative might be to place it on a heated griddle for a minute but we are talking about part of a fuel system here and, again, it just doesn’t seem right. Let alone my lack of knowledge about precisely what the alloy is.
A strap wrench might give enough purchase and without damaging the surface. It’s clear that I need firm but gentle solutions that may be useful elsewhere, so I’m going get one and give it a try. I’ve checked to make sure I can get a replacement if it all goes wrong, both eBay and Hitchcocks can oblige, for under a tenner, so Plan B is in place. It's always good to have Plan B, think of it as panic prevention.
