BX19 GT carb inlet filter orientation

[pepo111]

I'd left my BX19 GT out on the lawn for over a year as the garage was full. When parked up, the engine ran fine and had driven the car around often, but it was always really hard to start. I finally got around to moving it off the lawn and into the garage and it just would not start.

I pulled the carburettor apart because there was no obvious squirt into the carb and I thought there might be a blockage. On disassembly, I discovered what looked like a tubular filter inside the fuel inlet which seemed to be oriented back-to-front with the capped end facing inwards. I could not blow through it from the outward side. I turned it around, the carb squirted again, and the car started quickly and ran well enough to get it into the garage. But since then, it has never run right. The other day, it backfired through the carb when I switched the engine off. I'm now wondering whether that filter was actually oriented the correct way in the first place. It must have been. Otherwise, how could I have driven it and it once it finally started, it ran really well. I can easily turn it back around but was wondering whether it was correct in the first place.

I'd turn it back around to the position it was in initially and see what happens. Maybe you disturbed something to get the fuel flowing again by inadvertently back flushing the filter when you reversed ii.

Capped end faces outwards, if memory serves? It's the same as an AX GT (assuming you still have the Solex Z1) so you might get more info on the AX side of things, but I'm 80% the capped end faces outwards, though in theory it probably doesn't make a huge difference at tickover. All it can do is starve the fuel supply anyway.
