Hi Gadge, or the market size, as I have said,few people would ever realize the float needle was the problem, it is not an obvious problem. If the needle was not shutting off, that is obvious, but the biggest problem is the needle sticks shut and no fuel flows. This is near impossible to prove because of the primer design so it is always overlooked and people spit the dummy with the mower and give up. As for the market size, even at the price mine costs ( $1.20) I would have thought the numbers I could have sold would probably be maybe 50/100 max if I tried hard so certainly not a big market.This is why I was hesitant about ordering the ones from the States, I figured I would probably end up getting stuck with them. Once I pointed this out to thecarbymaster I haven't had a reply. All interesting stuff.
