And this is the problem with the design of these things, you can pump on the primer and you have no way of knowing if fuel is flowing through the float switch, that is of course unless it is pouring out the primer and by that stage you now have a flooded motor and that needs to be delt with before you can get it started. One way to check fuel flow is with the tap on pull the hose off the carby. If fuel runs out the hose it is usually the float needle. Then as you say could be the breather in the cap, but in all my years I think I have only had that happen twice on a Victa. And if that happens the revs usually rise as the fuel flow leans out. With the float needle sticking it stops the fuel quickly so the revs don't rise because it doesn't get time to lean out
Dan, if you get stuck with the main jet screw (pretty awful design) I can send you a few bodies reluctantly through Aus Post, but I hate being ripped by them
