So I've got the old on there with the new one's diaphragm as the new one wouldn't start after a while anyway and as you can see it has that big yellow choke lever which is't compatible with the air filter cover without a Pita.
Anyway the new diaphragm got it going but can't keep it going. Dies under throttle and can only stay running if I play with the choke and throttle.
The shown adjustment tool that came with this new carb doesn't fit these moon looking type screws. Any tricks to turn these?
