Hi NormK ,
They overcame this with a remote primer bolted to the chassis. Your one must have been in the window of time where they first introduced the G4 carburettor set up with the grey primer free float chamber cap without a remote primer. If someone has retrofitted a white cap with primer button, then you can reach it with your finger with some difficulty, if the hot start position on the throttle control won't do the trick.
I would only convert it if I could locate a decent cover with the factory made snorkel port, otherwise I'd put up with starting it without a primer or try to get a remote primer to set up.
