I have recently received a Rover edger with a vertical Briggs 3HP which would have to date back to the mid '80's. It was my Grandfathers and was one of those machines that is borrowed by all and only ever filled with fuel and that's about it.
It is pretty grotty but all there.
Anyway this arvy I replaced the totally perished air filter foam and to my suprise the carby throat was spotless!! It was that blocked obviously nothing got through. I also threw in a new plug as the old one had no electrode left.
The carby linkages etc seemed to move freely.
Two questions
1/ The oil level, it has two filler plugs?? How do you check the level?
2/ I can only get it to start with some aerosol down the throat. Once it starts it runs like a charm with no smoke and no rattles. It will continue to start after that but if you leave it for 5 minutes it needs a squirt of spray to fire again.
Why the spray and it runs fine yet it won't start up again after a few minutes?
Thanks
