Re: NEw (OLD) Sears SS16 Onan Tractor
I wouldn't worry,I have an 25 HP Onan twin very similar a friend traded me for a winch and some work--it had sat 15 years in his shed when I got it,and it sat 5 more in my garage,before I finally tried getting it running,to try and use ,to run a huge air compressor..I figured the carb would be junk,but it wasn't
I did not even have to take it off or clean it--it started after cranking it over about 15 times on choke,and it did flood once--after it ran about 30 seconds I heard it start smoothing out a lot better--I added some fuel system cleaner and marvel mystery oil to the gas,and it ran great for an hour or more..(I just pray it runs as good next time I go to run it,after sitting another 5 years since then!--the air compressor project was abandoned)..
I've had to get a few Onan's on motor home generators going after long neglected periods of non-use,and it was not diffucult to clean the carb,getting them OFF while in that cubby hole compartment was the worst part of the job..some have cork floats that are likely to be very fragile,and possibly no good,they tend to get "heavy" and sink with age,gas soaks into them...a brass one is a lot better...these engines were made for heavy duty industrial use,and can take abuse and long "downtime" pretty well..but if its been left out to the weather,anything will need restoration of course..
Looks like you found a diamond in the rough!..I'm very tempted to put my Onan on a parts Suburban I bought that originally had one on it,as far as I can tell,by the chassis being different where the engine mounts to it..but I'll need a second parts tractor to complete it,its missing a lot of things..
