I've got an 1855A recently. Recieved 'er as a basket case, as in there were parts strewn all over the previous owners barns. It took me 3 trips to his place as I was putting this gal back togather, but finally got-r-done! The Onan on this thing is a pain in the... well.... anyway, got it running somewhat. When she runs, she runs strong. Got the eng. purring like a kitten one day, the next day it's a fight to get 'er running. After a couple months of tinkering here and there, finally thought I had it going good. Parked 'er outside overnight, went to start 'er the next day and nothing. Not even a backfire. I pushed 'er into the garage and set the heater to 60 (been couple degrees above zero here (ND)). Today, nothing, no fire, nuttin. Checked everything, all looked good so I cranked and dumped in a few drops of gas in the carb, she fired. Cranked starter again whilst pouring a few drops at a time and she finally takes off. Warmed 'er up, moved her outside to run awhile and she straightened up. She now refuses to run unless the choke is 3/4 closed so I figure I'm going to have to remove the carb and give it a real good cleaning.
Until I get time to dig deeper, she will now run at full steam and sounds reallly good! I got a deck with 'er, not sure of the size but the timing belt is still there. She has not been used for many years, I have a feeling that belt will go to pieces just from sitting/no use for atleast 5 years. That's no problem as I have a 60 inch deck on another gardern tractor. I also have a snow blower that came with 'er. That was fun finding all the pieces scattered out side the barn, but got that attached and running too. Bad thing about that is the clutch will not work. There is power going to the clutch so that's not an issue. For now I did a couple tack welds so I could use the blower this winter. Yup, with that thing running I got to say this is one dangerous piece of equipment, only way to stop the blower is shut down the eng. GOT to find a clutch somewhere... they sure are hard to find.
I also recieved a ton of manuels with this thing for all the snapper tractors, mowers, riders and pushers, equipment and such. If anyone needs one that is not online, give me a shout and I will make copies of them. I'll pull the binders out and list exactly which ones I have but there is a lot of them, I think I have the dealers binders/manuels for snapper.
