Things just got curiosier. I've been talking about my new ST110 and some issues with the steering http://gardentractor...steering-wheel/ This supposedly has been garaged from the beginning though there are some small rust blisters on the paint. For all intents, its in physically nice shape body-wise.
I just picked up a parts tractor today which was left outside for quite a few years, its a ST112 Model 3112G Serial 0100332. The steering on this is ideal so I can transfer the steering parts over and all will be tight. The brake seems to be more solid of a feel than the one on the ST110 as does the shift seem to be. At least the shift appearsa to lock into the selector indents properly & on the ST110 I have to fudge a little to be sure its in gear. Both the brake and the shift might just be a matter of adjustment.
The main difference is the body on the ST110 needs some touch-up paint and it is much looser in brake, gear and steering. The ST112 needs a fair amount of prep and paint but the overall mechanisms seem to act as they should. However, the engine on the 112 is frozen. It has supposedly sat for years without being turned over. The oil is at the tip of the dipstick, not full as it should be.
I'm thinking if the 12 HP ST112 can be made to run, there is more HP and I won't have to bother swapping parts. If the engine is toast, then its only going to be good for parts. I'm not clear on how to remove the shroud and to get to the valves. If there's a bent valve, its over but perhaps the valve is just stuck? I removed the spark plug and it looks good, no carbon and there's no sign the engine filled with gas from a leaky carb valve.
Any suggestions on how to remove the shroud so I can get a good look at the engine and better, how to best access the valve cover? I'm sure the carb needs overhauled, I can do that easily, I have done that plenty on old Yamahas but I have to admit, I've never had to unstick an engine that does not budge. I'm not wil;ling to force it to see if it breaks free, I'd rather go about this conservatively.
