I had to get a decent charge in the battery but my old massey 35 fired up with only a few tries (I had to jump the relay as the button fell apart) A sticky choke didn't help either. The old beast creaked to life and ran pertty good but getting the 3pth hitch to lift took a bit of control fiddling (I guess it had drained of oil?) then the PTO clutch wouldn't disengage so we hooked it to my 315 baler (which is waaaaay too big for a 35) and turned the flywheel over and by running it up and down I guess the clutch unseized so now it engages and disengages nicely. A few leaks to address, and the wiring is a mess, but its gone from 1000 scrap value to 2000 fixer upper in only a few hours fussing and a tune up kit. Guess I'll go buy that reproduction seat now!
