Filling and flushing sounds like a good idea, only thing is it cant move and the tractor is leaning to the left, away from the drain.
Guess I'll jack it up and have at it, siphon later if I cant get it all.
I've been reading nightmare stories about these Holly carbs, I just tore this one down and cleaned it up and put it back together, guess we will see if it will work or whether a Zenith is in the future. Still cant figure out how that float rod spring goes on...
Thanks guys, good answers.
