Hi Scott, just checking into the thread. Dust collection looks excellent and I like your hangers. Even if time consuming they look great and I think its worthwhile.
I have a couple (4 is a couple right? lol) of red tractors of various flavors, I have used Berryman's Chem Dip with good success on carbs. Essentially its a 1 gallon paint can which is filled around 2/3 full with a wire basket. One puts the carb into it overnight to soak. I can't tell you what exotic blend of solvents is in there but it works wonders on fuel gum. I have bought this at CarQuest and I think Napa once in the past. I usually follow the dip with a wire stolen from a paper wire-tag. Poke thru all of the holes, usually only two circuits, idle and main, then the air blast to finish.
That engine looks impressively clean like it was never run, or was cleaned up to be a "good spare" and then shelved. One thing rodents don't like is solvents....so that tells me there was not a lot of gasoline in that motor. In any case a flathead engine is a little torquey monster in good tune! Have 2 of them, a C60 in Farmall Cub and a Y112 in Clark Forklift.
I thought you might use the electric chain hoist to get the engine mated to the stand, but those hydraulic carts are very handy. The two of those devices combined would be very effective tools if you ever have to split a tractor...do your models require a split or does the G have a frame structure independent of the engine & trans?
I'm also in admiration of your super clean drafting table. I have a Mayline version with a parallel rule (cable aligned thingy) and due to me it became a desk to collect junk and sits in storage due to its rather large size.....Someday
I'm finding the Virus Shutdown to be somewhat therapeutic. I'm advancing a lot of projects in my shop! I can't imagine being cooped up in a house or apartment without some outlet......
