Just a word of caution on that Tillotson carburetor – it was made prior to 1930, which is when the diecasting industry got around to adopting some alloying standards that improved the castibility and longevity of the zinc alloys they were using to make various parts. Many models of Tillotson carburetors used on motors built in the 1927-30 time frame were notorious for breaking down and comping apart. The MS-20 carbs used on the Indian Silver Arrow as well as many Evinrude models were known for disintegrating over time even if the motor wasn’t being used. The weakest points were the throttle and choke quadrants and the float bowl. The float bowl in particular was a bad spot, if a person was the least bit careless when it came to tightening up the fuel fitting, the entire side of the float chamber wall would break right off, rendering the carb completely useless.
Two broken pieces from two different carbs, but t he fracture lines are similar, suggesting repeatibility
I have retrofitted the Tillotson MS-45 and MS-45A carbs onto many motors that suffered broken carburetors because of the “zinc rot disease” (proper name is “inter-granular corrosion syndrome”). So handle any Tillotson carburetor of that era with kid gloves, and use two wrenches to tighten the fuel fitting onto the fuel bowl – one to tighten the flare nut, and the other to support the elbow that you’re tightening the flare nut onto.
