There is a large canister on my TO 35 under the carburetor I am replacing; the work would be easier if I can remove the canister. Is that the oil filter, and can I remove it to give some room to fit the carburetor: March 20, 2016.
Yes, that is the oil filter canister, and yes you can remove it to install the carburetor. However, when you loosen the bolt, oil will begin draining from the base of the canister. You will need to place a container under it to collect the oil, up to a quart or so. After the canister is replaced you will have to add enough new oil to replenish that which drained out. I don’t recommend using the oil that drained out as it likely became contaminated with dirt.
