Thanks Dave ... others have also suggested the 235 as an option .. but think I will stick with the 216 for now .. if I keep having issues, I will definitely consider that ... but kind of want to stay as original as possible and since I already invested in two more 216's, I probably will stick with the plan to just swap engines and put in the '52 one that checked out well. I was even able to get some neat parts from the 49 .. like the old splash oiler BIG air cleaner (really neat) and the clear bowl gas filters ... guess we will be putting these on as well ...
Learning lots from you guys - thanks all for the input ...
