857lover 291 #1 Posted April 4, 2023 hey guys i was wondering if anyone has every done a repower on a d series’s tractor i know it would be expensive but i’m willing to put a little money in to make this work my onan on the tractor does run it’s just a little finicky as i put a carb and intake from a 416 on to it …took a little modification to make it fit but it works half decent but i can’t get the original air cleaner on i did all this because the orginal carb was missing the needle for some reason and i could find one anywhere and i just want the peace of mind of a new engine like one of those twin predators or briggs 3 Share this post Link to post Share on other sites
Pullstart 62,905 #2 Posted April 4, 2023 I’ve seen the predator twins used… but I am guessing someone has got to have a carb to keep yours running. Did you try A-Z Tractor? 3 1 Share this post Link to post Share on other sites

LOTS less than a repower. I recall that the jets on the P216 and P220 carbs differed to handle the slightly greater displacement and longer valve opening of the latter, along with a couple other differences. 1 1 Share this post Link to post Share on other sites

Higher displacement with a smaller bore accelerates the airflow through the carb and can sometimes cause turbulence as well as prevent it from mixing in adequate fuel. 1 1 1 Share this post Link to post Share on other sites

pacer 3,173 #16 Posted April 4, 2023 Well..... that dont exactly say B43, but from your earlier pic, that looks like it would take the square carb which is whats on the 43's. I had one and became intimate with that dang carb, and your engine sure looks like mine. Some of the 43's had a built in fuel pump on the carb and others - like mine, had a off mount 'pulse' pump - the basic carb is the same tho. 2 Share this post Link to post Share on other sites
