WHX?? 48,815 #26 Posted June 30, 2020 Was trying to think where you put the JB weld Richard but now I get it. Very carefully try to wiggle out those retainers. They do look corroded in but might be savable & won't hurt to try. New valves and springs should be in the kit. 1 Share this post Link to post Share on other sites

I put a "cheap " Chinese fuel pump on my 312 H and it lasted about 2 hours....2 weeks worth of mowing. I went the electric route,,,just finished it today and mowed without any issues. 2 Share this post Link to post Share on other sites
meadowfield 2,570 #28 Posted July 2, 2020 I've just received a vacuum pump, so will see if Taryls idea works... 2 1 Share this post Link to post Share on other sites
Bill D 1,921 #29 Posted July 3, 2020 I have seen videos on YouTube about that conversion. It seems to work well. My neighbors 1983 GT 1142 uses that same pump and it starts better than my Kohler's. Bill Share this post Link to post Share on other sites
meadowfield 2,570 #30 Posted July 6, 2020 it worked, well I think it did, but a myriad of other issues - made me doubt it... which may even go right back to the original issue why I thought the pump was shot!!! here is a small 1/4" thick piece of aluminium with a 1/4 barbed nipple, screwed in. Due to my other challenges - I think it worked well, though not sure what happens if the vacuum tube fills with oil??? 2 Share this post Link to post Share on other sites

Bill D 1,921 #35 Posted July 9, 2020 I had to do this on my dad's tractor today. It worked great. 2 Share this post Link to post Share on other sites
Bill D 1,921 #36 Posted July 9, 2020 Another view. I am going to rotate the pump slightly on the next bracket I make. 3 Share this post Link to post Share on other sites
johnnymag3 2,520 #37 Posted July 9, 2020 doesnt the engine oil fill the tube? Share this post Link to post Share on other sites
Bill D 1,921 #38 Posted July 10, 2020 Based on everything I have seen, I don't think that will be a problem. If it is I will mount it in a different spot. Dad used it to mow tonight and said it worked great. Share this post Link to post Share on other sites
Tuneup 1,433 #39 Posted July 10, 2020 Unless the pump is damaged by the oil, would it matter? The pressure will pulse as well against oil as air. I might try this as well. Liking the angle iron approach for mounting. Share this post Link to post Share on other sites
meadowfield 2,570 #40 Posted July 10, 2020 theoretically it will fill with oil.... however it is a vacuum pump, so should never have oil in the suction tube... I bought some clear tube to try with mine just to see! Also thought of mounting it just above the outlet, so any oil will drain back. 3 1 Share this post Link to post Share on other sites
Bill D 1,921 #41 Posted July 11, 2020 My dad said his tractor started fine today. If there is oil in the pulse line, it's not causing any problems. He's very happy. The pump only cost $25.87 from our local dealer versus $100 plus for a Kohler pump. Bill 1 Share this post Link to post Share on other sites

Bill D 1,921 #44 Posted July 11, 2020 Sorry my mistake. The local dealers are much higher. Pat's small engine has them for $119 if I remember correctly. Here is mounting plate number two that I made this afternoon. 2 Share this post Link to post Share on other sites

The nice thing about his bracket though is that the pump mounts on it. 1 Share this post Link to post Share on other sites
