Anglo Traction 761 #2 Posted March 28, 2013 (edited) If yours is the Metal type pump, then they can be rebuilt. Have you checked the Oil to see if there is fuel mixed in it ?. ...... If the diaphram splits, it will leak fuel into the sump. When did you last use the Tractor and was it working ok then?............. You can also check to see if there are oil deposits in the Carb Venturi. If the Fuel Pipes, Filter etc are old, it may be worth draining the system and checking for blockages etc first. Take the Pump off and open it up to see what it is like and check which type it is. I have had the problem of the diaphram failing with one of my Tractors and have obtained a Rebuild Kit from the U.S., but not had chance to fix it yet. I got them from here- www.maritimedragracing.com Edit----- Scratch the above link and try this one click on Fuel Pumps select Kohler Pump on next page...opens a PDF File. You can then contact via E-mail...... http://www.maritimedragracing.com/then_and_now_automotive.htm Let us know how you get on and we'll go from there.

wheeledhorseman 579 #3 Posted March 28, 2013 Here's another thought to add to Richard's The diaphragm may have given out over winter but it could be that the valves in the pump are getting tired. The tank is under the fender I think, and fuel can tend to drain back if left for a while. The pump dries out and if it's getting old simply won't prime itself. Here's something to try that's worked for me but I leave you to do your own risk assessments and method statements! Remove the hose from the pump to the carb and replace it with a short length of hose. Make sure the tank valve is open then suck petrol through to the pump. Listening carefully it's sometimes possible not to get a mouthful but not always so be prepared! Petrol in the mouth isn't pleasant but like many others I've lived to tell. No naked flames though. Reconnect the pipe to the carb and the pump will more than likely function again (unless as Richard says its the diaphragm) If the starter was only turning the engine slowly it's worth remembering that 30 weight oil gets pretty thick in cold weather. Also very important to make sure that the engine isn't also trying to turn the gears in the transaxle where the oil will also be very thick ie have the parking brake on to disengage the drive belt - easy to forget this.

meadowfield 2,756 #6 Posted April 4, 2013 Hi, the pumps can be a bu££er to prime, if you look on the forum you'll see a few threads on this. Thet really struggle sucking air and fuel from the rear of the tractor. Lifting the tank higher than the pump works, filling the tank to the top helps. Andy and Richard are right, when the valves start to deteriorate the fuel drops back easier and you always have to crank a while to pull fuel through. When you take the pump off can you trigger it and feel a vacuum with a finger over the nozzle? I've rebuilt 4 with reasonable success, dirt and water have been the main issue. mark Share this post Link to post Share on other sites

Andy hehe, that's my method! the other ways are pour fuel in the bore to start - the engine then cranks hard enough to prime the pump. The other way is the pressurise the tank using your mouth like a trumpet and turn the key.... (brake fluid and nitro fuel are far worse by the way) Share this post Link to post Share on other sites

Anglo Traction 761 #9 Posted April 4, 2013 thanks lads for all the help, just got it going now(16.30) had to blow back from fuel filter to clear petrol cock in tank, next job now is take the tank off an clean wash it out, now just wondering wether to do a complete restore or leave it in its working clothes.what do yourselves think thanks for now Allen Glad you've made progress on getting it sorted Allen. Before we can suggest what to do with Rebuild and Paint or leave it as is, we would need to see pics of it's condition. Pics are all important here..............'cause we like 'em Share this post Link to post Share on other sites
