mmmmmdonuts 274 #1 Posted January 30, 2015 I have a 1968 Raider 12 tractor and am having problems getting it to start / stay running. I replaced some of the fuel lines and put a fuel filter and cleaned the carb and had it working in the summer twice (mowing the lawn for 30 minutes or so). Since then I have removed the mower deck and put a snowblower on it and now I can't get it started without using Carb cleaner, which allows it to turn over and run for 15- 20 seconds and then it dies. To me it means I am not getting fuel to the Carb. I I removed the inline fuel filter, put the tank above the carb to feed the fuel pump, and have verified that gas is at least getting that far. I blew out the steel line connecting the outlet of the fuel pump to the inlet of the carb. Is there an easy way to verify the fuel pump is working correctly? It is the original fuel pump I believe and I am just trying to rule out anything else, before I get an electronic one. Could it possibly be anything else? Is it a problem to hook the Carb directly to the gas tank? (I would need to go buy some fittings that's why I haven't yet) I know this is not technically engine related but I have a bearing/bushing missing on the snowblower by the pulling. After looking through the forums I have managed to get what I believe are the correct bearings, but I can't get the pulley off the shaft to put the bearings in. Is there an easy way to do this? Or do I have to dismantle the entire shaft to do this? Thank you. Share this post Link to post Share on other sites
wallfish 18,191 #2 Posted January 30, 2015 You can easily verify the pump by diconnecting the feed line to the carb and cranking the engine. Disconnect the coil or spark plug so it doesn't fire up (Just in case it decides to now). Best to run a piece of fuel line or hose from the pump into a bucket or something so fuel doesn't get all over if it is pumping. If the tank is higher than the carb, you can connect the tank directly to the carb. Only issue with that is if you are going up hill and then the tank could end up below the carb. Might also be a good idea to remove the carb bowl and check for water and also make sure the float needle isn't stuck closed. Possibly clean the carb again, new gas is horrible now so carb cleanings need to happen MUCH more often then they used to. You'll need to get that pulley off to change the bearing. Soak with penetrating oil, heat, use a puller or a combination of things. Share this post Link to post Share on other sites
mmmmmdonuts 274 #3 Posted January 30, 2015 Thank you for the help. So here is what I did. Gas tank below the fuel pump nothing would come out cranking or not. As soon as I raise the gas tank above the level of the fuel pump fuel starts gushing out of the pump even if I am not cranking or doing anything. This might explain why when I have had the engine off in the past every once in a while I come back to an empty fuel tank. Does this mean my pump is bad? Or I have a bad seal somewhere and it is not able to pull a vacuum or something? Thanks Share this post Link to post Share on other sites
Ed Kennell 42,111 #4 Posted January 30, 2015 Sounds like your fuel pump is bad. They are rebuildable. I have saved several non-working pumps by taking them apart and cleaning the two check valves. If you are losing fuel, make sure it has not entered the crankcase and diluted your oil. 2 Share this post Link to post Share on other sites
mmmmmdonuts 274 #5 Posted January 30, 2015 I kind of figured the fuel pump was bad. I will try and take it apart and clean it, but I was possibly looking to upgrade to an electronic one possibly if I can't get it to work after cleaning it. Thank you.

mmmmmdonuts 274 #6 Posted February 6, 2015 Just wanted to thank you guys for your help. Just got a new fuel pump installed today and the tractor fired right up and kept going. For anyone who is interested this is the model I got. http://www.amazon.com/Airtex-E8016S-Electric-Fuel-Pump/dp/B000C1LW0E/ref=sr_1_1?ie=UTF8&qid=1423252669&sr=8-1&keywords=Airtex+E8016S+Electric+Fuel+Pump I hooked the positive wire to the ignition on the switch and before I go to start the engine I let it sit there for a second to let the gas get to the carb. Then I start the engine and it fires right up. Now onto the snow blower. 2 Share this post Link to post Share on other sites
