Had trouble last fall. Had to use the handprimer to start the tractor if it sat for a week or 2. Installed new plunger setup.....took apart the primer and blew it with air....installed new filter.....used air thru fuel filler...fuel would come out vent...primer pushes hard are a bit...still won't start..How long in seconds can I crank the starter?// Do I crack all the injector lines next? Thnaks Joe

i have ac 200 which has same motor & stanadyne fuel system (pump & 2 square glass filters).
i also have a 7080 which has a similiar set up to
what you have. i assume that with the manual primer that you don't have electric lift pump from gas tank to square fuel filter therefore i would replace fuel filter first. prime. stanadyne injection pump is self priming ( you do not have to crack top of injectors. ) four normal cranking periods of 30 secs each should be adequate. after that i would crack the top of injector fuel return to see if you are getting fuel from pump to injector. i just had problem with air which was caused by bad rubber donuts in fuel return lines and rubber on top of
injection pump which was fuel return line outlet.
all of these must be tight & free of air. i check
lines from filter and pump and found a cracked nut. all of this corrected problem. the hand primer when worn can cause air leaks as well.
i threw away hand primer and square filter and went with a fuel manager from stanadyne. it was electric lift pump, added a check valve between tank and filter, water and fuel separator that i can dump and see. i hooked wire into electric solenoid on inj pump. when key is on lift pump works. when off pump is off. does your ether button work ? hope this helps. any ? s

George bought his Major from a an implement sale about 18 years ago for 200.00. There is no known history regarding its origins or what service it had done, but the following work was undertaken by Harold alone to bring it up to show standard. From the engine number, it was found that the major was produced late 19 ... [Read Article]
