budman2 57 #1 Posted October 7, 2022 (edited) Hi everyone I am at me wits end with these two toro wheel horse tractors and would like some input Please! I have a 2003 and a 2001 15hp & 121/2 hp respectively, that will not start! all I have done is thrown new parts at them and still no start! can't even get them to turn over! I have replaced everything from battery, ignition switch, solenoid and still nothing! The only thing I have not replaced is the ignition module and that is because it cost about $110. Any help would be appreciated! Thanks budman2 Been repairing and restoring these for about 20 years buy never had this kind of problem! Is it just these overhead valve engines that do this kind of stuff? There are way too many safety switches also, even on the shifter! don't know if I can bypass these or not! Help Please!!!!!
