ROOKIE..LTX1045, No START
Hello Folks...New Rookie here.
Product: LTX1045 Engine: 20hp Kohler Courage. "No Start" issue...Here we go!!! Last October, mowing, running fine..here some metallic noises...shuts down.. Initially thought it was electrical..again, ROOKIE  ..New solenoid. ..New Starter. Investigate more, removed valve cover, discovered broken, fractured rocker arm on Ex.side..Investigate further, discover bent push rod, look through push rod tunnel..no push rod lever  So, I remove engine cover,(Lid??) to expose cam gears and the fun stuff.. Drain oil..make sump(oil res) shinny and clean!! Replace Ex side came gear because the rotating finger was chipped and scared from the push rod stabbing it (exposed cam from broken rod lever).. Replaced cam gear in proper position(New) Replaced new push rod lever. Installed new gasket for cover(Lid)??and socked everything up nicely. Replace Fly wheel(new) because when I rapped on it to remove from the shaft, three magnets broke free from the wall and wanted a new one rather than trying to re adhere, locking key is in position and fly wheel and shaft are ONE!!..at this point I've been double checking all my work, then triple checking, then, when through, double checking.....Ok.. Replaced new valve, new rocker arms, new push rod, new head, new valve cover gasket...set my rockers to correct spec..Button everything up..replace new plug...I DO HAVE SPARK...fresh charge on battery...Turn Key!!!!! No start!!! she cranks strong and beautiful and healthy like she wants to fire, but won't...installed new starter module, just cause...was thinking a fuel issue?? I removed fuel line going into carb,...good,strong flow... I spray engine start into carb, not even a giggle or temporary start,..just crank and crank and bang!!!loud single backfire...My gas in the tank is old(six months sitting) I have new gas on hand and and new carb.kit...I would like to flush the tank and lines(fuel), replace fuel filter and install new carb.kit.. All new parts: Exh.side Cam gear Exh.side push rod lever Push rods Rocker arms Exh.side valve Fly wheel Starter Mod.(have spark) Solenoid Spark plug I don't think this old, diluted watered down gas is igniting, that's why I would like to do the flush, maybe the gross, gummy fuel is complicating the function of the carb. delivery system as well. that's why I would like to replace the carb as well... Are there any electrical issues or target suspect switches or connectors I can disconnect and re-connect???? I haven't messed with OR have ever had an issue with wiring or connections but, am certainly open to ideas!!!! Again....Strong, healthy, clean crank....but no fire, she wants to but won't...But why cant I get a temporary run and hiccup with a blast in that carb.choke flap....This is why I'm here today folks. Again, I'm a rookie and wanted to exhaust all my sources and replace all parts I was running into with each step with NEW parts...parts that did a good job, but their life expectancy was up...THANK YOU TO ALL WHO HAVE TAKEN THE TIME TO READ THIS..any and ALL ideas are welcome.. Thank you again for all your time you have invested in reading this sad, pathetic boy's tractor troubles story...Thank you folks.. Respectfully, Andrew

When you installed the cam gears, did you align the timing marks as directed on page 66, bottom right, of the manual at this link.....

Yes Sir Ironman....Aligned shaft at 12:00, key facing me..Right side gear aligned at 4 o'clock position with gear dimple marks matched with shaft dimple marks..other side as well in the 8 o'clock position...I turn the flywheel manually when adjusted the rockers and still fill that pocket of resistance for compression...thank you so much for your time....need more ideas!!!!

OK, I think my next step would be to re-check the rocker arms (.005 intake, .007 exhaust, at TDC). If they are good, next I would pull the flywheel to make sure the key didn't shear when you got that "big bang". And by the way, when you put the flywheel back on, the crank and flywheel hole should be crystal clean (i.e. no grease, etc.)

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
