  • / throttle linkage diagram, high revving regardless of throttle cable setting
I cannot believe i messed this up. i recently acquired a DLT craftsman with 25 hp v twin. it had been sitting idle with no exhaust pushrods ( someone borrowed them) for about 3 yrs. i removed and carefully cleaned the carb just to be safe... set valve clearances and fired it up... it sounded like it was going too fast...way too fast. i killed it, checked throttle rod to be sure it wasnt binding, and i can feel the governor shaft turn with the linkage being pushed. i might add i had another tractor here with the same carb, taken apart for cleaning... i did not have the same problem with that one. so i ruled out the wrong throttle link rod on the wrong machine. any ideas? should i check and adjust the governor? never had this before, and ive cleaned several of these Nikki carbs. help...a complete diagram of the proper throttle links and choke rod would be helpful,,, my main problem with this machine, is the id tag is faded way beyond reading any numbers.

If this is a Briggs engine the model type and code no is stamped into the valve cover opposite the the fuel pump. This is what is needed.

Start engine and hold the governor linkage to maintain a safe engine speed. Reset governor as needed. If no change then most likely the governor gear took a crap. Remove engine, crack case, replace governor gear, install engine.
