when i first look into this motor there was not intention to build this motor. just to make it run good. i think for the most part everybody would agree this motor run's like crap from the factory. it seems like 99 percent of theses motors are found on med to large two seater gokarts. i have 5hp on a med two seater and my neighbor has a 6hp on is large gokart and they both run the same way. fix jet and governor way down and only a 20 degree advance timing and for anybody that does not understand what i am talking about. i would say pretty close to chitty chitty bang bang.....:laugh:
first thing i did was look into the head. actually the first thing i did was to find out why it did not run. engine only less then a hour running time and then the owner replace it with a new engine and put this one back into the factory tecumseh box and then it sat for over 10yrs+ until i got it. keyway was broken....:doah:
right away i notice the casting on the intake was much lower then the exhaust
