My 17 hp runs fine for 5 minutes then starts to smoke an miss and will stop runing a few minutes later
i have changed the oil making sure it has proper amount, put new air filter on, and a new spark plug gapped to b&s specs.if you run it then does same thing and new plug comes out carboned up and oily.spark appears weak or not there when it stops. wait 5 minutes put in new plug or cleaned up plug and it repeats whole thing again. any help would be appreciated. it is a b&s 17hp model#311707, Type 0132-e1,code # 98072.24ze thank-you in advance tom
My first thought is that the throttle lever is being pushed so far forward ( max RPM's ) that you are running the engine 1/2 or better choked
Look at the choke butterfly with the throttle in your normal run position it should be completely open
This may require and adjustment in the control rods or might be as simple as not pushing the throttle wide open
