Umm... The parts may be more than repairing engine is worth..... This is why B&S is failing.... I bought a log splitter with dead B&S and the cost for parts to repair was more than I could buy a "disposable chinesium" engine....
Was not my greatest move as I am not a fan of a lot of Chinese stuff, but over $200 for just a bag full of carburetor parts (carb body, fuel tank, air cleaner and miscellaneous do dads for linkages) for a 30 year old engine was just a bit more than a new $130 engine (and 1.5 more fresh hp - from 5hp to 6.5hp).......
And was direct bolt up to B&S or Honda specs...Only negative is placement of run/stop switch as it sits on my log splitter, may not be issue in other applications...
Please forgive me for going over to the dark side....
