I've been repairing engines for quite awhile now. I've seen the older engines come and go and new designs take their place in the market.
Many Briggs and Stratton engines used to have Walbro carburetors on them. I like them because most of the were adjustable and they weren't nearly as finicky as the newer Nikki carburetor I see on them now.
In fact, my old lawn tractor has a 13 HP Briggs and Stratton I/C Quiet and it has a Walbro Carburetor on it. Never had any significant issues with it. They are simple to rebuild, and they just work.
I can't say the same with the newer Nikki carburetors. Ever since I have seen them, they seem to be having issues regarding the engine's performance. They seem to have a delayed throttle response compared to the walbro and just seem to act up now and then. Almost all the engines had Walbro Carburetors except for some of the Vangaurd engines back then. Now it seems like all the Briggs and Stratton engines have Nikki carburetors.
I worked on a 31 HP Vanguard on an Exmark Zero Turn Mower that had a Nikki carburetor on it. That thing would act up any time it got the chance, and it seemed to have a dead spot at part throttle where it would shutter, even when it was brand new. I use ethanol free fuel in everything I cannot believe it is fuel related.
On many of the Briggs opposed twins I've worked on, many of them had Walbro carburetors. A lot of the older Briggs Quantum engines had Walbro carbs.
But the real question is what happened to them and why were they eventually replaced by the Nikki?
Tell me about your experiences with Walbro or Nikki carbs.
