carb jetting question for B&S 2 cylinder engine
i have a Briggs & Stratton 44N877-0003-G1 with the auto choke, so its not the 2 barrel carb, its the single barrel carb in it
i realized the main jet has fallen out so i used a spare from those standard carb rebuild kits for the 14-20hp single cylinder inteks
well the engine runs sorta as it should but clearly the jet is too small since at full throttle its only running like 1/4-1/3rd speed at best
i found another jet i dont know whats its from but it must have been a 20-21 hp since you can see the hole is noticeably larger so i'll try that in it when i get a chance.
my question is, if anyone knows, since i have at least 2 different size jets, how many different standard sized jets are there?
im assuming that the small jet size was for 14-17 hp and the larger jet size would be for the 18-21 hp but would that be enough flow for a twin cylinder engine?
You can only learn if you ask the question, so there are no dumb questions.
