Oh for the days when the Brigs had a carb with a fuel/power adjustment screw to set how much fuel she got grrrrrrrrrrrrr

I have a Husky Zero Turn with a Kawasaki Twin V 21 which I think is 25 HP.....Recently she began starving for fuel, you know, bad idle cuz she hunts and the govenor keeps revving her back up,,,,,,,,wont run right wide open or when mowing unless you have the choke maybe 1/4 to 1/2 out, Im sure yall get the picture???

I already tried the easy stuff, checked cleaned n blew the fuel lines on BOTH sides of the filter and fuel pump n she has good clean flow there,,,,,,,,gumout down into the carb via the inlet fuel line,,,,,,,gumout via the carbs air intake,,,,,,,air n clean n gumout in the lines and carb inside n outside to the best extent WITHOUT removing the carb (looks like a 2 barrell).......

BUTTTTTTTTTTTTTTT I cant find any external adjustment screws such as the power/fuel adjustment in the bowl or venturi etc area ANYWHERE GRRRRRRRRRRRRRRRRRRRR Its the kind of problem where in the old days you would simply turn the fuel screw out 1/4 turn and no more leaning out problems

Ive heard somethign about valve lash adjustments on those overhead engines but it seems more like I need to turn the power/fuel 1/4 turn out BUT THERE IS NONEEEEEEEEE

Please help meeeeeeeeeee

Ol John T and all

John.the main jet in carb is pluged,see it all the time in the shop.pull carb apart and clean all the small holes in the nozzel and the hole in the main jet.use carb cleaner and a air hose/gun.if done right should run like new.

No adjustment on the Kaw. John you just have to take it apart and clean it(this da__m ethanol gums these little carbs quick. I don t know which engine you have but most are single barrel and run a Y pipe to the two heads. The one I had apart today has three main jets stacked in the carb body. The one that was plugged today was on the top of the carb and looks like a plug. Good luck. BTW I am dumping a little ATF in the gas to see if it helps keep things running.(I have 40 to get ready for a spring sale)
