when the deck gets loaded the motor seems to bog, like it needs fuel. just got it, my old one was 21hp & never had an issue with this situation. this one a 22 hp struggles under load (uphills too). dont see a power screw on the carb . anybody ever jet one up ?? common problem? 150 hours, clean air & fuel filters. no crap in bowl or existing jet. thanks in advance

Back blow the fuel supply line from the tank. These lines collect debris over time and gradually starve the engine for enough ful to work, especially under load.
Also check the crankcase pulse line from the valve cover to the pulse fuel pump for any cracking. They do crack with age and will do the same thing.
Ultimately, the fuel tank needs to be removed for a proper washing out, then reinstalled.

thanks, still waitin' on plugs but looked at all that. mower not old , fuel filter is clean as is the tank. although the way it acts i still think fuel is the issue. my old wheel horse thats used in spring & fall for leaves has a power screw that needs tweaked every now & then acts the same way which is why im leanin' in that direction. if plugs dont fix it this carb will have one too till im done.
Failed plugs do happen, but, hardly ever fix anything. Clean yours and check them for spark before pulling the credit card.still waitin' on plugs
Hope you didn't get on Scamazon and get plugs. They are highly cloned items (NGK and AC Delco). Go to a real auto parts store.
Never seen one.dont see a power screw on the carb
Normally need to jet down using a high altitude main. Most of the worn out mowers I get are rich runners with new air filters, choke wide open and clean fuel systems.anybody ever jet one up ??
Do you have mice chewing wires at your house? I would pull the top engine shroud and look around if so.
alright boys, plugs came today & fixed the problem. right side came out lookin' black & funky, left side looked good. mowed the front yard as a road test, pulled that one out just to look & it was nice & clean. who makes the Briggs plugs? thats what was in there & what you find in most mower places are Ch------ns. never liked 'em, never will. Quit usin' 'em years ago when doin' a tune up on a customers car and "installed" a miss in 2 cylinders, and was them freakin' junk ones i just mentioned, new in the box. fast forward many years to find their brand of gap tools (the round ones) are junk too. used a mic & found "em to be way off & no 2 the same, once again after running probs occured. by the way Autolites.Failed plugs do happen, but, hardly ever fix anything.
