help max4 stall on incline

[new2memax4]

well what else do ask my max 4 18 hp vanguard recently started to stall on hills.fairly steep and short my engine just seems to want to stall. if hill was any longer i would suddenly find myself going backward thinkin oh %#&t. Does anyone hav an idea what would cause this?? seems to be new problem cuz i have easily climbed these banks before. I am getting better and braver and braver and am approaching these banks at different angles,but this thing is definatley stalling. any insight would be greatly appreciated.

It could be a low oil shut down if your engine is running lower on oil. After that I would think maybe a fuel problem. How steep is it? Does it shut down the same if you go in reverse or maybe inclining the other way? I ask that cuz maybe a wire shorting out if it only happens one way.

fairly steep 30-35 degree ?creek bank, never thought to try it backwards? scary thought ,although i did slide down backwards once cuz we all but stalled. was reading and someone else mentioned oil sending unit and or oil level. Thank you i will check oil tommorrow and see if ican find the sending unit .I do not know where to look for the sending unit if it has one.

thanks for the info. I checked the oil and it is right at full.I remembered i had put gas in a couple days ago,when i got this machine i had alittle trouble getting to idle and not shut off when the throttle was released from flat out run speed. What i remembered was i had run some seafoam thru it and put some in gas tank.I put couple onuces of seafoam in and headed for the creek,no problem today on same banks.The only other difference was maybe half hour run time , I was not out in the creek playing around for 45 minute like yesterday before tring to climb the bank. Thanks again for the advice.One more question,Do the 26"tires really swim that much better than the22" on max4?? I live creek side and really would like to have this puppy swim alot better than it does with 22" rawhide3 on it.I think it was Larry w that signature states he has 26"tires. Do you get it in water much and does it sacrifice power or anything else to run the taller tires?

oops sorry that was RDR that states 26"tire on max 4. does it really swim well and still climb steep banks?Mine is an older one round headlights pass thru bolt in axels and 18 hp vanguard.
