bogging down almost stalling

[gokartcrazy]

i have a older yerf dog with converter why is when i run over grass and hit the gas it wants to die its bumpy area but these karts are made for that stuff ...no?is there somthing wrong with the motor? its a 6.5 power sport tes. does the carb need messing with? no power at all in grass when i hit the gas.....

Its called a 4stroke without an accelerator pump equipped carburetor.

Does it recover and keep revving?

 

[gokartcrazy]

if i get back on the street it will be normal it will recover after i get off the dirt

Check float and needle. Float level may be off causing a rich (or lean) condition aggravated by 'off roading'. Just a possibility.
A diaphragm carb might be something to consider.

My B/S 5hp (with stock carb)did this, if I got too aggressive from a roll/stop it would die, had to ease into the throttle.

Yup...Briggs suction carbs are notorious for this problem.
Tecumseh PowerSport is very different.

so what should the outcome be? should check carb or deal with it? i dont really need a a$$ ake any ways thats hard on the butt hitting all those bumps but my daughter is a rough tom boy and likes the rough ride if that didnt sound to dirty .... how do i check float level ? do i just clean jets and make sure float is free?

Cleaning jets will most probably not solve the problem. Get a manual that covers carb settings.
I have posted extensively (as have others) on this very subject.

Lol why would you want a rough bumpy ride? Just asking to bent a axle or spindle or something.

 

[gokartcrazy]

well i know every one says that the yerf dog is a yard and dirt Kart for off road and i have a older yerf kart with out shocks lol i feel everything lmao but my daughter thinks its a fun off road ride me i like road nice and smooth till my kart reaches its limit and rattles and vibrates

I had the same problem on a kart I had. It would be fine on the road but once I got offroad it would go like heck and then bog then rev then bog. You know what I did then......got rid of that tejunkseh and put a older briggs on. Never had that prob again. Why couldn't the EPA leave them carbs alone-can't adjust nothing but the idle anymore.

kind of similar problem-not quite tho

i have a yerf 3203-tecumseh 6.5 and the other night the float got stuck and when i put gas in the tank-it just flooded the carb and leaked out the intake. I took the bowl off the bottom and wiggled the float and it freed up and moved smoothly. Put it back together and started it up-it held gas and drove for about 80 yards then died. took the bowl back off again and hosed everything down w/carb cleaner, but didnt take anything off-it was dark and i couldnt see what i was doin really and honestly-i dont know much about karts right yet so i didnt 100% know how to take the float off. i start the kart up and it immediatly cuts off. if im quick enuff to grab the throttle, and ease it up a lil bit, it may stay runnin for a second, then cut off-if i rev it up-it stalls.....maybe needle and seat need cleaning???

 

[slideways]

Cleaning the carb isnt a bad idea in any situation. The main cause for your problem is not having the bowl installed correctly. On these carbs there is a step in the bowl that allows the float to dip down into it. You have to have this mounted correctly or the float will not suck enough fuel over bumps and at full throttle .

Put the shallow end of the bowl nearest the needle/seat hinge. You can also make a slight float level adjustment by bending the tang on the float to allow more fuel in the bowl so it doesnt starve for fuel.

 

[LoRydeRanger]

thanks-i'll give that a shot sunday night when i get back into town-i never even thought about y they would have the bowl offset like that....stupid rookie mistake

 

[LoRydeRanger]

i actually got a chance to spin the bowl around this afternoon before i left and no change-its still starting and immediatly cutting off. If im quick enough w/the throttle i can keep it runnin for about 10-15 seconds but then it will cut off. Also if i crank it wide open it stalls and trys to cut off.....any suggestions
