I just bought a new Redcat 70 ATV for my daughter. It runs great until she is sitting on an incline it will barely pull uphill from a stop. It is fully automatic and I checked several things. Can't figure out the problem. She weighs 60 pounds so it should pull her no problem. Any ideas other than carb adjust, removing restrictor from exhaust, change oil, regap plug. not sure what else I have tried.

Thanks,
Mike

 

Redcat has an 11 tooth front sproket on their website if your 70 has a 14 tooth on it changing it to the 11 would give it a lot more bottom end which would help on the inclines but would hurt on the top speed

 

I thought about changing the gear, but I don't think it should be necessary unless this quad is really weak. That is what I am not sure of.

 

I can not believe that this atv is not capable of pulling 60 pounds uphill. My nephew has a Manco 90cc fully auto and it hauls me around no problem. And I am 6'4" 280.

If it will not pull my daughter, it would not pull anyone basically.

 

does it start cutting out or what

 

I bought my son a redcat 90 and me and mt dad had to open up the carb and clean the whole thing I could not have done it but he is pretty sharp anyhow I am pretty sure that the jet is the deal that has a bunch of needle sized holes in it and gas shoots out them holes regardless of what it is called my dad cleaned each on of those holes and the thing had a lot more power after that my son hasn't rode it yet but it pulled me up a hill pretty easy and I weigh 160

 

It does not cut out. The engine rpms go up (not nearly all the way, though) but it just sits there like the clutch is slipping or something. If you take the weight off of it, it goes uphill. It runs great on level or downgrade.

 

if it don't have the power I say go with the 11 tooth sproket as soon as my son gets used to riding I will put the 11 on his I more thing to try would be hold the choke in if it goes up hill then you no it ain't getting enough gas

 

Have you adjusted the restrictor screw out on the throttle?

 

The restrictor screw was not even installed. the throttle is not restricted. If you lift the back wheels off of the ground, it screams. Just no power. Actually I think the clutch is wasted. I took the carb off and apart. It was clean. A compression test showed about 100 (with an old tester) but it starts right up and runs great on flat ground so I think the engine/carb is fine.

Is there a way to adjust the clutch? I saw a few little pieces of what looked like it could be clutch or gasket material when I changed oil.
