Hello all. Newbie here. I got this mini buggy on a trade and I'm having for issues with it. It has a yonghe 150cc motor in it. Not sure of the buggy maker as all identifying tags are gone. 1. When I get the engine started, it won't stay started. I adjusted the idle screw and fix that issue but...

Ok some i found some sprockets with a unihub that will fit my axle. The biggers sprockets only use a #35 chain so that would mean I would have to go with a 12t clutch for a #35 chain. What size rear sprocket should I get to give me the better ratio. 18 inch tires on the rear.

Ok so here is the sprocket I have on there now, 60t. Is there a sprocket like this one with more teeth? If not, how do I mount a new sprocket in the axle with nothing to bolt to? I'm a n00b here so forgive my stupidy. Is a 71t sprocket with a 10t clutch going to give me enough of a lower gear ratio?

Ok how small of tires will I need to go down to or how far should I gear down? I'd like to keep the tires but I think that may be the easier of the 2.

Also, should have a lil slake in the chain or should I raise the motor and tighten the chain?

Yes it's opening up fully for sure. I can't put the choke all the way to fast because it dies and I'm having to keep it about half to keep it running. I'm having trouble finding the adjustment for it.

i thought i did in the first post, clutch is a #41 10t, drive is 60t and 18 1/2 inch rear tires. :)

I just bought the clutch new at oreillys.

Just got my kart going, have some issues. *updated with pics* Ok so here's my setup. I believe the frame is a 2 seater yerfdog. Subaru Ex21 7hp Clutch is a 10t #41 3/4 bore Rear sprocket is a 60t #40 chain 18 1/2 inch rear tires So got everything on. Got on to ride. It's slow starting off...

How much guys?

Looking to buy a complete kart engine. 7hp or above. The kart it's going on has a 60t axle sprocket, 18 1/2 inch real wheels. I live in Missouri. Not looking for top of the line. Thanks

Awesome advice guys. I wasn't sure if I needed a sprocket or clutch but now I know. I'll be driving on mostly gravel and grass so more off roading than anything. Is there anything special I need to do after I remove the governor or just take it off and go? Thanks guys, awesome forum.

Also, what chain should I use? Should I change the axle sprocket. i want the most out of this motor!!
