How does one clearance a connecting rod? I've seen some talk over at 4cycle about clearance on a predator 212 rod being too tight and seizing up at high rpm. The consensus seems to be that the ideal clearance between the rod and crank is. 0025.

So I made a few changes to my cart. The one that is giving me trouble is switching from a 64t to 54t sprocket. I did not think it through but when I put it on the chain is now too long. Well I got around that problem by using an idler pulley that's on my kart. Problem is this pulley has a loose...

Well I just saw a CL ad for a '80 CB750K motor(and bike if I want it). I want to put it on the frame below. Is there anything I need to know beforehand(a guide to hooking it up if there is one)? Any warnings? I've contacted the guy and he says that he bought it as a parts bike(off the frame)...

What and where would you buy? Engine is for a non-racing kart, some off road mostly asphalt though. Speed is end goal. Right now the motor is bone stock except governor removed and kill switch added.

I have a 212 Pred on a Murray frame. I don't know what model it is, but we've had it a couple years after we bought it from someone. Today I changed the driven tire(that was a pain in the butt!) with a new turf tire. I filled it then let out some air for increased traction. It does bite a...

My first question is how tight is the screw on that holds the clutch assembly to the engine shaft? It seems if I crank it on, the clutch never disengages(tries to roll on idle) and if it is loosened just a bit then the kart will idle with no issues. Also, I've read that the Predators(212)...

I picked up a Predator 212 today from Harbor Freight. I'm going to use it to replace a 6.5hp Tecumseh on a go kart. I can't start the thing though! I checked the oil and there was some in it(looked to be full by the dip stick). I put some gas in it, turned on the engine, turned on the fuel...

How taught should the chain be on the sprockets? I'm using a centrifugal clutch with a tecumseh 6.5hp OHH60.

Well I'm finally going to do something with an old Murray offroad(I think, it has a roll cage) cart we have. Not sure of the year, but it carries a 6.0HP Tecumseh OHH60 71106C engine. I want to up the power a little. Where to buy parts? Right now it leaks gas out of the little silver bowl on the...
