Hello, I have a metal ball left over from the rebuilding. Should this go in the

clutch sprocket area? Gas leaking out air filter-Engine noise when rolling-

sounds like piston could be hitting spark plug? Engine has been sitting for

about a year now apart. Been a while since I've been to this site. Having

trouble figuring out how to get to the subjects sections of this site. I want

to look up clutches or gas leaks how do I get to this part of the site?

Like to get the engine ready for the summer. Thanks, David

There's an 8MM ball bearing in the drive train. Here's a schematic from Birddog's store. Part24 Your clutch will not disengage without it.

Thank you, Mickey!
That is the area I was refering to in my question. The ball goes in back of the pin in the small sprocket hole. (Middle of sprocket) The clutch was not working. I'll work on that and see if I can get that problem eliminated. The gas leak seems to be an old thing. I just don't remember what the cure is. The ping I hear in the engine is not a noise to hear after rebuilding. Thanks for the help! David

8mm ball

I took off the drive gear cover and took out the pin #26 and put the ball in

back of the pin and the gear cover does not go back on. Looks as it the ball

needs to be counter sunk. I'm looking at the speck sheet you included and

it looks like part # 20, needs to be disengaged some how to let the ball fall

in

just a bit more. Could be I don't know what I'm taking about too. All I know

is something needs to move to get this ball down just a tit more. I took the

spark plug out and the engine turns over smooth. I put the plug in and I get

the light ping noise. Sure would hate to bust that piston head again. Now

that I've have this beast apart once I have a good idea how to do it a

second time.

Could it be that you adjusted the clutch without the ball in place and now that you have put the ball into place, the settings should be backed off to allow room for ball?
As for the plug problem, I would take a bit of "sillyputty" and mould a bit of it around the tip of the plug. That way if the piston is touching, you would see the mark left in the putty.You could even go with some bubble-gum.

clutch pin and 8mm ball sticks out 1/8 in to much

Thank you for the comments. I have all gaskets on the engine. What I want

to do first is get the drive gear cover back on. The pin and 8mm ball are

about an 1/8 on an inch to long to get the cover closed. This means I need

to adjust (move) the clutch assembly away from the cover. What do I have

to do to get this done? Do I have to go into the gear side and pull every

thing out? And pull everything out to do what. What part really needs to be

moved the 1/8 of an inch. I've got a big hammer!!!

Do what cooltoy said, and that will solve your problem, i had the same problem as you and figured it out on my own. Take the tool that came with the kit and turn your funky lookin clutch screw until the cover goes on.

Thank you for the info. The reason I didn't follow Cooltoy's advise is I am not

sure how to adjust the clutch. I thought to adjust the clutch was on top of

the clutch pad is a adjuster that screws on and has little noches on top and

the small philip screw keeps this adjuster from moving. you are saying to

take this clutch pad (disk) off and there is a nut that is turned with the pull

tool that came with the engine. I tried a search for clutch adjustment and

found none. I did key in 8mm ball and found some info about the ball. If I

had it figured out I'd no reason to write this message. Thank you, David
