In Reply to: Trouble with sleeves posted by Ethan Chamberlain on October 10, 2010 at 15:34:04:
You should get the piston out of the sleeve first before pulling the sleeve, then use a sleeve puller. How are you trying to get the sleeve out with the piston in? If you are trying to pound it out from the connecting rod side, you're probably going to mess up the piston, and will be difficult to apply force on center. Hitting it off center is probably what is making the sleeve stick, but it's surprising you've gotten it out as far as you did. Is the crankshaft still in the block? If you get the sleeve out of the block with the piston still stuck in it, how are you going to press out the piston without crushing/distorting the sleeve?
I would suggest buying some Iron Etch from NAPA (made by Martin Seynour Paint,) it's an acid that is used for cleaning sheet metal prior to priming. Pour about 1/2" in the cylinder and let it sit overnight, then drive out the piston with a chuck of oak and a big hammer the next day. I unstuck two W9 pistons and several other motors that way. Then you can get a sleeve puller to pull it out.
Be carefull what you do, since new sleeves and pistons for the 9 series are very expensive. You may be best off to leave the sleeves in the block and take it to a machine shop to have liners installed, depending on how the sleeves look.

But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
