Hi folks,<br /><br />Been lookin through here all day... great forum!<br />Honda BF5AM BADS-1203337 5hp 4-stroke. Not positive of year, previous owner is pretty sure it's a '92. Older gent owned it, used it maybe a dozen times a year up until 2000. At the end of that season he had noticed a little oil slick on the water whenever he was sitting in one place for a minute or so with the motor running. Apparantly, it wasn't much, and it always ran fine, so he brought it in to the local Honda dealer and asked them to have a look at it. A week later they called and told him the engine was shot - cylinder was egg-shaped! He told them not to bother, that he'd live with it with the oil leak, but they refused to reassemble it unless he paid them $400. So he got it back in a box. Been sitting in his basement 'til I got my hands on it last week. Spent several hours cleaning it up and putting it back together - at least nothing was missing. Checked the bore with a telescopic gauge and if it's out-of-round, I can't tell... it looks just like new, no scoring or scuffs at all. Same with the crank, cam, the works, no obvious wear. But when I did a compression test, I only got 55psi. Few squirts of oil brought it up to 85psi. So looks like at the very least the rings are bad.(?) I'm just wondering, before I put any money into this thing, if the cylinder really is out, and I just can't tell. Could anyone with a manual give me a piston-to-bore clearance, or any other spec that might help me in determining if it's worth rebuilding? I don't mind spending money on it if the block is good, but buying rings, gaskets and a manual just to find out it's shot...ugh!<br />Any help would be greatly appreciated 
<br /><br />Thanks
