It would probably help if you were a little more descriptive.

We did a compression check and we have 105/110 at each cylinders.Next thing to check is sheared key at flywheel

Re: 90 hp motor will not start

You need several things for an engine to run.<br /><br />1. Compression-you have that.<br /><br />2. Spark, at the right time.<br /><br />3. Fuel.<br /><br />One, or more is missing.<br /><br />Being intimately familiar, with that engine, check these.<br /><br />1. Fuse, near starter solonoid.<br /><br />2. Kill switch lanyard.<br /><br />Let us know.
