Re: Compression Test

Skyhigh,<br /><br />I would like to see the grouping a little closer, say within 5 to 10%.<br /><br />However, a simple decarb proccess may help.<br /><br />Do your spark plugs all look the same?

Re: Compression Test

skyhigh,<br /><br />Do the decarb, that may fix you right up.<br /><br />Do a search on this board for the decarb process.<br /><br />The decarb. agents are available at most any outboard dealer. they can also advise you on how to do it, with their product.
