Motor runs fine in idle, when put into gear rpm's only seem to go about half as high as when at idle. Good steady and strong spark on both plugs. recently rebuilt carb. thanks in advance.<br /><br /> --John

Welcome to Iboats, satterly! If you want to fix up one of your posts, just click the "Edit Post" icon.<br /><br />Make sure both sparks can jump about a 3/8" gap. There's a common problem where they'll jump a spark plug gap just fine (nice & hot) but not a wider one. Also, closely examine the spark plug wires for any cracks, etc.<br /><br />If that all checks out, try pumping the primer bulb. Does it make it run better/worse/no different?<br /><br />Revving the engine in neutral is really bad for it.

Make sure your throttle linkage and spark advance can cycle completely, when in gear.
