no power

[linda1965]

got a new problem here: 1980s mercruis 470.<br />-hard to start, seems very low idle and barely running. Put it in gear and stalls. Sounds like a miss as it shakes and shimmies.<br />-at mid speeds runs great!<br />-give her full throttle and bogs down, sputters, as if not getting gas or no spark.<br />-occasionally and mid speeds while running great, she'll sound as if running out of gas and ready to die, then suddenly back to normal?<br /><br />I shall try new pluds and wires. I hpoe this rookie is on the right track.<br /> <br />Any ideas? Me wife's gonna kill me!

Re: no power

When was the last time it had a complete tuneup. You know, points, condenser, cap, rotor, sparkplugs, dwell set, timing reset, advance timing checked, carb mixture and idle speed set, a proper compression test, fuel filters, etc. You know, the normal yearly tuneup in the spring type thing.

Re: no power

When was the last time it had a regular tune?<br /><br />Plugs, points/condenser, fuel filter. Be maticulous with the point gap (use a dwell meter if at all possible) and timing.<br /><br />Do that first, then repost if it's still missing.<br /><br />That is, as usual, my 2cents worth <br /><br />Oh, and welcome to iboats!!!!!!<br /><br />Edit: Didn't see your post Don, sorry.<br /><br />Aldo
