Merc acting up
Took out my 40 Merc ELPTO for its trial run today. It ran okay. Ran it up
to full throttle, then about 300 yards later, it had symptoms of gas starvation. It has an in line filter, which I am changing tomorrow, then take it for a spin after that. It also is cranky at low rpms, needing the fast idle to start and run. Been sitting up for a while. Gas was emptied, and fresh gas put in this morning. Plenty of run time to burn out what was left in carbs. Checked connectors, and they are the Merc snap type. They LOOKED to be on there and snapped. New spark plugs. I imagine I'll take it to the shop and have it tuned, but any ideas what makes it lose power on high rpms? Will see if a new filter makes a difference. This one LOOKS clean, I mean, no dark color on the filter paper inside the see through filter. Steve |

Steve Could be the vent on the tank or the fuel pump isn't drawing right and you made it that far by priming the bulb on the line or could be the line itself. |

Is the cap on the tank tight? Did you pump the primer bulb to "Firm" before
starting? "SteveB" wrote in message ... Took out my 40 Merc ELPTO for its trial run today. It ran okay. Ran it up to full throttle, then about 300 yards later, it had symptoms of gas starvation.

The carb needed a thorough cleaning. A bad stator could also affect the higher RPM's but save that for last - they are big bucks. -dk |
