I have a 92 Mercury 150 XR4 BlackMax. One of the POs installed a hot foot and apparently disconnected the fast idle lever and choke. Or at least that is what it seems like to me. I know the fast idle lever does not work.
When I try to start the engine, it's sometimes hard to start and won't fire without pushing the pedal down a little. Once it does start, it idles really low like down around 400 RPM. It will also sputter out and die idling that low. I can give it a little gas to keep the RPMs up a little, but even then it's like it bogs down and dies. It even does this after the engine has been stopped for only about 20-30 minutes. I have to start it 5+ times to get it going.
Once the engine has been run, it will idle fine at around 800 RPM or so, but the engine has to be run to get it to do that. I can give it more gas when out of gear (if it doesn't bog down and die first) to get the RPMs over 1000 for a little while and then it's somewhat OK.
I'm guessing I need to rebuild the carbs. But figured I would ask here first. I'd really prefer to wait until winter to rebuild the carbs if possible. I know when pull starting, there is supposed to be an enrichment button pushed in (same as choke I assume). Any clue where that button is? I might have to see if I can figure out if the starter's choke is still connected or not for sure.
