Is this a common feature? Are we following the correct procedure? Shouldn't this work if we only push the button and do not advance the throttle? Let me know, and thanks.
Unless it's winter and the engine room of your boat is really cold you shouldn't need to use the cold-start lever or button or whatever you have.* On our boat the cold start controls on the injection pumps are connected with Teleflex cables*to pull-knobs on the instrument panel.* But we've never used them, and we've been advised by our diesel shop (and the FL120 operators manual) that we don't need them in our climate.* So far in twelve years we never have.** Were we in New England or Alaska it may be a different story come winter and the cold start knobs would become necessary.
The operator's manual for the FL120 does say to advance the throttle about a quarter of its travel if the engine is cold (normal ambient temperatures, not winter)*before pushing the start button.* If the engine is hot/warm the manual says no throttle advance is necessary.
I didn't advance the throttles at all when starting when we got the boat*but after reading the instructions in the manual (always the last thing you're supposed to do, right?), we've always put in a quarter throttle before starting and the engines start noticeably*quicker than they did with no throttle and a cold engine.*
The cold start control on the FL120 releases a stop or catch and allows the fuel control lever in the injection pump*to move farther than it normally does.* This is why the manual says to put in full throttle, then pull the cold start knob (or push the release on the injection pump).* If you don't put the throttle in its maximum postion before*pushing the cold -start release it won't actually do anything.* It needs the max throttle position in order to allow the fuel control lever to move farther.
The operators manual for the FL120 does a pretty good job of spelling out the correct*starting procedures for various conditions.* If you don't have a copy of the manual they have it on line on the Grand Banks owners forum.
