pull away problems when warm
I have a 200hp Suzuki O/B with 3 Mikuni carburettors; all was well
until a recent service. Now o/b starts perfectly and first run will go superb, when we stop to change over skier/driver, typically 5 min or so stop, that is when problem occurs. The motor restarts OK, but when you engage gear still OK, but as you open throttle the engine does not pick up, and usually stalls. The simplest way is to recover seems to be: a) engage gear and idle away at low speed for a minute or so, engine then gets to a point where it sounds less lumpy, and it will then run OK .... A quick 30sec run around and it will be OK to then return to skier and do an immediate deep water start with no problems. (i.e. no powering off engine) b) start engine, and use fast idle lever to increase idle speed to about 3.5 to 4k revs, do this for about 20 secs ... and again it will clear and run OK. This seems to me be something like choking up due to mixture incorrect ..... But why would the first run go so well? Anybody any ideas? .... I will be taking it back to service agent, but be good to have some ideas. Rick |
