40 hp Force starting problem?

I've got a 40 hp force thats about a 94 model, and It is very hard to start cold and it dosen't want to idle. The only way to start it is to use my hand to choke the carb and then have to keep it idled up until it will run. Any help on how to repair the choke would be nice.

What model number is your motor? What seems to be the problem with the choke? Is it not fully closing or closing at all? Are all the parts intact to the choke? Are you missing parts to choke or does it just need adjusting? Are you pushing in key as you try to start motor, which then activates choke? Do you know proper starting procedures?

pump bulb till hard
put remote control in neutral
advance throttle forward, This should be about half way forward, there should be a tab of sort that does not allow throttle to advance all the way forward in neutral to protect engine.
Push in key (should hear a clicking sound) and turn key.
After starting leave throttle forward till engine warms up. Tach should read about 1500 RPM's while warming up
After warming up you can pull back on throttle to idle position

We NEED the model number and serial number to determine the year. Different systems from year to year. Newer models did not have a choke, but used a fuel enrichment valve instead.

Re: 40 hp Force starting problem?

Open fuel tank vent

Check the kill switch, place in "run" position

Squeeze fuel primer bulb till firm.

Advance the throttle 3/4 way, without putting it in gear. -- This is done by either pushing a button in the center of the controls, or pulling the shift handle toward the driver, or raising the fast idle lever, all depending on what control unit you have.

Activate the choke (fuel enrichment valve) by pushing in on the key. The valve is only open while the key is being pushed in.

Turn the key to start while continuing to hold the key in.

Release the key and choke when it starts.

3-5 seconds of "choke", is usually enough.

Be ready to pull the throttle back toward the idle/neutral position, when the engine starts and the revs increase.

Continue to pull the throttle back as the engine warms up.

You should not have to use the choke much, if at all, once the engine has warmed up.

Engine should start within 10 seconds of turning the key.

Sorry for the delay in getting back to ya'll but I work 12 hour shifts at night and only have time to work on my boat on off days. Anyways I found all kinds of numbers and I'm not sure which ones I need. Here is what I have found. The carb is a Tillotson and has 2 numbers on it, WB117A404 is on 1 side and 826043 is on the other side. On top of the motor near the back is a number R576973 and under that is 4 068. On the side of the motor is a number 800 and under it is 81815202. I don't know if any of these are the model numbers or not but as of right now I didn't see any others. I did look at the carb and I am thinking it does not have a traditonal choke from what I can tell. Thanks for the info.
