1986 force 125 question

[bayarealiner]

when cruising for a few minutes, it starts to cough just a little bit, and if I don't go down to idle for a few minutes she'll cut out completely. Im gonna be rebuilding carbs and decrbing the cilynders soon, but I still want to know whats going on.<br /><br />Thanks in advance.

Sounds like it is starving for fuel on one or more cylinders.<br />Not good. Running lean means running hot, and Force motors don't last long if overheated.<br /><br />Could be carbs, or a weak fuel pump, or an air leak in the fuel line.<br /><br />I would do the carbs, put a new diaphram in the fuel pump, buy a new fuel line and bulb, and replace the fuel lines to the carbs.<br /><br />The parts are cheap and it beats ruining and replacing the engine.

Thanks for the info.<br />Why fuel lines and bulb?<br />I didn't plan on installing a new fuel diaphragm, but that sounds like a good idea.

If original, they are 19 years old, time to replace them. Rubber/plastic hoses crack, rot, can leak, can allow air to be sucked in. Bulb has a check valve in it, which can go bad. <br /><br />As long as you are overhauling the fuel system, why not do it all and eliminate all possible trouble spots, and save yourself from a future fuel system failure.
