Well maintained ef 5000 YAmaha generator reluctant starter in cold weather. Must warm'er up before she'll fire up on her own. Inherited the unit; no manual. Am I looking at an automatic choke issue or have I hurt the 5000's feelings with my dark mutterings and thinly veiled threats? Lenny Hoy Greenwood Maine

SOURCE: firing order for a 1996 EF ford falcon

EF & EL are 1,5,3,6,2,4
EF has a coil pack under the inlet manifold the EL has a distributor
EF uses a waste spark system so 2 plugs are fired at the same time eg 1 & 6 - 2 & 5 - 3 & 4

SOURCE: Wont start when weather is cold.

Tune up... its flooding when its cold due to the plugs being worn out...

SOURCE: I need a manual for the 5000 generator.

Go to www.colemanpowermate.com, click on portable generators,click on manuals at top of page.

you will need to know the exact model #, look on black plastic cover on the back of the generator.

SOURCE: Hello, I'm trying to get an old Coleman Maxa 5000

First make sure you have fresh gas in the tank, as old gas can cause a 'no run' condition. Once you have fresh gas in the tank, make sure the gas flows freely all the way to the carb by removing the fuel hose from the carb inlet & checking for good flow (bad shut-off valve or obstructed hose by debris could cause same problem). Once you are sure that good, fresh gas is going into the carb w/o obstruction, remove the lower bowl from the carb - carefully - do not lose ANY parts, starting with the washer on the bolt. With fuel flow 'ON', fuel should flow freely when this bowl is removed, so shut off fuel valve in the hose. Now, if you carefully remove the bolt / brass tube from the center of this bowl area (center of plastic float) - remove bolt downward, like you would a lightbulb from the ceiling - this bolt should have several holes in the side, they are probably clogged, so unclog them with a needle or wire, wipe clean, and reinstall. That probably just solved all your problem.... if not, you likely will want to replace the carb completely, as it is not very expensive, and will surely solve your problem. *** Be careful with gas fumes !!! ***
