W-O Carburetor and Fuel
« on: August 05, 2015, 12:42:50 PM »
Got my rig up and running after having to replace the fuel tank as the sprayed lining inside had deteriorated and I couldn't go for about a mile without having to replace the fuel filter. Needless to say it reeked havoc through the whole fuel delivery system. I replaced the old fuel tank with a new poly one (I'll post more about that later) and also replaced the old fuel pump as well. Whilst waiting for those parts to come in I cleaned out the carb as it turns out was also filled with debris. Once having everything replaced the engine now runs rich (more gasoline than usual). I think I've pinned this down to being the fault of the float in the carb as it was filled up with gas but also am not entirely sure if while cleaning the carb if I did not screw the fuel jets in properly.

If anyones got any idea or help on how to fix this let me know

ps. Also have done an oil change and am waiting on a new oil filter as well as a new float for the carb.

Scout pilot is the best, he knows all about these little buggers. He serviced my carb and fuel pump and it's beautiful

The adjustment to lean out the fuel is the large spring loaded screw on the front of the Carter.� A general starting point is to screw this all the way in (Only until it stops.� You can damage it if you screw it in too hard.)� Then screw it out two full turns.

To lean out the mixture, you open the screw a little at a time then wait a bit before making more adjustments.� While doing this, you may need to adjust the idle adjuster screw on the back side of the linkage.

The float level is also critical.� If your bowl is overflowing, you may need to adjust the float level, and or, the metering rod.

Here is the link to Scoutpilot's web site.� Very informative.� He describes these adjustments verbally, and with nice videos...

[size=12]A vacuum gauge and a dwell/tachometer are needed here. You need to know how much vacuum is being drawn at 600-700 RPM with no choke. Post that number here and we can go from there.[/size][/b]
Old fashioned service never goes out of style.
