Re: No low idle on Force 40
Glen,
Forget what you know about timing engines, it won't work here. The safest way to time these engines is using the starter motor, that's right, you won't time it running.
First, you have to see what kind of timing marks you have. These engines come with all kinds. Look on the vertical surface of the flywheel for the marks. Sometimes, you have a scale like a car and then other times you may have just two marks or four marks. Let us know what you have and we will tell you what is what.
The static timing for these engines is 32BTDC. I recommend using 30BTDC due to the makeup of the gasoline which is not the same as when the engine was built. Why chance detonation?
The tools needed for the job are:
1. A basic timing light. If you have the advance type, set the advance to zero.
2. A jumper wire to jumper the neutral safety switch so that you can turn the engine with the trottle at WOT
3. A push button remote starter switch.
The procedure is as follows:
Disconnect and remove the plugs. VERY IMPORTANT - ground plugs so you don't damage the CDI module.
Mark the timing marks with chalk so you can see them better. The fixed mark should be at six o'clock under the flywheel as you are looking at the engine.
Disconnect the fuel line if possible or turn off the fuel.
Hook up the safety switch jumper, solinoid jumper and timing light to the upper cylinder wire.
Move the trottle to WOT.
WARNING: DON'T WEAR LOOSE CLOTHING OR JEWELRY AROUND THE OPEN ENGINE.
NOTE: When looking at the timing marks, the furthest mark to your right will be TDC.
Engage the starter and aim the light and record the findings. For a starter run cycle, I use one minute on, five minutes off for the first two cycles. If you need more, increase the off interval to 15 minutes so you don't damage the starter.
For adjusting the timing, it would help if you could send me a couple of pics of both sides and the front of your engine. Manuals give lousy pictures.
