Thanks again everyone!
Good deal, glad you got it fixed!

It makes NO difference at all with respect to the ignition coils what speed the engine is at when you engage or disengage the blades.
It can make a difference with an electric clutch or your primary deck belt though what speed engine is at when bladed are engaged, but makes NO difference when blades are disengaged!

Typically, I would recommend turning the engine off at idle speed unless you get afterfire (backfire). In that case, you may have to play around with the throttle at different speeds to find a spot where there is minimal or no afterfire. If you just used the moer hard for a long period of time, idle it for a minute or two before shutdown.

I personally like to start ALL equipment at the slowest speed possible, especially when the engine is "cold". This is more easily done if you have a seperate choke control. But can be done if choke and throttle are in the same lever... As soon as the engine starts, I bring it to idle or just above to "warm up".

You don't get in a vehicle and run it up to 3600 RPM the second it starts, same thing here... Some people will have different views but those are mine.

Maybe taken out of context here, but it seems to me that asking a clutch to stop 'everything' at a lower RPM would extend its life as compared to disengaging at full throttle. Am I missing something here? Or, perhaps this only refers to electric clutches?

The only thing that would "wear" when you disengage blades with an electric clutch is the brake pads... When you disengage the blades, the clutch plates release and one plate then rubs on the brake pads to stop the blades.
I guess in theory, if you disengaged the blades at idle there would be less wear on the brake pads. Typically though, the plates will be worn to the point they will no longer engage or be slow to engage or have either bearing fail before there would be much issue with the brake pads.

The Op didn't know about proper blade engagement and disengagement, now he does. It doesn't really have anything to do with the coil, but it can be a domino affect. When you start to stress one part of a machine, it then stresses another, and another.

Everything has been cleared up. Jeff had given good advice to begin with.

Disengaging blades @ full throttle is harder on the clutch than engaging @ full throttle.

Oldtimer,

I would partly agree with that but as I said, a bearing failure or clutch plate wear will usually (not always, but usually) happen before the brake pads are a problem.

Great advice guys. I just started mowing last year when i got downsized at work. Anyways still trying to learn everything.
However, i have another question. My backpack blower started to give me trouble yesterday. Every time i give it throttle it seems to flood and stall. Now when its starts it dies right away.

thanks in advance!
