You must remove the engine cover (three torx screws) then you can pull the line off the plastic bulb disk and remove it from the cover by pushing the side clips.
Put silicone on the bulb disk and force the bulb on to the disk. I had to use a vice to hold the disk, it is a very tight fit. When you get the bulb on the disk, reinstall it in the engine cover and reattach the hoses. The gas tank hose will probably need to be pushed on to the carberator and the gas tank also. This is hard work but is the only way you can instal the bulb.

My lawnboy silver series is not getting any spark

If you are getting no fire it is going to either be your coil is grounding out through the kill wire somewhere or your coil has gone bad. Try unhooking your kill / ground wire directly from the coil then check for fire. If you still have no fire then you will need to replace the coil. Hope this helps.

Have a self-starting, self propelled toro lawn mower about 5 years old, I ran it out of gas by accident & now it won't start

It seems to be an obstruction in your fuel delivery system. Get a can of ether and a spray a short burst of it into the breather area near the carburetor, if the mower starts up and then stalls out, then you may need to get your carburetor serviced.

Lawnboy 10665 won't self-propel and impossible to push

If you have the smell of rubber burning the belt isn't gripping. Make sure that there isn't anything stopping the wheels turning like old grass or even a piece of twig. If their clear try adjusting the tension on the drive pully.

Carburator issue. If you have some mechanical abilty you can pull the carb off else take it to a shop. You probably left gas in it off season. Either the main jet is clogged or the float valve is stuck. Either way, remove the carb, tae off the bottom cover and clean everything out with gum out or a carb cleaner. reassemble and eveything should be fine.

Maybe the engine is running with the fuel from the primer bulb (about few seconds), the carburator is not working and need to be removed checked and cleaned, the most common fail is a jet clogged.

LawnBoy Silver Series 6.5hp (manual start) self-propelled. Spark Plug does not have spark. Took plug out, clamped brake bar and held plug on engine for ground in plug boot. What can I do to get spark back?...

Disconnect small wire at ignition module. Then check for spark. If no spark, replace ignition module. If there is spark, then there is a short in the kill wire or engine control cable is not adjusted correctly.

Rerunning the belt on an o6 self-propelled Lawnboy

You may have to loosen the adjustment a bit to let the transmission tilt farther forward. Do not loosen the other nut on the adjustment, that way you will know how far to re-tighten the one you loosened when you have the belt on.
