My turn to have this issue now.
4LB1 33hp.
Solenoid part no. MV1-77 897209-1140
My stop button is taking longer and longer to stop the engine. Having read this thread, I guess the first thing to do is take some WD40 and a hammer to it.
If it fails completely, are there any updates to the comments already made? Engines Plus don’t have the part listed so I’ve emailed them and am waiting for a reply. There are some listings on eBay that say they will replace a solenoid in a 4LB1, but the part no. they list as replacing is not the same as mine, so I doubt they will work.
I’d be grateful for any suggestions including how you go about installing a manual engine stop.
Thanks, Kathy
