First of all, can someone tell me why B&S is no longer installing recoil starters on lawnmowers? At least on 17.5 HP and up models. This is very handy when you discover that the battery has bit the dust after the winter and you really need to mow your yard that particular day before going back to work the following day or you're like me and you're too cheap (or frustrated) to buy a new battery every other year.
When did Briggs and Stratton went from using nuts to bolts on the crankshaft/flywheel?
Reason I ask is I have this nutty idea to made a rope starter for one of my lawnmowers. Most likely my MTD 17.5 B&S engine. I also have a 21 hp B&S Husqvarna. I'd like to do both.
I have a 14hp B&S circa 2000 that threw a rod through the block. It looks like the rod bearing nuts were not properly torqued or had Locktite from the factory and vibrated loose which sent the rod through the block. The engine was less than 5 years old.
This engine is on a shelf in my storage building and I'm going to have to move some stuff to get to it and pull the cooling shroud off to find out.
The plan is to:
1) Drill a hole through the side of a socket and the crankshaft bolt for a roll pin or cotter pin.
2) Up through the socket will be a 1/2" carriage bolt threads facing upwards. Maybe a few flat washers to take up any slack in the depth of the socket.
3) Use a pulley that uses a square keystock to keep from spinning
4) Grind a slot in the end of the carriage bolt for the keystock.
5) Cut a groove at an angle for the knot on the end of a rope.
This winter I pulled my batteries off my mowers and hooked them to trickle chargers. Hoping I can get more than 1 to 2 years out of these horribly cheap lawnmower batteries everybody sells.
As long as I have the strength and ability to pull start a lawnmower engine, I'd just soon do that as to keep spending money on these junk batteries.
I think my Interstate battery made it one season. The Husky battery from Lowes (I think) made it 2 years before it bit the dust.
The battery on that same Snapper went bad after a year and I just pulled started it for 10 years until I sold it.
