Ok so i hope this is a good place to put this topic.
I have been using for the past 3 months or more been pull starting my big bore engines with electric start and no pull start. This modification should be do-able for any engine with a metal shroud (my kohler won't work) so its not just briggs that this should work.
Over this time of pull starting them i kept breaking ropes. I have no idea why, i even used some super strong rope. So after thinking about what to do ( definitely not buying a battery lol) I realized why not do a recoiling one. I searched for the ones off snapper mowers and they are like 50 dollars for a used on. So what i did was buy a gx270 pull start off ebay for 13 dollars.
Here is what i got-http://www.ebay.com/itm/310417052838?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Now i had a old honda generator that didn't have a pull start on it but it did have the pull start cup. So i didn't have to buy one of those.
I proceded to put the cup on the fly wheel. If you do that you will notice the cup makes it sit up to high. So you have to cut it down, and make new grooves for the pull start.
I did that with a grinder, it was easy. You may have to cut your down more than mine so. After that it would sit on there like this
Now your gonna have to drill new holes for it. I drilled 6 holes in the shroud, with the pull start sitting down on it, and the fly wheel cup cut down it is centered. After that i bought 6 bolts ( I think 1/4in) And nyolock nuts from tractor supply.
Thats with the stock paint
Thats with it painted.
Now i didn't think of this first, so i'm not claiming I invented this. You can go see videos on youtube from this guy that did his. I'll make a video of me using it tomorrow.
