Yes Norm, Briggs should have fixed all the motors for free ,but not likely ,heard of a few breaking at 20 hours use,
so not great for Briggs and now people refer to them as Breaks and scrap em.
This good decomp fix can at least stop the motors getting thrown out.
I did hear that in 2020 Briggs redesigned the ACR on the cam but I haven't heard how reliable the new
cams are.
Big problem for me now is I am out of oxy and there are some jobs I can't do without oxy
Yes I have the same problem ,the last bottles I had were dirt cheap second hand ,you do see them for sale
on market place from time to time.
Another option is to get the bottles filled but is $200. for small D bottles.
I've been using the LPG torch more instead of the oxy kit for heating and lead /soldering etc.
I thought possibly another type of oxygen less pure than what's normally used would work but it won't work,
the only thing I've found that may work cheaply is pure oxygen for a scuba tank but it's not legal to do ,but
could be possible to use and only around $5 to fill a D sized bottle.
The scuba tank with LPG would be cheap for brazing and cutting.
