Compression tested great last year or so ago, and I haven't messed with it since it last failed to start last year.... But still no kick with the starter fluid I hate using.

I haven't used starter fluid in years..my friend tells me its not the same as it was back when I last used the stuff...did they change it?

Gopher , the opposed twin briggs has only one twin lead magneto to fire both plugs and it does have points to fire the mag . At least the cub cadet opposed twins do....

 

Casey , the first thing I would check is the shearkey on the flywheel , I've seen occasions where they are sheared about halfway thru and they will give a weak spark

Been there and checked that flywheel key. I have been all under that shroud and flywheel and no points exist that I ever saw.

Now I'm going by my 582 cub cadet opposed twins ......if it has points like the cubs they will be on top of the engine between the carb and flywheel . They are easy to miss. you almost have to take the carb off to get the points cover off

Looks like there's 2 different styles of Magnetron coils used

Composite style armature

Armature with Magnetron module

 

Which one you have?

Ok , you got me wondering about the points on a opposed twin , so I walked out to the garage to check the three opposed twin blocks that I have sitting on the shelf . Two of the three have the points setup , but one that I have and evidently isn't a cub engine doesn't have the points provision . So I guess there was a change sometime during their production , making my previous posts about points  pretty much moot .

Can you take a picture of these points setup. Even if it doesn't help me convert mine it might help someone else looking for them.

Ok, just walked out there and definitely don't have that points cover on the one I am messing with, but I have a earlier GTV 18 I was given for free that is sporting one of those covers, and I may be taking a close look at it for either using all the sheet metal from the parts GT 18 machine to make it run and drive.... Hmmm... Or might need its engine for the Caterpillar... Lol.

Ps, the gtv18 I got free was advertised as needs gas tank, and I would say fender pan, seat, and the hood to open, as well as steering work lol.
