Quick update!

I gave it a shot of fresh fuel in the tank, laced the spray to it while starting and I got it to catch after a couple of tries. It still wasn't terribly happy at first but it went and that's good enough to ease my mind a little (for now), I also ordered a pair of Champion J19LM plugs for it (a few bucks cheaper than the RJs) and will pop them in as soon as they arrive which should be tomorrow!

Look up
Autolite Iridium Lawn & Garden Spark Plug
I have been Super happy with them in my briggs opposed.

Quick question.  Does your model have the aluminum or fibre nose cone?  I thought I saw you say aluminum?  I assumed that ony the ones with the lights on bottom were the aluminum ones.

Champion J19LM crosses into Autolite 458. I will order them on my next paycheck and give them a go, can't ever hurt to have spares anyhow and we had good luck with Autolites in my friends race car, thanks for the tip!

Well would you look at that... I just went outside and scratched the nose cone and it IS fiber! Sounded solid like aluminum when I tapped it before! Geeze I'm embarrassed! Lol. The lower half of the grille is definitely aluminum though, is that normal?

I love the irridum plugs.  Yep, that is totally normal with the nose cone on these.

This is the only one that I know of that is cast aluminum. Note the lights are in the middle not the top like ours.

Man that thing looks a fugly with the headlights down low don't you think!? Lol.


Another quick update:

The Champion J19LMs arrived today while I was at work and have been sitting outside so they're just as cold as everything else (just below freezing like the other day), I gapped them to 0.35", popped them in and wouldn't you know it the tractor fired up and was more manageable to keep running for it to warm up a bit and fully catch. Not perfect but much better so I think once I solve the difference in cylinder pressures it shouldn't be a problem anymore.

The plugs that came with it were NGK BR6S which, aren't even in the proper heat range for this engine (too cold) or a listed cross reference for it either... regardless of that I've never had good luck with NGKs in B&S engines and they were going to be ousted at some point even if they did work half decently.

Question for you all... does anyone have any experience with these pen style spark testers?1980 Roper 16T  - Page 2 20221134


I forgot about it and just tried it tonight for the first time (only on the Roper) and find that the light is quite dim, there'd be no chance of seeing it in the daylight so was hoping someone here has a little feedback on that?

@Brianator that grill style grows on you over time.

Not familiar with that pen style spark tester.

It possible the valves on the one side be carbon build up?  If so, the better plug may self clean it giving it the onions some.  May also need to check valve clearance. (that sux on these engines as you have to pop the head off).  Like I mentioned 70 is still great for these, but a 30psi difference is quite a bit.

I dunno, 70psi seems pretty weak to me for any engine and yes 30psi difference is HUGE! 5-10% difference is not a real concern but 30%... not liking it! Lol.

I should be able to check the valve clearances by popping the breather covers off which are on top under the air cleaner no? I figured it would have a similar setup to a single slug L head in that way, there has to be a way to actually measure it when it's fully assembled.

It's very possible the valve(s)/head(s)/piston(s) are carboned up and causing that ruckus in which case a Seafoam treatment or 2 should help but I really need to check the valve clearances first.

What I really need to do is forget about it until after the Build Off but it's bugging me! Lol.


*EDIT* When I've been speaking of valve clearance I've been meaning about the valve STEM clearance which I know can grow loose or tight over time, I believe @MightyRaze is speaking of valve-head-clearence in which case yes I suppose I would have to remove the head unless I could get creative with perhaps some solder?

No I was talking about under the breathers.  To resolve any clearance with some grinding stems or new valves.  That's what I was talking about taking the head off.  I know you know all that.   Very Happy

Fair enough!

I do have the proper B&S valve spring compressor and the original 11hp flathead from The Warhorse that I'm planning on trying some sneakiness on to see of it's at all possible to do some valve tip filing and polishing without removing the head. I might as well try and find out, that engine probably needs to be torn back down to get to the bottom of whatever is going on as it is!

It is nice to have a proper spring compressor.  Makes the job so much easier.
