Oil questions...

[bwalker]

that's just it. it misses. if it ran i wouldnt mess with it at all.

Thats very strange. You must have something going on thats causing the sprakplugs to go bad like that.
How do they look when you pull them? Perhaps its running rich?

just mix your gas 50/50 with drain oil. that way you can use it in both tanks

Mostly Champion Spark Plugs, resistor type gave problems
About 10~12 years ago, I started having miss fire/skipping issues with Briggs powered mowers and Champion plugs.
Hard starting also. meaning several pulls . Typically my mowers start on the first or second pull after dry winter storage.
Always one pull afterwards for the summer. Shut off the fuel valve and let the mower run out the carburetor and quit after each use. Open valve as you get the mower out and by the time you get ready to go, the carb will be filled.

Air filters clean. Oil level good and clean. Fuel filters (yes I run inline filters and a cut-off valve in my push mowers) fresh non ethanol fuel. no chaffed wiring, loose controls or grounding clips etc..
Fuel jugs are kept indoors and spouts are usually covered. Never left out in the weather. No trash or water in them.
I'm a little picky that way.

A visual inspection of mower revealed nothing. Pulled spark plug and held to engine block and normal rope pull got a weak, intermittent spark.
Switching to the clip on test plug and saw spark looked fine.
Checked gap on all plugs, new and used.
Grabbed a new resistor plug and did the rope pull and looked at spark. Spark looked fine with a new plug.

Decided to grab the multi-meter and check resistance of old and new plugs.
I can't recall the specific numbers but plug from mower showed resistance of more than double of a new plug.
Same type and possibly came from same batch, as they were all bought together.
Bought some new ones and had exact same problems.
Have had a few NGK resistor type fail to high resistance also. Hard starting was usually the first sign.

I had to go round and round with the parts counter guy to get a Non-Resister spark plug. But worth the aggravation.

Running non-resistor plugs ever since and have had no more issues.
All of the resistor plugs got tossed in the trash after a couple seasons of no issues with non-resistor plugs.

sometimes they look perfectly fine. sometimes they look like its been running rich. i think i need to open up the exhaust. i dont think it flows good enough. that is my next upgrade is a header to see if that helps with the rich condition. i understand when they are sooted up why they dont work right. but when the are brown and dry and they still fail i dont get it at all.

I always look for any signs of the spark having a pathway down the insulator.
On some of the ones that failed, I bent the ground strap outwards away from the center electrode. Gives a gap of around .180 to .200 of an inch.
Then do the spark check again with the plug against the engine block. Figured that would help reveal a track/path on the insulator with the large gap now.
Never really saw a definitive track though. Spark jump was fairly random spots.
I only ran the first one that failed to the pint of letting it get a little sooty, before swapping it out. Finish the yard mentality.
After finding the high resistance issues, I swapped a new one (from my spare parts shelf) and went on. Until I had a chance to track down the non-resistors.

Cylinder fins clean and unobstructed. Shrouds are all in place and undamaged, with proper fasteners in place.
No accessories in the air pathway. Flywheel intact no missing fins.
I checked the flywheel keys, clearance to ignition module. No engine knock when in use.
Wasn't overloading the mower. Blades get visual at every use. Any dullness or damage and the blade gets filed and static balanced.
Always pick up sticks look for mole and ant hills before mowing.
That's when you spot the damned Yellow Jacket holes (usually) rather than stepping in them later.

I really wanted to know what was going on with the plugs.
But I never found an answer to cause it, just the resistor going high.

So I'm running a mtronic 462 at 40:1 is there a point where the system would get thrown off from to much oil? Can I do 32:1? Amsoil dominator is what I'm running right now.

Again I do not engage in that kind of language or WANT it anywhere on here but I also realize that some of you don't have a problem with it and it's going to happen which I can tolerate no problem in the off topic hang out threads. But in a constructive thread that some kid may be scrolling in the future looking for helpful information? That I have a problem with. As a side note I work with people daily that use bad language constantly and I don't have a problem with it as long as it's just adults around.

Thanks! Although I have no interest right now. I just joined and haven't been around very long, maybe in a couple years if there's a need.

Kids don't frequent forums... If words get you that spun up I would probably refrain from the internet, but thats just me.

Y'all are hopeless .
I don't have a problem, I hope people viewing don't either.
