I've been running a set of these for 4-5 years.. not because it's my plug of choice, but it was what the local FLAPS had on hand. I've heard the electrodes can break off and bounce around the cylinder though. I figured I'd change them out next plug change, but they haven't been out of the engine since I put them in. |

| Your right I did miss that reply earlier. The backfire is mainly coming out the right side exhaust. After tinkering a bit and letting it idle I felt the dual exhaust and the passenger side was putting out a significant less bit of exhaust than driver's side. Spark plugs were black as can be and have never even seen a load yet only tuning in the garage. I took the linkage off the right side and opened the idle set screw a half turn them out the linkage back on and it made a significant difference. Is it possible if one carb is running too rich it will bleed over to the other one via the balance tube? |

Yes.
That backfiring out the exhaust is when the mixture is too rick. Popping out the carb is too lean.
Black sooty plugs is too rich.
When I trouble shoot cars I always start with basics. Valve adjust and oil change.
warm it up and do a compression check.
From that point I move forwards based off of that information.

How many thousands of miles would you consider to be "quickly?" |
I regularly saw failures at 3,000-5,000 miles ( Which was about 1,000 miles more than a fu*%ing Split-Fire.) in CIS,CIS-E, Digifant, & Motronic equipped watercooled cars & determined that the "cheap" copper core plugs were best for these applications which run much leaner than the aircooled cars. If you just have to piss your money away on platinum plugs, I would suggest NGK.
Maybe I just experienced a "bad batch" over a 15-20 span, I will say that I will never again use a Bosch platinum spark plug for anything other than temporarily plugging a vacuum leak.

Ive never fouled one. perhaps there were deeper issues with your exp....some things cant be fixed. air cooled has nothing at all to do with fouling plugs... the ones in my bug probably have over 100000 miles on them..as this set were in my 1874 before the 2028. |

This wasn't on my car, these were about 200-300 customer's cars that either I or other shops or even the customers had purchased after the typical FLAPS "would you like to upgrade to these?", had installed the plugs.
This was also around the time when VW & Audi quit using Bosch, I figured it couldn't be a coincidence.

I have at least 12,000 miles on my current set, in a VW. Not exactly sure. I never think about them and don't really keep track.
Put at least 80,000 on the last set ... until a rod started knocking.
¯\_(ツ)_/¯
VW recommended changing the stock plugs every 12,000 miles. The platinum plugs last much longer than that for me.

| Ok guys do I've checked the float bowls they have the big washers so they fill up less. Accelerator pumps backed all the way off so they barely work timing set at 12 btdc idle and 33 fill advance anything less the backfiring gets worse and I'm still running too rich and getting backfiring. Any other ideas? I haven't checked compression but as stated before I'm confident it's good seeing as how it runs like a raped ape when it gets to higher rpm. Any other ideas? Valves perfect at .006. |

Try checking your fuel pressure with a gauge to see if your regulator is actually working.

#1 or #2 exhaust valve stuck closed.

Or maybe, incorrect firing order.

Compression check warm. What are the numbers?
Points block rub. Is it lubed? Use the right grease!

Kindly explain how this would be applicable if either of those theories were correct:

My theory was based on just the last post showing that there was less exhaust flow from the right bank.

Because a raped ape wouldn't be able to run very well at all...

it is fouling the plug thingys.there is a reason for it doing so, fix that and you should be good to go.
as for the platinums Ive only used a few hundrad sets and had 1 that had a issue. a chevy caprice that got the dog shit run out of it all the time and detonated a lot, the owners son was a exspurt. 1 plug lost a electrode. FYI most any plug cam loose a electrode.Ive seen lots of plugs with them missing. the only engine Ive ever seen them not run good in is my YZ250 2stroke. it wont hit a lick.not even a fart. |

| So scratch everything guys I have pretty much come to the conclusion that this motor is pretty much a boat anchor it cannot and will not run properly or even at all I got 12 minutes of use out of it at the sand. I'm tired of fighting it I'm going to a 2.2 ecotec 😊. Screw this VW motor! But thank u for your guys help anyhow but I'm done with it. Anybody wanna buy a 1600 DP? Has kadrons and dual exhaust! |

No it wasn't. It was low compression, coupled with over 2psi fuel pressure! He needed to get the fuel pressure way down. Maybe 1.5psi. But that would only work a few months at best, because the engine is well used!

Hey Jim, you missed my subtle humor there. I'm actually a pretty big advocate for those 34 picts from Empi, myself.
