Rear cylinder plug fouled as f....
Hello gents. Back at it. 1976 FXE 1200. New pistons, rings, bored .30, heads cleaned up, with 350-400 miles on it since work done. Starts right up with a good kick, runs awesome and sounds great. No running issues what so ever. My plugs however are burning a bit differently. The REAR cylinder plug is looking fouled and kinda has carbon OR oil “caked” on it on one side and the other side of plug looks clean. The FRONT looks like its burning very clean maybe even lean. Let me know what you think if you could and/or what could be causing the difference in plugs. Its my first shovel so learning as I go. Here are some pics below. NO smoke or symptoms at all coming out of rear cylinder (fouled plug) no back fire or popping etc. thanks in advance!!
On a side not I have been pretty easy on her and havent Really opened her being new motor work. Maybe it’s time to give her a good rip and blow her out? Thinking of tinkering with air/fuel mixture.

hmmm ok I’ll have to check it out. I installed it all but wondering if a seal didn’t sit as it should on the intake. How would I know? Just take it off and re install it? Thanks!

ok will do. Ok a side note... my front exhaust has the “sag in it” bc of the one bolt mounting style... could I use an exhaust sealer like “accosta seal” or high temp silicon to fix that. I’m not sure if there is an exhaust leak bc of it but wanna be sure. Tried the evo gasket crunch method but didn’t like it at all.

The chemical in the brake cleaner is Tetrachloroethylene. When this chemical is exposed with excessive heat (used in welding, and combustion chambers) it can produce phosgene.
Some Phosgene facts. Google Phosgene and read more!
It can be fatal with a dose as little as 4 parts per million.
Symptoms can be delayed from 6-48 hours after exposure.
There is NO antidote for Phosgene.
Long term effects can be chronic bronchitis and emphysema.

the under side of the front plugs electrode has oil crust on it to as well = I would check both heads
today nothing fits like it had in the past don't know if you put a cam in the engine when you did the heads but today that changes everything
if you did guides then to expect the top the place the seal goes / on might be taller / most actually are this way today - and if so then the travel or the distance between the bottom of the top retainer and the top of the seal installed - may not have enough distance and it bottoms causing a new seal to be damaged --------- you get the rest
