non French - spark plugs
hi all, how are these?
some are old, most show blackening around the ceramic, and I would say all are the lean side of normal, but not that bad...
they are the back 6 from the V8 motorhome, which has its maiden voyage to the new forest on Fri!
to my eyes, in real life, they are tan , light tan not white...

Gonna say John, there was only 6 there and it's a V8
To be honest, they do indeed look a tad on the lean side but not that bad. Was that picture taken after a run or a period of idling?
For a non-cat car'b engine, I'd like to see then just a tad on the more tanned side.
Where in the New Forest are you off to? One of the Forestry Commission sites? We used to go every year to a site called Setthorns near Sway. Absolutely lovely place

hi Jim took the other two out, all 8 the same..
they definitely are a light brown in the flesh... cleaned them all up with wire bush and checked and gapped..
the van was idleing for a few mins after a proper heavy 15 mile run...
I can richen the idle mix screws a few turns but the light colour may be caused by lean primary jets/ needles.. there is also a part throttle setting (basically the main needles have a limit of how low the sit within the jets, under low or part throttle) .. I could get an emissions test but I am not sure I need to , just pull a plug every now and again...
Jim I am going to Setthorns! looking forward to it

Excellent You'll really love it, free pitching in the trees and a proper point to empty certain tanks on the motorhome. I could be very tempted to come down and pay you a visit!jgra1 wrote: Jim I am going to Setthorns! looking forward to it
In that case, if the plugs look well tanned after a 15 mile run and just a spell of idling, not much to worry about at all.
Is it idling Ok now?
Did you get the bike sorted?

Jim you would be welcome for a tea and Mike's not far away >?
it idles a bit rough but I just dont know what a V8 carb engine should be like ? its got exhaust joint leaks which I dont think I can fix they may not be helping much.. the bolts are very very old and will snap
bike.. which one.. big one is nearly through an MOT, got a jobswroth on that really
the other remains unchanged
looking forward to the FC site! so the grey waste can be sorted easily
~? not worried about the other, takes a month

thats all white then all white,
John make sure you keep all your food under lock and key down there in the forest, or the poneys will knick it,
have you gopt an A frame if so you could take one of your projects with you,
just to give Jim something to wash the TEA and chocy bicys down with
regards malcolm

You're not wrong about that Malcolm It's not unusual at all to wake up and find a pony or deer looking at you through the caravan window!!!citronut wrote: John make sure you keep all your food under lock and key down there in the forest, or the poneys will knick it
Not sure an A frame is a good idea though. The RV itself is a biggie and with a project on the back, an HGV licence would be needed...

Personally, I would have thrown those plugs away and bought a new set, especially if you want to learn from them. Are they the correct heat range?
Did you not learn to do plug-chops on the bikes John? Can give you a run-down if you want but it's best done with a few new sets of plugs (expensive!) and I suspect it's not an easy task pulling all eight at the side of the road? Then again if you've got exhaust and maybe induction leaks, you'd best get those fixed first before fiddling with the fuelling.
I hope the weather holds out for you but the area is so unique it's still a wonderful place to be, even in a storm. I've got a guest coming down on Thursday and will be out and about myself until Sunday. How long are you down for?

hi Mike yep take your point about plugs.. they are all clean and free of rust now, so at least i have a starting point.. pulling plugs is possible. but not too easy... I would guess that the colour of one is prety indicitive of all though? all cylinders have good compression too.
The airfilter mixing plate (lpg) has an entry for lpg which I am not using at the moment, that is about 15mm entry for extra air into carb.. will block that.
I cant do anything about the exhaust flange leaks as soon as i try to undo the flanges the bolts will snap
there is another thing I noticed last night.. the offside downpipe has a vacuum driven flange within, it is supposed to block warm exhaust gas and send it back under the carb and out the other exhaust.. to help cold starting...
it is(was) stuck in this position all the time on test run...
I suppose this wouldn't help the heat of the engine/plugs (although engine was running between 80 and 90) it would lose a few horses too.
I cant do much more now, the trip is really a test run and I am out of time i will get breakdown recovery and i am pretty hopeful all will be well
Mike I should be there friday night till Tuesday morning. would be nice to catch up for a beer or come on over maybe..
we have penciled in cycling to an IOW ferry for one day..

if the engine is very lean.. if... what is worst case scenario.. holed pistons after an hour of running ?
I may get an emissions check from my local mot chap before i venture too far...
like I say, the plugs are light coloured but tan not white.. and there is at least one airfilter entry I will block off....

Maybe I'm being too cautious but I really think that if you can afford not to be concerned about a melted piston or two then go ahead and take the risk but if you've got serious doubts it's too lean, I personally wouldn't want to take the chance on a long run. Too rich, no problem but not too lean.
If the exhaust system is doubtful, I wouldn't put too much reliance in a gas analysis either - plug chop is the best and most accurate I know of. Can you not buy at least one set and do a few pulls? It'll be worth the peace of mind at least IMHO.
Sorry if this might have put the dampers on your holidays
