another rich cub!

Good idea Yaume, Must find some perhaps local agric dealer "Igol"? Thanks
Bretage à Bretagne par les Etats Unis!

Pat

j'achète mon additif dans n'importe quel magasin spécialisé en entretien de voitures, type norauto. je pense que ça se trouve également dans n'importe quelle station service.

un flacon permet de traiter 500 l d'essence. Ca me laisse du temps pour en racheter

Sorry for the non french speakers, I explain far easier in my mom's language.

yuame,
I've always regretted that I had not learned ANY French. I studied Spanish in grade school and at that age, things just stick to you and I retained a lot of it. Back when I had a real job I would travel Mexico and South America and was able to communicate on a very basic level with customers. I always enjoyed talking with the mill workers to get a feel for how things really were going. God, how they must have laughed at me when they went home at night and told their families how I butchered their language. But in Quebec, Canada, I was lost! It seemed like there were a lot of people who didn't speak English. But when I when I went to a restaurant, I was geeted with "Bon jour, mssr." When I replied with a "Howdy!", they knew my real identity, and imediately replied, "Good evening. May I help you please?" Sacre bleu!

Does this make sense? I don't know any French beyond oui and non.

Je considère l'additif pour être une perte d'argent.

[Lurker Carl]

Well said, Jim.

[Patbretagne]

I'm just a new boy ready to listen to anone's side of the argument. The question now is shall i "perdre mon argent" or shall I Burn some valves up?
Thanks anyhow,
Patrick
PS When I came over to France 16y ago I only knew oui and non! now I speak Franch "Like a Spanish Cow" as they say!

Got it.

But is gas leaded on your side of the atlantic Ocean.

if not what is it replaced with?

As long as anybody won't demonstrate me that additive is a loss of money, i'll consider that's it's a cheap inssurrance for some 50 (well 48) years old valve seats.

I must be wrong but...

[Patbretagne]

Basically No "Essernce" or to us english petrol or the other side of the pond gas is not leaded, it's called Sans Plomb "Without Lead" there are 2 grades 95 and 98 Octane. We still have Super which in UK used to be 4 Star which could possibly still leaded, That's a question for you Yaume.
I think I'll have a go with an additive, there's alwas the chainsaw, cultivator and lawnmower to add to.

[yaume]

yuame,
how they must have laughed at me when they went home at night and told their families how I butchered their language.

Well, I suppose you're laughing at me now...

But in Quebec, Canada, I was lost!

don't worry the situation was exactly the same when I've been to US

[Lurker Carl]

Engine manufacturers installed hardened valves and seats because the emission controls used to reduce pollutants (leaner air:fuel ratio) increased combustion chamber temperatures. I have not had access to leaded gasoline in over 20 years and never experienced valve burning. I have never used lead additives in my motley collection of old stuff, all of which was designed to burn leaded gasoline. Tetraethyl lead was added to gasoline so higher compression ratios could be used without the fuel combusting spontaneously before the ignition system fired.

[Jim Becker]

Gasoline on the west side of the Atlantic hasn't had lead for a couple decades. Take a at the second page of this thread for an earlier discussion of this topic.

history of French Gas...

for decades we had choice btw 2 types of leaded gas : "ordinaire" (basic) or "super" (do I need to translate?) which had higher octane level
in early 90's unleaded was introduced (two grades as Pat already said).
"ordinaire" gas was no longer produced but "super" was continued until most of the old vehicles, which couldn't use unleaded, died.

last year "Super" was stopped too.
but there was no more lead in it for a couple of year. lead had been replaced in it by "anti recession soupape" additive.
so whe had two type of unleaded gas : the real one and the one which was supposed to be leaded and wasn't.

what we do by adding additive is home made "Super".
may be french cubs have softer valves seats who knows...

Patrick : I ve taken photos of the engine tonight, i'll sent you them monday at office.

Well, after reading everbodies comments I went back and rechecked everything by the book and found a few things that were not up to specs. After getting the carb back on I noticed the choke yoke, the part that hooks to the rod was tight as it could go but the choke shaft was able to move a 1/4 turn freely, also altho I had changed the oil in the air cleaner (which did not look dirty) I checked again after only a few minuets of running and it was dirty again so I checked the wire mesh which was very dirty. It has good compression in all cylinders and the gaskets in the carb all look good. After tighting the choke shaft and cleaning the filter and a new set of plugs and she started up real easy but I did have to use the choke this time so I think it may have had the choke partially on before. Got 'er going just before dark and sounds real healty and not as much black smoke as before; didn't have time to put her to any work today but looking forward to grading some ground tomorrow. Nother thing I noticed when I was running it standing next to it and gave full throttle the speed control would not hold full throttle as the metal is worn away,------so when I was digging hard with it the throttle was three notches from full throttle, could that make it run rich: pulling hard with partial throttle.
I had thought the cub was under powered but driving it around holding the throttle wide open, it has a lot more power then it seemed to. I suppose I can hit the throttle control with a little weld and then file it down or is there an easier way? Wheww! a lot of questions! but thanks for all the help. I think maybe I'm getting 'er close to right.

Ok I haven't gotten past rebuilding the carb yet I got the warps in the carb straited up. I ran it for an hour and it is a little rich the plugs are black with some fluffy black buildup. And the timing is probally off.I am waiting for my brother to come over with a o2 sensor and meter to read it and get it set for me.

But I was thinking last night these carbs have been around a long time and all it would take to mess them up is a farmer using a torch tip cleaner on them to clean them and this could be why some are off and others are not. On any other carb the idle circut has very very little to do with the main circut you always adjust the main circut by changing the main jets ie the size of the hole in the main jet I think of my cub a "new cub" becuse it is a square nose 64 but it is still 41 years old so it has had 39 years of peaple dooing things to it. I know around here when you need to clean a small hole wire is too soft and everyone uses torch tip cleaners or a little drill bit. And most farmers have torches and tip cleaners.

I will write back after I get my carb adjusted or if I don't and let ya-all know how it went.

Glad you finly got it . Like my old teacher back when i was school use to say . Do it over. Never said it was wrong. I always found out it was .
Now on to the fuel. By takeing the lead out of the fuel didn't cause the valves to burn. It took away the cousion as the valves closed. steel to steel hammering away doese What? Our tractor get sush little use that it's not a problem but if your going to work it hard allday susch as plowing I would advise you to put in a lead additive or a 1/2 pint of mystry oil or any oil w/lead. Just don't over do it . The ash in the fuel will cause foulinh. "Jack"
