SQUISH HEADS

Ive writen this quick blog just so people will know what one is and what it does . And besides I'm getting bored OF STANDING THERE SMILING TO MY SELF, KNOWING THAT A LOT OF PEOPLE  HAVEN'T GOT A CLUE AND I'M GETTING BORED with it all .

Ive been  listening to lots of different things on what a squish head on a tractor is, and what it is and where it is and all the boll------=s about it being this brass tube thing that goes in side the head and so on and so forth and so on ,

Right lets start with me and what i know and how i know . Any one who does know me will all ready know so sorry for boring you and hello to you all , Now I am an ENGINEER , don't take that lightly. I have built and tuned engines from old NSU quicklys to V10 SUPER CHARGED MONSTERS , Ive worked on steam engines , 2 strokes ,4 strokes, rotaries, diesels, Terra and marine , gas turbines, and jet engines, and of course electric , So I know a bit about stuff and things and you know i will put everything into what I'm doing as you can probley see by what I'm doing now on the blog . What the Hell is he doing this job for ? youre asking your self , BECAUSE I CAN ,and I am nearly 50 and these old tractors are puzzles. they are old and so many people have worked on them over the years, every single one is different and are someones history of their lives, their farms ,or what ever , I look at it as I'm doing my bit so they don't die and vanish . I will be totally honest with you ,I know nothing about tractors. I am an engineer I will find out what has caused the problem , and fix that, and then fix the damage it has done .
Right ,Squish heads .
squish refers to the shape of the inside of the head, the combustion chamber . anyone who has tuned the old 250 and 350 LC`s has had hours and hours of fun , tears and pounds spent, sorting these things out .have a look at the picture below ,

Its all to do with how the fuel mixes in the combustion chamber in the top of the head ,blar, blar,  blar AND AS FOR THE BRASS TUBE it has nothing what so ever to do with squish , Its to do with making the ENGINE HOTTER FASTER. it directs the water in the cooling system at the thin walls of the head around the exhaust valves so the engine warms up faster  DUE TO THE HEAT FROM THE HOT EXHAUST GASES.
So there you go , PS, and by the way if in doubt, RTFM, and if you want to know what that means Email, ha ha ha.

Sorry if you read the blog yesterday it dident make a lot of sense as i was trying to do 10 things at once.
