Jab engines rely on rich mixture to keep them cool so a drop 26 to 18 ltr an hour means the engine is running leaner. .?????

The AFR gauge works with the EGT o monitor your engine depends on the temp out side at times it will run without richer mixture. I bought mine from eBay but I looked and the one I bought no longer there but other models. Mine bought a oxygen sencer Holden commodore fitted to exhaust On tail pipe 2 inch down from tail pipe weld. I have done 530 and no valve probs as yet touch wood.

Ok I think FI will be my next project. What is the noticeable power gain on the 2200.

I have a 2200 jab it has Air/ fuel ratio gauge a must, EGT,s on 3-4 1-2 coming soon gauge that is. And last a 2inch butterfly on the intake into aircleaner. On cruise it will lean out I just close the butterfly a little and that riches it to Rich of peak. I don't know how I could fly it without this setup.

I have been very interested in FI for 2200 jab I think it would sort out the EGT different on cyl. Has there ever been any ECU failures to date as I would keep the bing as backup. The problem to date is the ausy dollar not good.

Has anyone had beed slip due to low pressure on 10 ply tyres. By the way jab brakes are not good enough to slip the tyre I am sure. I want to add the extra jab calliper to my jab any secondhand out there.????

Hey Russ Yes I know what you mean but they are so tight on the beed I don't think they would slip ????

I just bought 2x 10 ply tyres from jab for my j160. The only thing I found don't put to much pressure in them as the are very rough. I have 15 in them still a bit rough on grass strip.

I read what you say John about Nikasil we have to look at other engines like Rotax they reach TBO. I was talking to Stiffy he explained that it is very hard and expensive to manufacture a barrel and head in one and then Nicasil it. I wonder what cont and lycom do with there all in one cylinders.

Thanks Nev I did talk to the bolts guy but the next size up was to big. Any way all is good it was not stripped.

Good news for me the barrel thread was not stripped, somehow I fitted a shorter head bolt by mistake and it just pulled 2 threads out. I drilled slightly into the thread and retapped it and all is good boy am I a happy Chappy. And this is on my jab 2200.

Hey guys I have a problem one head bolt has stripped in the barrel. Not much room for a helicoil. .????

So where are you getting all stated information from so you think CASA should sit back and say nothing. I don't roast Jabiru but when a engine is developed you have to make the engine for all pilots Jo Jack and Jill I as a mechanic understand how an air cooled engine works. Your office Jock in most cases don't and this is the problem. If Rotax where air cooled they would have maybe the same problems. CASA are a governing body they don't have to state anything.

I think you all are missing the point CASA is a aviation governing body, If a 747 kept having engine failures they would step in and demand a fix to the problem for our safety. Jabiru have learned a lot from there early days I was down at jab last week and they are testing the new 2210 there is no fly it for a few hours and put it on the market because CASA are looking over there shoulder. I believe they Jabiru will get it right.

That is good Dazza when it comes to spelling it does not matter unless you are writing a document for the courts.There is a thing on the internet where all the letters in the words are jumble up and asked can you read it, I can because we as humans don't look at the letters in a word to be able to read it. But I will remember the word hydraulic in the future thanks for pointing it out.

Dazza You really should get a life.

I just came back from jabiru talking to Stiffy and i can tell you they are developing the new engine testing testing and they will find all the problems. I am sure when it goes to market it will be right. As the person who made the LCHeads who just tested for a few hours and sold to the unsuspecting public yes I bought them a big list of problems they should have tested for 2-500 hours not just 6 hours and say yes temps 180Deg on the market sold.

Good to hear Phill as I have said on my other thread you need fuel ratio gauge and EGT, gauges I have to richen up on cruise at times. They say compansating carb I don't know does not seem to work on mine.

No not kidding I have tested the gauges and they do read about 10 deg lower with a manual digital gauge. I believe I could not fly my jab with out 2 EGT gauges and a fuel ratio gauge. And you also need a way of altering your mixture.

One thing you must remember it is not up to the controllers to determan weather you are legal to fly in to CTA it is up to you. They will give you clearance in most case but if CASA is on the ground they will Nab you.

With all the high tech talk on this forum put your heads together and make the perfect engine. Yep all talk I think. I have removed the LCHeads from my Jab done a 2.5 hour flight temps where around 190 - 205 F on cruise I am happy with that. I don't know why I put those darn LCHeads on in the first place. On take off I lift off push the nose forward get the airspeed and let it gain altitude, no pulling the stick back to impress the people on the ground. You can do that with a rotax 912 not a Jab.

O yes B/S they come into the question Of aviation no I don't think so. Every one must sleep with the light on.

Well it's good to read that another LCH owner is happy with the temps but unhappy with oil leaks, you say your rocker shafts are turning there is only a grove on one side of the shaft so it is not possible to turn.

The D motor is very old school, side valve, who know,s it may be a very good engine. Side valve engines stopped being Made 50-60 years ago.

Rotax and vw have xflow heads and they are very reliable engines. So how do Rotax do there heads xflow and water cooled. You say we are considering a engine who are we.
