  1. Jaba There are no droplets of fuel if that was the case the carby is not doing its job. Also it’s not possible one side of the engine to run lean and other run rich. With all your knowledge you should be able to build the perfect jab engine. i modified my engine to run optimal but you keep saying this probably won’t work or maybe that won’t work.
  2. MARKDUN thanks for your comments I had a different air cleaner on mine with that pressure flap and it made little diferance. I am trying to convince everyone to install a air fuel ratio gauge.
  3. I don’t know the advantages of the intake Change good I would think. I had no experience with the 3300 only 2200. I changed the air cleaner used a auto filter I had the early corse fin heads at times I thought the heads where to cool. I have since sold the plane I believe it’s still trouble free flying.
  4. How do you know it did,not make any difference what where you trying to achieve did you say you have not flown it yet. How do you know if it is running lean or rich.
  5. The first thing you have to do is change the intake from nakaduct to side intake. Jabiru has finely done this, A naturaly asperated engine can’t have pressure into the intake. The best thing is fuel injections people say it won’t be reliable how many cars stop because of the computer injection.
  6. I am writing from hands on expereance my jab 2200 flew over 600 hrs with out any problems how much has all the other commenters have. You all have to read my first comment.
  7. The problem with jab engines they run lean. Monitor the air fuel ratio and be able to adjust and you wont Have any problems. Lycoming and Continental need mixture ajusment.
  8. A 6 cyl jab into a skyfox has already been done, kitfox in the USA have up to 180 HP. Have a nice day.
  9. Mate you want to read my reply you don’t get it
  10. I read a lot of suggestions of what you should do. I can tell you from experience the 3300 and 2200 are a very good engine the problem is they run to lean an air cooled engine rely on fuel and mixture to keep cool. and one of the problems is the nacka duct intake the engine cant have forsted air into the carb. jabiru have fixed this by a flat intake on the side no forced air to carb. I owned a 2200 4 cyl i fitted a air fuel ratio gauge with all the other gauges is indicated if it was running lean or rich. To ajust mixture I fitted a butter fly in the intake just after the nacka duck the old coarse fin heads where cool same the EGT. I done 600 or more hrs no trouble. Jabiru tryed to build a air cooled engine that we could start and fly with no ajustments lycoming and cont could,nt do that. I am not sure as to the new intake mod if this solves the problem but I would not fly a jab without the air fuel ratio gauge and some means of rich or lean device and your engine will last. I am not nocking jabiu they have done a great job manufacturing the engine. I hope in the future buy a skyfox and fit a 3300 6 cyl.
  11. With my jab if the batt does not turn it quick enough and cold mornings is the worst times. But I should say when it starts it will start all day. I rebuilt my engine and the flywheel bolts where tight with locktight. Cheers
  12. The battry people say it good to have a trickle going in when not in use.
  13. That is good to hear as I said cheaper battry less life do you use a solar panel Cheers.
  14. Thanks for your reply good point.
  15. i have a j160 2200 I have used in the past odyssey batteries 525 - 625 cca. The last odyssey was on the verg of quitting I rang around and heard about the Full River battries I was a bit sceptical. They are quite a bit cheaper I bit the bullet and bought one a 525 CCA. I have room on the top engine side of the firewall on the top so the battery sits vertical this battry is a little bigger so I didn't mind shifting it. The first time I started I was shocked it spun it over so fast none of the other battries where As good so if I get 2-3 years I will be happy. One thing I have added is a solar panel I would recommend any one To give these battries a go.
  16. Hi john It would sound yours was spark problem we read all the stories of spark or fuel in my case it was lake of fuel. The jab has the carb under engine so it has problem getting fuel up to the heads and the choke is a bypass jet. Works great on a motor bike carb is right at the intake port. Jab say it must spin at 300 rpm to start is that to draw the fuel up to the heads or to creat a spark.
  17. We must all agree jabs start excellent when hot.
  18. I would hav to disagree so what your saying at 100 rpm it may have spark at 300 rpm it would have no spark. Because when cold the jab won't start at 300 rpm. So what your saying cold 300 rpm jab won't start so put a half dead battery it will start. Next time cold morning a good batterie won't start I will try choking the inlet and see what happens. I will keep the forum posted on what happens. Cheers
  19. Hi Old koree I was thinking about cold start kit but the other day in the morning the batty was on the way out, I had forgotten to remove the intake foam plug. I hit the starter it struggled one turn then started boy did it run rich. Then after I thought if the engine has to turn at 300 rpm to create a spark how then did it start on just one to 2 turns. Another thought the coils come off a Honda motor they don't have to spin a 2 two 3 hundred RPM. I did drill the choke jet out to 1.2 and made a difference, so I am thinking is it not enough fuel or spark. .????
  20. One thing I would do when fitting long life plugs remove them every 100 hrs or so. Years ago I fitted, any one remember Golden Lodge plugs ?? To a Holden after a long time I went to remove one it broke off In the head it seized. Just a thought. Hyundai
  21. Ok guys thanks for that info I have one of the early 2200 engine first hydraulic lifter but I have converted it back to solid. I have the Honda coils. Cheers Hyundai.
  22. hey guys what type of iridium plugs for jabs (hyundai)
  23. I overhauled my engine at xmas done about 20 hrs puled it through one morning found 3 cylinders had very little compression i had used Grant piston rings. I stripped it down and honed replaced with Hastings rings all cylinders are up to specs now I wonder was Grant rings the problem ???? The engine sounds more crisp and performs better. What is the change over for D9EA plugs to dubble platinum plugs any one know. Cheers Hyundai
  24. I will keep mine at 15 psi will post if I have a problem.
