    Thom, no heat problems with the Jabiru engine. I am having carb-ice problems with the bing carb the minute the temp drops below 60 degrees on a humid day. No problem here in Texas during the Summer, but this time of year it gets your attention. I looked at the electric heating element, but chose the TBI instead. A little more money, but a lot more in fuel management. I did put that message on the Jabiru list, but no bites yet. I'll take your advise and try the Yaho sites. Thanks Colin Hudson Mark IIIX-tra with Jabiru Temple Texas On Thu, Dec 20, 2012 at 8:26 AM, Thom Riddle <riddletr@gmail.com> wrote: > > Colin, > > What are your "heat problems" with the Jab running the Bing 94? I have no experience with the TBI but have a good bit of experience with a Jabiru 2200 on a Kolb Slingshot. Perhaps I , or one of the other experienced Jabiru/Kolbers, can help. > > If you are determined to change to TBI, I suggest you ask your question on the Jabiru Engines Forum on Yahoo Groups website. In any case, they will want to know what you mean specifically by "heat problems". There are several on that list who have changed to TBI or AeroCarb, some with success, some not so much. Most of them (tractor configurations) did it to have manual control over mixture. If that is your desire, installing a HACman on the Bing will accomplish that, or even making your own is a fairly simple process. That said, I was able to get the EGTs with the Bing exactly where they should be at cruise and full power climb by installing Jabiru's economy tuning kit. > > -------- > Thom Riddle > Buffalo, NY (9G0) > > Kolb Slingshot SS-021 > no engine > FOR SALE > > Diamond Katana DA20-A1 > Rotax 912 F3 > > Don't worry about old age... it doesn't last very long. > - Anonymous > > > Read this topic online here: > > http://forums.matronics.com/viewtopic.php?p=390740#390740 > >

    From: Richard Girard <aslsa.rng@gmail.com>
    Wakata, all, NEVER, NEVER, NEVER use any product containing silicone on any painted surface or surface you will paint later. Silicone CANNOT be removed, EVER! Silicone is like molecular ball bearings, you cannot remove it by any method. Sanding or wiping simply spreads the contamination around. Nothing sticks to it so any contaminated surface cannot be painted effectively. Ask an autobody painter. They have a special primer that attempts to encapsulate the silicone and it works well enough to get the job out the door, but long term, the paint will come off. I spent many days in Boeing training classes getting certified to inspect sealing. Boeing practices complete segregation of silicone sealants and tools that are used to apply them. Their only regular use for it is to install windows and only then because they have never found anything that will handle the temperature and pressurization cycling to which an aircraft is subjected. Their painters hate the stuff almost as much as they hate rivet tape. If you're not convinced, do this experiment. Take some RTV and lay down a bead on a piece of scrap and let it cure. Spray with primer and watch what happens. The primer coagulates but doesn't stick.
