| Subject: | Firestar rebuild |
- After a couple of years of my kids needing money more than I did, I sta
rted working on the Firestar again.- The 447 had been pickled in fogging
oil, and one of my sons had never heard it run.- Got it off the trailer,
unfolded it, tied it down, and put a little gas in the tank.- First probl
em- couldn't get any gas up to the engine.- I have a bottom feed tank, an
d some gas was leaking around the grommet.- Can I use some gas resistant
RTV to seal it?
- Second problem- the elbow at the bottom was rusted inside to the extent
that gas wouldn't go through it.- I should have left some gas with Stabi
l in it.
- I jury rigged a gas can to the plane, and put the primer bulb back in.
- Tried to start, and the bowl gasket leaked.- Took the gasket off and
re-installed, and the leak stopped.- the engine fired right up and sounde
d good.- I could only get 5100 rpm on it, so I have to adjust the prop pi
tch.-
- Another problem- looks like all the rubber cracked.- The cable boots
split, and the 3 year old carb mounting rubber doesn't look that good.- A
ll are Rotax parts, so I am going to try JBM this time.
- My 32 year old son was like a two year old at Christmas.
- Lots more work to go, plus the trailer.

First: Don't use RTV anywhere in your fuel system, even supposedly "fuel resistant"
grades will be eaten by raw gas. Get the proper rubber bushings, you can
likely get them at your local lawnmower shop, if not, one of the aircraft supply
houses like ACS, Air-Tech, or CPS. They'll have the metal fittings, too.
Do replace the carb bout, cracks lead to air leaks which lead to lean running which
leads to a seized engine.
Low rpm could be too much prop pitch, or it could be carb jetting or something
else. Is it the same prop from before?
What's left to do?

- I just put in a big order to JBM, so no RTV.- I had to change the pro
p blades after it flipped over, and went conservative on the pitch.- I al
so put in a carb rebuild kit, including a new enrichener.- Runs a lot bet
ter now, but I won't play with the carb adjustments before the pitch adjust
ments.- Another week, weather permitting.
