| Subject: | Re: Long term engine storage feedback |
Thanks Gil -- When I get to it (operative word: "when") I'll do the seal for
sure. I'd like to think the oil that was poured into the cylinders could fight
off any rust, but again, I've never been down this road before.
Thanks again for the feedback --
Andy

Thanks for the advice Jim. Can't wait to get at her, but forever a year
away . .

have to agree with Cliff, don't worry about it. With any engine I
recommend a real good filter (20 microns or less). Simply keep an eye
on it and your chip detector. BTW there is a drain screw on top of the
carb, for draining the preservative. It is the only one not safety
wired. MAKE SURE YOU SAFETY WIRE IT AFTER DEPRESERVING IT. Not doing
so, will cause an engine failure.

time rebuild. Yes it is preserved as completed by Motorstar, Bacau -
Romania, however, as it sits now for 7 coming on 8 years in my insulated
but not sealed home shop -- Nashville, TN -- I was hoping to get success
stories from folks who have come across similar time frames when running
for the first time. I keep changing out desiccant bags installed on
shelves inside the wood crate on a fairly regular basis, but with the
Nashville humidity, I still stay worried. I would think the plastic
(4mil?) wrap, brown thick paper, oil in and over the engine, desiccant
plugs, etc would do the trick, but I've never been down this road
before.
