The bolts can be bought at ACE Hardware, as I have done in the past. Take the engines with you to double check. RTL Fasteners is another source if you buy in bulk. The engines look new from the pictures.
That is a good price unless some one gets into a bidding war.
I'm not worried about bolts, gaskets or even needle valve. What I'm concerned about is that these components, while perhaps new, are potentially a batch of components that didn't quite fit together well or are from an attempted version change that didn't quite work out.
Why would Brodak allow someone to buy their private branded main casting in bulk AND sell engines with their name on them via ebay. If they are good engines, Brodak loses sales. If they are defective pieces, Brodak gets a black eye. I was just hoping someone here knows the back story.
I'm probably not a buyer. The last thing I need just starting out in control line is to get sidetracked trying to get a buckets of parts to play nice together AND keep my planes out of the dirt.
