    Prop problem

    If the Blades Flex, the Magnitude is very small, in the range of Fractions of a Millimeter. Put a Pair of Vise Grips on an Aluminium Blade, and see how much Flex you get...

    Prop problem

    If there is any flexing of the Blade it is likely in the Range of 1/100" on an Aluminiun Prop. That bit about Blade Flex has sold Hundreds of Thousands of SS Props

    Converting Roller trailer to bunks for my Starcraft 161

    That Trailer looks like it uses a lot of EZLoader Hardware from the late 70s. Is there an EZLoader Distributor near you?

    Cars you should have kept.

    Hmm, it rode like a Car should, the 455 could move it fairly well, especially if the Factory 2.56:1 rear axle was changed to a 2.73 or 2.93. Mine had the Heavy Duty Brake Option. As for Rust, it took over 10 yrs before any appeared on mine. Of course we didn't have Muttonheads Salting the Roads...

    What didn't you like about it. I had one, it was a decent Car, even ran with the Engine Bay jammed full of Snow, after a night in late April 85. Was running when I took the Pic

    1969--85hp Starflite, model 85993E possible carb swap?

    I'm partial to NGK. The ones that came in my 1984 115 Merc, were still in it, with about 600hrs on them when I traded it in in 1998. As for Champion, I wouldn't them even if a Gun where to my head, unless there was no other choice

    Johnson CD-12 5.5HP

    There is nothing that grounds the Ignition as the Throttle is turn to stop. It is simply the Retarded Spark that Kills the Motor. Go over your work again. Is there a chance you have shorted the Points to Ground?
