Re: Re: engine manifold mystery
<table>
Good info John:
I do intend to run a vaccuum hard line. It's just going to be a larger diameter to match the dist & carb fittlings. It should suck much better.
The evaporator tube is no where near 14" long or bent in a U. That's a good idea and I'll install a new one.
You just solved the mystery of the phonolic gasket. My carb studs are too short and I was thinking about removing the gasket. I'll look for longer studs.
The muffler noise may be my imagination. The engine truck lid is removed and the tailpipe extention isn't on yet. I'm going to drive it to the local muffler shop to have that piece made up. It's the shop I used to expand the J tube to properly fit into the muffler. And get this...There's a rumor that the muffler shops owners father is the original owner of an Amphi that hasn't moved in 25+ years. Can't wait to get back there!!!
I'm going to investigate the VW carb further. My VW Solex's were so simple and easy to work on. The electric choke was great. Rigging athrottle cablemay take some engineering.

<tt>Glenn -
I would not replace the hard advance line with rubber. As the engine
compartment gets warm and your line gets older and softer, the
vacuum will likly collapse the line affecting your advance (that
would suck... not! - OK, that was bad!). That is why it is a hard
line to start with. Replace it with a hard line or try to unclog it.
The fuel drip tube is another story. I prefer mine to operate, it's
easy to replace with tubing and fittings available at any hardware
store. Be sure it's about 14" long, bent in a "U" shape in the
middle.
Interesting thought about the V-dub carb. I may give it a try on one
of my cars. I have dual SUs on my driver now. Cold blodded at first,
once it starts to warm up, it runs much better. When the Solex carbs
are properly tuned and in good operating condition, they are a good
choice. Only problem is the boiled gas syndrome. Proper phenolic
gaskets will cure that almost everytime.
I have a Gordon muffler on my car, and it is very quiet and I get a
lot of comments on how quiet it is. Are you sure what your hearing
is not the cooling fan noise? That is a common thing with the
Amphicar especially from inside the car.
