International 345 v8 engine trouble? Answered

I have a 345 v8 international engine that will not idle. It runs fine if you rev it up but as soon as you take your foot of the pedal it will idle roughly for 20 seconds before stalling. I have put a new set of points in and also adjusted the timing correctly. What would be causing the engine to not idle. Also I have adjusted the idle screw and the place at which it will run is way to high for an idle so I can eliminate this as a problem. I have taken the top of the carby and can see that both jets are squirting as per usual. It has really got me confused this one. The only thing I can think of is vacuum advance but I can't see how it should effect it at an idle. Your help would be much appreciated.

Jet Engine Problems? Answered

I have been building a mini Jet Engine.  I have a VERY STRONG electric fan for the compressor.  Outer shell is made of sheet metal.  The fuel I have been trying to use is gasoline.  The intake is about 2.5 inches across and about 3 inches in it begins to close up to about 0.6 inch diameter where the air is compressed and mixed with fuel before being burnt.  The problem is that its starts but it explodes.  Is it too much fuel, to much compression from the compressor, to small of a diameter for the combustion chamber and exhaust or something else completely?  Haven't done much with jet before so any help would be appreciated. Thanks

Stirling Engine

I have a 4.3l v6 that came out of a s-10 pickup.  I was wondering if i could make it run on the stirling cycle? It is a 90 degree v6 so it should work, This is the only site i could think of to post this question on. I was thinking i would isolate the waterjackets to the right and left bank of cylinders then heat one side and cool the other. I am good with engines and am skilled in the garage. I'm just tinkering. Maybe run a generator with it if it runs. I have a welder, plasma cutter, ect and can use them. Just kinda throwin it out there...

Motorising boat

Any tips, please, on adding motor power to a 14ft Shakespeare speed boat hull without the high cost of a conventional outboard. I only need about 4mph for use on lakes and canals, so perhaps a lawnmower engine driving a paddle wheel or prop might do it, eg with a design like the fast boats in the Far East fitted with a car engine directly driving an outboard prop with the whole unit acting as tiller steering..

Instead of using compressing of gas using  combustion and passing gas and using spark plugs ..... shall we use a dipole magnet in the place of spark plug and and a magnetic piston with a pole on top side.if we rotate the magnet at the spark plug place ,when the opposite pole comes down .......the piston due to attractive force goes up and when like pole comes up it will get repulsed and goes down by this crank can be rotated.this is basically based on the principle of magnetic attraction and repulsion........ i am just a college student its just an idea that came into my mind......please say whether it is possible or not...
