diesel weed eater

My weed eater was returned back to me with diesel in the tank. What can I do?

I tried starting it this morning and was having trouble. So I checked the gas tank and there was diesel in the tank. I dumped out the diesel and put gas/oil in the tank. I sprayed starting fluid in it and got it to start, but it was blowing a lot of smoke out of the exhaust and then died. Now I cant get it to start again. What can I do?

The diesel did not hurt the motor. It has more lubrication in it than a mix of 50/1 or 40/1. The problem is that diesel has a low flash point than the proper mix. The compression is not high enough for diesel to work.

That you got it to start once says a lot! There is a fuel additive called Start. See the link below to see what it looks like. It has ether in it and solvents to clean. The bottle is intended for a gallon or two of gas. Weed eaters usually hold less than a pint. With 8 pints to a gallon, you can see that maybe you will want to put it into the tank with an eye dropper, OK? (( But if you get a little too much, it won’t hurt. Put the additive into only half a tank of gas, so that after it starts and gets hot, you can stop it and fill the tank up with regular mix, if you think you got too much “Start” in the tank. Then fire it up and go again.))

Push the primer bulb 5 or 6 times. This will get the diesel out of the carb. good enough to get it started. When the primer bulb is pushed excessively the fuel simply returns back into the tank.

With the air filter removed, open the throat of the carb and put a quick shot of starting fluid into it. Set the choke for starting, turn the run switch on, And give it a pull. The starting fluid sprayed into the the carb will evaporate quickly, so you move quickly after the quick shot into the throat.

    What was involved in converting a gasoline engine to diesel.
    didn’t GM do this with the 6.2 or 6.5?

    See, I’ve got this small two stroke gas weedeater engine, and I’m wondering what would be involved in converting it to diesel, if it is possible.
    I’m thinking that I could.
    fill the bottom of the engine with oil, and increase the compression ratio alot.
    Thats all I can figure out right now off the top of my head..

    I have a smog pump from a truck, I could probably rig up to be driven off the engine, which would be some kind of forced induction,(similar to a supercharger, I guess, as it would be belt driven not exhaust driven) and I could either mount the carburetor onto the pump and have it put the diesel/oil mix through the pump and into the engine, or have it “blow” into the carburetor.

    Not really sure what to do about the spark plug, would I be able to keep it or make a glow plug?

    maybe theres a way to eliminate the carb and make some sort of injection system.. I dont know. would just like it to run on diesel normally.
    This is the engine..

    The 6.2 and 6.5 are both Diesels that were always Diesels. I believe the 5.7 Diesel used by GM for a couple years was a convert motor, which is why it had lots of problems.

    It really isn’t possible to turn a gasser into a diesel without pretty much redesigning the engine. Even the 5.7 was a diesel from the start. Chances are that the compression ratio required for diesel to ignite would blow a weedeater motor apart.

    Btw that converted GM engine you are talking about was a 5.7L diesel and they converted it over to gas, as a lot of owners had problems with them.

    Turbo

    Did anyone notice the video in the sidebar for the turbocharged lawnmower.

    GEARSTIX, I’ve thought about this for at least 10 seconds now, and I can’t think of any reason you couldn convert it to diesel. If it has a removable head you’d have to fill in the combustion chamber, or if there is enough metal milll all the combustion chamber off to raise the compression ratio up to where it would autofire the diesel. Perhaps a billet head would last longer, but may need some cooling fins to dissapate heat.
    A two stroke engine has no oil in the crankcase, so don’t fill the crankcase with oil. It would just pump the oil up into the top of the engine and too much of it would hydrolic lock the engine and bend the rod and boom. The other problem is how to meter the fuel. The gas carburetor meters it with air. Dielsels normally run full open air, no throttling.
    Now if you could rig up an injector inplace of the spark plug and have some way to get fuel to the injector you could probably make it run, but probabley not be practical, but may be fun to mess with. You might want to find some reading material on an old detroil diesel engine if you could find any, they were two stroke.
