2 stroke engine help

Captain Gorgeous /

i have this tiny 2 stroke engine

and unfortunately some old/bad gas was put into it

i dont know if this is the problem or not

but the thing wont start

the block and all is fine

i pretty sure its not the engine itself unless the gas did something to it

so im guessing its something to do with the carb

oh yeah

i know its not the timing

it has a glow plug

fuel is getting to the chamber

something comes out of the exhaust

it running real rich right now because i have to break the engine in

and something that looks like thick oil comes out of the exhaust too

which i think is just the oil coming out of the chamber that just collects or something

but i dont know why it would be thick

can you help me?

a problem with the carb is my best guess...

Hey Captain,

Is this a model airplane engine?

What year, model, brand of bike is it. If it's a lawn mower, you are outta here! :)

Chris,

It is tiny.

It has a glow plug.

I think it's a model engine.

What the hell is a glow plug?

Chris,

It's a plug that glows.

OK, it looks like a spark plug and you hook a battery to it to heat it up. Compression ignition engines like diesels use them to assist in starting.

Kinds like a glow worm. Remember those from when you were little. You give them a sqeeze and their face would light up...oh, those were the days. :)

Man, Do I ever feel old now! It does sound like a little Cox engine.

If it's a model airplane engine with a glow plug, you probably need to run model airplane fuel, such as Byron fuel, that has a Nitro Methane content. I haven't heard of any airplane engines that run on regular premix

Geez... Steve... Why would a question about a model airplane engine make you feel old ?... LOL... they still make them yanno ??

You feel old?... hell... I just feel hungry. ; )

Re: 2 stroke engine help

I know Fred, I guess it just brings back memories of a birthday present when I was about 9 years old. It was a Cox airplane. Not the remote controlled kind they have now. This one was attached to a dual line, maybe 20 or 30 feet long, that attached to a handle and you had to fly it around in really fast circles until you got too dizzy. The only control you had was up or down. And usually down wasn't very controlled at all. Zis ring a bell?

Steve,

Near as I can recall, it was once up and once DOWN!

Re: 2 stroke engine help

2 stroke gasoline engines are very common in model airplanes! I built a 1/4 scale Super Chipmunk that has a 62cc chainsaw engine!!!! Runs on the same fuel as your moped!!

May be true, but did it have a glow plug?

Ron

Re: 2 stroke engine help

everything looks good

i just think its the carb

as for that plane with the 20ft long wire

theyre called control line planes

sorry it took me so long to reply

ive been out of it

Captain,

This is even worse than the average ped, as there is even less to go wrong.

If you have enough compression and a good glow plug, you should be able to splash a little fuel in the intake and get it to fire up momentarily.

Will it do this?

no it wont do this
