ATCO lightweight starting

ATCO say you should run it on 16:1 but I heard on the internet that this can be a bit too viscous.

but that is using sae30 engine oil not proper 2 stoke oil we use today try 25:1 this will still give plenty of lubrication

plus the old sae30 oil will gum up the carb real bad hence why i said about ultrasonic cleaning the carb has this got the zenith type carb on it?

I don't know what kind of carb it has on it. :-(
But I have given it a really really good clean up.

Just to correct an earlier post, It doesn't start on starting fluid, it wont start at all.

Thanks abelw44
 
Also, thanks for the offer of ultrasonic cleaning, but I don't live in America so its a little impractical!

whats the compression reading? you want 100psi+ or you will have a difficult time starting it have you tried to spray 2 stroke mix in the air intake or dribble a drop in the plug hole and see if it will run for a few seconds on that? if it will this just leaves the carb to sort

I tried dribbling a bit in. Nothing happened. However is it possible I didn't put enough in?

thanks

As i said before what is the compression like you need over 100 psi for it to run ? it may be a crankcase leak or leaking crank seals this rules out a carb problem for now as it would pop on some fuel in the plug hole it may be time to strip the engine to investigate further

I don't know what the compression is like unfortunately as I don't have a compression tester, but that is something I should look at getting.

As for tge crankcase gasket, I made my own from a cereal box. I have done this before but only on a 4-stroke engine. Is this a problem?

As I said before is it possible I didn't put enough two stroke in the plug hole?

Thanks,
