VALVE EAS

Postby BOATCH » Fri Sep 28, 2007 12:50 pm

I was wondering if there is not a easier way of decarbing your motor.Wat about valve ease or some of these new additives on the market . Will aditives mix with the two stroke oils and would it lose power . Not that i would use it but would like to know .

I personally wouldnt......... a two stroke motor doesnt have traditional valves for inlet and exhaust ports, the piston acts as the "valve" ....... it could possibly work on other parts such as sticky rings or carboned exhaust ports... but once again i woulnt take the chance....

I've posted this answer before.
In short.....NO.
Some others on the forum disagree but I stick to my "NO" answer. It MAY help in some cases where the carbon is wet but once it has formed a crust, forget it........

Is it not possible to perhaps do it so regulary that this crust doesn't form?

I remember previously when I did mine the "easy" way, many people suddenly did theirs. Also I know on mine I had quite of bit of crap come out - yuk. I can't say I agree or disagree only that I try follow advice of those with many hours - you being one.

The advice I received initially was every 50-75 hours and from new. That person has almost 800 hours now and not physically decoked, this being one of many of their engines?

What would the symptoms be of an engine that needs a good scrubbing, ie the spray ain't doing its thing?

Will the Valve-eze not dilute the oil in the fuel and thus clean out carbon as it is supposed to do but at the same time lead to accelerated wear in the cylinder?

In the early 70,s I put some valve eze or some such product into my Datsun bakkie fuel tank.It sure cleaned the engine but my compression went south as well, then the engine made a hell of a noise and clatter.

On stripping the eze had done its job very well, no carbon but rings and piston and bore worn well byond limits. This was an old engine.

My advice would be do the maintenance as laid out in the Engine Manual at the reccommended hours.

You rely on this engine to perform so treat it right.

Just my 2 zim cents worth.

Kind regards,

Gunter Rostek

I can live with that and there's merit in that method. But don't use valve-eze. Gunter is right, that stuff's gonna eat your engine up.

When no gunk and slop comes out when the spray is used :D :D
