Go to http://enya-engine.com/Parts_E.html and scroll down for the needle valves and the venturis. If you email them and say which engine it's for then they'll either have one of the original alloy venturis or a suitable nylon type. As a guide to prices, one yen is close to one cent.

I like their ST style needle valve .

ok..am familiar with the Enya nva..with the springy extension..and I know the ST spray bar and the Enya must almost be the same size...but are you saying that Enya has a ST type needle valve also...or you just like the St one...sorry to be confusing the issue....

Is the shipping for things from Japan expensive...seems like there ought to be a source for those old nva except having to get them from across the world...

It has worked out very well for the Enya devotees so far. Shipping is four or five days

Scroll down the link above until you get to the needle valves. The first one is the ST type made by Enya as an option for their CL stunt engines. As Jim indicated, the service and prices from Japan are very good.

Hmmm..think I am doing this right...Is the price for thr st type NVA like $19 compared to the Enya conventional
NVA $6.00...that seems like a hell of a disparity...just That doesnt seem correct..someone please advise..

thanks..joe

This is precisely why the end user should never disassemble the engine when still under warranty. Send it back to the folks that know the engines. And I agree with others that said that if the engine is still under warranty, the Altec folks should fix it. Maybe they will...

There are lots of folks that waste their money buying STP and other oil additives out of ignorance. Does this mean that we should accord them equal credibility versus the engineers that design lubricants for autos/trucks/model airplane engines? I don't think so, Tim.

Castor oil has been proven superior for most model airplane applications for many decades now. Others have tried, but no one selling oil in the US has made the grade (excluding Cooper - not familiar with his products). Furthermore, if the manufacturer says to use all castor oil lube, there is no justification not to do so. Fox engines ran great on all castor lube, but if you switched to synthetic, even with a tad of castor oil, you grossly shortened the engine's useful lifespan and lowered the engine's performance. Sometimes, just once in a while, the old things are still the best things and sometimes the old farts are right.

I went through an "all synthetic lube" phase in the early Eighties myself. I hated getting that gooey castor oil all over my pattern ships. I did make out okay with the synthetics, but you really had to be on your toes regarding tuning, especially when using a tuned pipe.

I'm using model slang here, so no one need to display their pedantic side by correcting me. Although, if you really must, I guess it is okay. <G>

I lived in Japan while in the Navy. I bet Mr. Enya will serve you well. Sent your engine to him. Japanies people are very proud of all the do. Bet he only charges you postage.
