I have a new old stock Enya 53 four stroke, which I am about to run for the first time. It is ringed with a steel sleeve. It was manufactured around 1995. It has the air bleed carb.

Any thoughts on how this should be run for the first time? The Enya directions that came with it do not discuss break in. I searched this website but didn't find anything specific to a four stroke with a steel sleeve. I have broken in several Saitos, but they have chome sleeves so I'm not sure the procedure would be the same.

Thanks

I am not familiar with your engine.

However, I have had great service and prompt response to my questions on my Enya engines when contacting Enya directly. Mr. Ken Enya is extremely helpful and he may be able to give you the best answer on how to break-in your engine

I used Hobbsy's Saito method on my Enya 60-4C. Run the needle as rich as it can be set without needing glow support at 4000rpm for 10min. Then 5000rpm for 10 minutes, 6000rpm for 10 minutes and so on. I did this to 8500rpm and ran a few more tanks in a model at 8500 peak (rich) before leaning out to find peak rpm.

Isuggest fuel with plenty of oil.

Me too. I use only 20% castor in my 4C Enya. It loves it.

Thanks guys. I have not made any progress as far as breaking in the engine.

It seems that the throttle rotor binds. It rotates freely sometimes, and then binds sometimes. I think the screw with the spring loaded ball that allows the throttle rotor to be pulled out to choke is the problem.

I've inspected all parts carefully under a magnifier and can't find any burrs or other problems except maybe on the ball spring part. If I tighten the ball spring part fully then the throttle rotor locks up. If I back it out about 1/2 turn (which is how it was when I took it out of the box) then it rotates feely - sometimes.

I'm thinking of just buying a new carb. Does anyone know if a modern twin-needle carb (without choke) will work and fit on an older 53FS that that originally used the air bleed carb?

I guess I should email Enya, but I wonder how good their English is.

Thanks. I sent an email to Enya.

I'm impressed! Ken Enya responded to my email in less than 8 hours! And for anyone else who was wondering, yes, the newer TV carburetors are a direct substitute for the older air-bleed carbs. No modifications needed.

So I ordered a new TV carb from a seller on eBay.

Since I started this thread I thought I should give a final update.

I received the new twin-needle Enya carb promptly from the eBay seller. It fits the engine perfectly. The directions that came with the carb said that the low-speed needle had been factory set for best operation, but it was actually set very lean.

Once I reset the low-speed needle the engine ran perfectly. After three tanks of fuel I leaned the high end to an only slightly rich setting. The engine transitions well, has good idle, and good power. Looks like a real nice engine. I'm using 5% fuel, all castor, an Enya #3 plug and an APC 11x8 prop.

All Enyas are real nice engines ...

There is no need to change the Enya airbleed carburator against the TN Type, I had simply looked for the source of that binding you mentioned.
Enya airbleed carbs are fuel metered carbs too and working almost perfectly.
