Question
is there a muffler for enya 40-4c?

recently, I bought a vintage enya 40-4c and I couldn't find a muffler for it.
not sure if there wasn't a muffler for this in the first place or just hard to find.

I did find mufflers for a similar engine type 41-4c on enya's website

1 website says the 40-4c doesn't have screw thread on the exhaust port. is it true?

Not sure if it work?

The Enya .40-4C is an early '80s engine with exposed rockers.

Originally it was never intended to use a muffler and did not include one.
Its noise is not particularly offensive and it made rather little power.

The .46-4C is stronger and the angled valves .53-4C was a Thoroughbred capable of exceeding 14K!

If you want you can improvise something to quiet it down further still.
I think the muffler for the .53-4C might be suitable, if the exhaust pipe is the same diameter.

The ASP/Magnum FS-52's exhaust hardware should be compatible...

Dear Murcielago:

The PIPE Here...I've got an Enya 46-4C AND 60-4C myself, and I've seen the exhaust port threading as being spec'ed as an M10 x 0.75mm thread, the same as used on the OS FS-40, -48 and -52 mills, and on the ASP/Magnum FS-52 four-stroker mill as well.

The ONLY engine maker that uses 1 mm thread pitch on the majority of their mills IS Saito, which only uses a 0.75mm thread pitch on their smallest FA-30S and FA-40a mills. Everyone else seems to stick to the 0.75mm thread pitch for their mills, so far as I know. I've also requested RCGroups to make a "sticky" thread for just such needs, and some responses have agreed with that idea.

The ORIGINAL Enya engine manual for both the 35-4C and 40-4C are available here as an Adobe Reader PDF format file, in case you might not have one - and if you contact W. Bill Jensen at his engine repair website, it's quite likely HE could get you the original part, or one that can fit your mill, as he's now become the North American distributor for Enya four-stroke mills and their parts.

Hope these linked lines of text can help get you a muffler for your 40-4C mill...

Yours Sincerely,

The PIPE....!!

Or just run it without a muffler. It is probably very quiet as is.

thanks.

I saw that fs_threads.pdf before i started this thread and the reason why i asked if it had a muffler for it is because the pdf stated nothing, so i figured it there was none.

I've got the rear camshaft OS FS-90 as well...!

Dear Murcielago:

The PIPE Here again - for the Enya mills, W. Bill Jensen IS your man, and he is sort of "in my backyard", being in New England - Bill is in CT, and I'm in MA !!

The rear camshaft OS FS-90 has an M11 x 0.75mm exhaust port thread, and can DEFINITELY take ANY muffler hardware meant for the OS FS-91 Surpass, as I've checked that combo myself quite some time ago.

The OS FS-20 MIGHT be able to use the same exhaust hardware as the FS-26 and FS-30, with the FS-30 definitely having an M9 x 0.75mm thread spec, exactly the same as the 21st century-produced Saito FA-30S enclosed drivetrain four-stroke and the currently produced FA-40a also use, and which I both have (on the two small Saito mills).

Hope these tips also help you out...

Yours Sincerely,

The PIPE....!!

Similar to your Saito 40, the FS20 did not use a muffler.

The four engines you mention didn't come with mufflers and mufflers were never made for them. You may find some that will fit. You will have to look.

I have several Saito 45's and a couple each of the others.

The last version of the FS90 had a muffler.

If you look in ht head of the 35-4C and 40-4C you'll find there is no thread! The manifold is secured with a set screw.
