???
I have several older glo engines without mufflers. Most do not have the 2 bolt holes used for mufflers. Where can I find a universal muffler (for Fox .35, Enya .29, Enya .19, OS Max .15, etc)?
As an alternate, is there an easy way to make one? (I don't have welding equipment or skill for that)
Thanks for any help.

Here's a set up for my Veco 35. I believe it was made by "Big Art"

Or better yet, build your own lugs. A little aluminum tubing an some J B Weld. It works, and won't distort your crank case!

That looks really neat! Thanks H^^
Have you done it for something like an old McCoy Redhead .35? That one does not have any lugs.

Sorry, no pictures however you can easily form one in the day-dream motif. ;D
In the home-auto stores you can find the metal rings/hose clamps of all sizes that have a screw system to tighten them up. I find it easy to take mufflers and with some fitting, maybe a little filing, sanding or whatever make it fit close enough to get a tight fit. Pop cans make the best of gaskets, easy to work with and total accuracy is not required.
Now cut the hose clamp at where it will have two equal legs or at least close to such, bolt the legs to the side of the chosen muffler and tighten it all up. You will find many sneaky ways to make things work and the more you play around with them the better you will find just what you wanted.
Kind of like days of old when most RC mufflers were clamp-ons. Works!

Don, No I haven't done any McCoys or the like but it seems to me that with a little care you could get things lined up properly. I might put a small 4-40 flat washer on the backside of the lug. YES I said small 4-40, their are large ones, and small ones!
And yes, one of those screw type clamps can squeze your crankcase if tightened enough to hold the muffler in place.

On many engines, you can drill and tap holes just inside the ends of the exhaust stack. Then, you can make an adapter from aluminum plate, screw it permanently onto the exhaust stack (with LocTite or JB weld, maybe?), and bolt on a good muffler like Randy Smith's CNC tube muffler. H^^ Steve

eBay...seriously, I've bought several classic MAC's mufflers and Slimlines from the 70's -New Old Stock.
