I am surprised at your comments. I have four Veco .19's and all are well made. I was impressed with my first one because from the box it started first flip. That was ~1970.
I do not have any of the MECOA ones.

I think I have three and love them. Real power for their size. I have Mecoa mufflers but I don't know if they are new old stock or reprods.

The Veco 35 was built with a full floating bottom rod bushing. The piston/rod is installed in the block with the bottom end over the crankpin and the sleeve slid into place. The bushing was then inserted and the rear cover was bolted down, holding it in place. IMO it was an excellent construction method, as it allowed the pin bosses in the piston to be much closer together at the top of the rod, lessening the bending load on the wrist pin. I expect this is what you have.

Call the guys at Mecoa.

The old Veco 19, I have didn't run right out of the box. There was no taper in the liner, had no compression, bronze bushing was turning in the rod and I had to almost destroy the crank getting the rear bearing off. Nicely made parts with strange clearances. I'm not on here to bash the good old Veco 19, I just wanted to know if I buy the currently produced engine will it be a little more consistent in quality.

That is completely amazing, all the Vecos I have and have had were great. If they had a vice is was that they took forever to break in.

And the original Veco 29 had a wonderful 4-2-4 break, although we don't use that much anymore.

Here is some info. They are made like the originals:

Wow, Tom, thanks for posting this. I acquired an old Veco 35 a few years ago that had a lot of slop in the bottom end of the rod, and this would explain it. There must be a 40 thousands difference between the hole and the diameter of the crankpin. I never thought an engine would be made like this. Now, where in the world would I get one of those bushings? Or is this a good excuse to get a lathe and start making my own parts? Hmmm...

Talked to Mecoa and they say the Veco 19 is completely made in house with all new parts. The RC version with the muffler mount holes is not available so you have to drill your own holes for an HB muffler and crossbar.
MM
Funny, I remember when some CL guys were filling-in those muffler holes with JB Weld.
Is it the .19 size HB muffler?

I have 3 19 BB's and 1 bushed 19 the bushed engine has a floating rod bearing and runs very well I have one of the HB muffler setups and it fits like a glove. All 3 bb's are converted r/c motors and have the exhaust butterfly holes the HB muffler really tones down the howl , I did have to add one .005 head gasket and it likes the muffler a lot better now .

Is there any obvious difference between the current MECOA version and the original? I bought an unrun one a year or so ago, but have no idea just how old it is. It has a serial no. (0011459) on the LH mounting lug. It seems well-made, and took a lot of running-in.
It's a very loud engine and I didn't have an original muffler for it, but found that the common Enya 15/19-size muffler is easy to adapt (by grinding away one or both of the little locating ridges) and seems to work well.

On that K&B link there is a K&B .61 CL motor that I have never seen or heard of before. I have one of the old K&B .61. It is listed at $110.00

Mine is 0042205 and is definitely pre mecoa so, I'm thinking yours is too. Judging from this thread I don't think they're flying off the shelves and the man I talked to said you can't tell the difference between new and old which makes me suspect they still have a cash of parts they're using.
As far as I can tell the MECOA version doesn't have the dogbone for the muffler attachment, the holes in the case for the dogbone, or the muffler itself, so I don't think it's all from a cache of original parts.
It's a great engine and the near-equivalent of the 20FP in terms of overall power (although not nearly as steady), but without some sort of effective muffler I would be hesitant to get one.

These were run in Clown Racing at Brodak. Competitive until the last few years. Powerhouse deflector piston engines. (I think they are loop scavange.) In the last couple of years they have been outclassed by newer engine choices. Could it be LA15s and FP15s plus some other exotic choices. I forget. I have seen LA15s turn 22,000 when propped right and broken in at a scream. All in all Veco 19s are very interesting classic power. When Veco 19s were more competitive in Clown, I know a flyer who sent piston liners out to be chromed. He won Clown a number of times at the Big B.
