BJ's Model Engine Service looks like it's closing soon...


Dear Fellow RC-Groupers:

The PIPE Here...I just spotted the news from what's apparently New England's only model engine repair place, that due to the owner's declining health, BJ's Model Engine Service in Connecticut seems to be closing its doors soon......

...the sad news seems to be quite recent, as I do have a "donated" Enya 46-4C four-stroke mill thst's in serious need of an overhaul Bill Jensen is said to have been an "Enya specialist" to some degree and I was hoping, once my finances had cleared up a bit after 2017 got here, to have sent it out to BJ's for the repairs it needs...

...so, with BJ's reportedly "going south", can anyone recommend a reputable, alternative model engine repair firm, that's "not too far" from New England, by any chance?

Thanks in advance and Yours Sincerely,

The PIPE....!

The Enya is not anything " special". I would think you could do your own repairs. I don't know of any business that specializes in Enya. I do all my own repairs, but I'm a motor guy. If you can't find anybody I could do the work for you.

Enyas are pretty easy. I am rebuilding two Enya V-twins and even after being crudded up for years, the parts slide apart with some heat. Very nice machine work in an Enya!

It's that "heating" part that I'm not quite equipped to do myself..!

Dear kenh3497 & jhaywood:

The PIPE Here again...firstly for Ken, thank you very much for the offer...as I've had ONLY four-stroke mills for a generation now, things like valvetrains (everything from cam-to-valve, tappets, springs, spring-keepers, etc), induction & exhaust systems (except rethreading an exhaust port for repairs!) and drilling/tapping threads for camshaft compartment breather nipples are all things I've worked on, or look like they could be worked on, with the right setup at home (something I don't quite have at the moment).

For jhaywood, where I really do NOT have a readily-usable "heating" setup at my disposal of any sort...outside of using my retired mother's gas oven (and only if I'm not going to smell it up!) I'm not really set up for such procedures like bearing changeout, removing prop-drive washers, cylinder-liner replacement, etc. that usually require heating at some stage. If you, Ken or someone else did have that sort of experience, I could easily send whatever sort of work that might require "heating" out to a second party to get it done, or to whoever would have the free time (and the proper sort of experience) to do it.

I'm not really in any sort of "immediate rush" to get the Enya 46-4C overhauled as yet, but I'm mostly trying to find such alternate sources of "engine repair knowledge" to get ready for when I would need to get it done.

Thanks again and Yours Sincerely,

The PIPE....!!

P.S. For Enya's four-strokers, Ken Enya's page HERE is something I 've got bookmarked, so at least the parts look to have an easy source to get 'em from.

I can repair/rebuild your engine also. I also have several rebuild videos on my YouTube channel on Enya engines.

Those ARE nice videos you've got there...


Dear dmrcflyr2:

The PIPE Here again - thank you as well for the offer, and I'll certainly keep it in mind...

...and those ARE some nice videos on your RCG blogpage!

Both my smallest (HP VT-21) and largest (RCV 120 SP) displacement figure four-strokers use "rotary valves" for their induction/exhaust needs, and I've read that a SMALL quantity of castor oil in the lube content of the glow fuel for engines of that type helps to seal the cylinder head, through castor "varnish" accumulation over time.

Also, Clarence Lee, in his review of the HP 21 in RCM's four-stroke engine book from the mid-late 1980s (which I've still got), said he couldn't get the idle on the 21 that he was testing, below 3,000 rpm...that could easily be from it being both a relatively new mill, as well as being such a small displacement one...

...but it could also have been from what I've been suspecting, that the cast metal parts of the induction tract of the VT-21 could be preventing a decent airtight seal, something my example would get a real good checkout of before I ever fire it up!

Again, thanks for the offer, and I'll be keeping that in mind...!

Yours Sincerely,

The PIPE....!!

3000 sounds high but recent testing of my marinized OS 4strokes had idle of around 2500 and that seemed pretty slow. Never owned an HP21 so can't comment otherwise.

If heating is your problem, and your old retired mother does not want you to smell up the oven, get some kind of container with a non-sealing lid, anything really, like a cookie-tin or an old pan, and place the engine inside it before you put it in the oven.

Alternative, if mom is still worried about smelling up the oven, use a flame distributor and a real low fire, and simply put it on the cooking range like you would any pan....

As long as the flame is not touching the tin or pan, and you don't rush things (low fire), you'll be OK....

If all else fails, you might want to try and borrow one of these electric hot air blowers they use for paint stripping or the likes. Can't imagine you do not know a single person owning something like that....

I have a HP-25 VT. Idles way lower than 3k rpm. Beautifully engineered lump - although its definitely a lump, heavier than most 40 size 2 strokes, and not that much power.

I've used a blowtorch (gently, and very carefully) to heat a block up enough to tap out the bearings. A sealed pot in the oven is a better answer though.
