Love it when it actually means something. Have often found that unless abused, (reintroduce public flogging?) a Fox motor would perform as desired.

Up here it frequently comes posted in much smaller format that it was "Assembled" or "Packaged" in Canada.

The phrase I find most comical; "made in the USA with globally sourced components". "Assembled" and "made" are very very different things. Like ABC and 'ABC Type'.

Anyone know where I could find manuals for these engines? I emailed Sharon but haven't heard back yet and forgot to get ask about a manual for the .40 and .50. Certainly not detrimental to running them but I like to have something to keep in the box should it ever need to be sold. (I'd be dead if any of my engines were being sold).

Yeah, then there are the phrases like "Designed in the USA" or "Designed in America". I once saw a "Engineered in the USA" too. There was a Goped that had a Chinese made engine that stated it was "Designed by Mitsubishi" too. That cracked me up.

Here are some of the instruction sheets that came with the different engines. The .40, .45. and .50 large case engines all used the same instructions.

I am a wood flooring installer/finisher of 15 years... Never had I laughed harder when my distributor brought in a new prefinished product. On the box beside the branding info was "Designed in Missouri, Assembled in China". The wood is grown in the US, shipped to China to be dried, milled, assembled, and finished just to be sent back. Sad.

Many many thanks Earl!

I know about these things, I work in the auto industry. There really is no way to claim something made in the USA 100%.

I heard that there are Chinese wood processing ships that pick up the raw wood in the USA, drive out to sea, process it on ship, and then dock back to the US to sell the final product.

I believe that for some brands. Of the lines we carry, most of them are made in the same factory despite having 3 or 4 different brand names. They lost my interest in prefinished/engineered stuff when they went from birch plywood substrate to a eucalyptus plywood substrate. The veneer delaminates away from the resinous Eucalyptus wood causing product failure. The Chinese don't have factory finishing down well either; it always peels and flakes up.

Some of the stuff from the local hardware chains is made in china. I bought some wood dowels like that. My house has the old-fashioned hardwood floors, no laminates allowed in my house!!!

Going back to engines, I have a weakness that makes me build an airplane for every engine I have. I don't have the ability to put engines in a box without an airplane designated for it. It's a shame, really.

Theres no replacement for the beauty of old growth hardwood. The reclaimed hardwood market is hot right now in light of the whole 'ECO' craze.


I believe in the philosophy of "the time to buy something is when you see it". I may not need it, but when I do it'll be right there. I'm a bit like Jeffie8696; I like to have the option of switching engines in a given model just to switch it up. They say 'variety is the spice of life'. I do bench run my stored engines from time to time. Keeps them loosened up and it's pleasing to my nitro burning senses..

I ran into an issue I've never encountered before with any engine. Running my .40BB Std. engine using a 10x5 APC, FAI fuel, and Fox idle bar plug, I got 13,800rpm peak but could not get it to idle or transition well at all. The idle mixture needle was closed and was still quite rich and couldn't hold an idle below 4000rpm. What would cause this? It ran really nice and smooth on top though.

Sport_Pilot

I do not know what carb you have but if it is one of the idle bleed carbs then the mixture screw is a air bleed screw and fully closed is the maximum rich setting.

1QwkSport2.5r

It's the square neck MkX carb. Two needle, no airbleed. One needle is black/brown in color, the other is silver in color. The black one has a blunt end and the silver one has a longer taper. The black needle is in the idle needle holder; silver high speed. Could the needles be reversed?

1QwkSport2.5r

Here are a couple pics of the carb and needles. They are in the right holders but I suspect the low speed needle to be incorrect for this carburetor. Last picture shows the tach about 400rpm richened down from peak.

It looks like it may have been "Adjusted" as the knurl looks like its been removed as well.

1QwkSport2.5r

I'm not sure if it has. I pulled the needles out of my Fox .19 and those needles are similar to the .40 needles in respect to their basic shape but the long tapered needle was in the idle holder and the stubbier needle was in the main needle holder. The knurl is likely worn off from the detents and perhaps due to the previous owner constantly adjusting it. That carburetor came off the .40 Mk V from 1983; a single rear bearing engine.

I'd back the LS needle out at least a turn and lean the HS needle 1/2 turn & try it. Keep in mind that these things run on the LS needle until about 3/4 to 7/8 throttle.

Doesn't work. Tried it and many other combinations. I am going to try reversing the needles and trying again. With the idle needle (stubby black) seated and throttle set low, fuel spits from the carb like its snuffy wet for a backflip start. I

That idle needle looks awfully blunt. Could the end of the spray bar be distorted from jamming the needle against it?

CR

1QwkSport2.5r

I don't think so; the end of the blunt needle is the same color as the rest of the needle. As I said in a previous post, the needles in my Fox .19 I had nearby has similar looking needles but they were in opposite holders. When I got this carburetor it was all disassembled so I installed the needles where I thought they should go. If I get time today I'll try switching needle holders/needles and see if that makes a difference. I'll take a photo of another unmolested Fox carb and compare.

1QwkSport2.5r

Fox .19RC with MkX carb.

Sport_Pilot

I believe the main is blunt now that I recall. It would explain why the idle needle has a worn detent and the main does not. Fox may still have needles BTW.

1QwkSport2.5r

I think it's as simple as reversing the needles and trying it again. AFAIK Fox has no parts at all.

earlwb

Well I always thought that the short needle was the low speed one and the long needle was the high speed one. But my brain could be off in that regard though. It won't hurt anything to reverse the needles and see what happens.

1QwkSport2.5r

Switching the needles goes against the grain, but I remember reading somewhere someone else had the needles backwards in a Fox and it wouldn't run right. That's why I pulled the needles out of my Fox .19 just in case there's a correlation. I have my 46bbrc abc with me but that has the EZ carb. I'll look at the carb on my other 40 when I get home from work since it also has the MkX carb.
