McCoy .5 parts

Sorry i ws tring to get them to download from mt camera ? here is fr my phone >

I have to check my McCoy stuff . Might have some thing that will work . I have the Diesels but no glows but most of those early glows and diesels used similar needles . Got to go check some old parts . Maybe a Wen Mac needle ass. would work .

Thanks for taking the time to look . Eric Engine has Great compression and would love to run it .

Found some needle valves . Tried them in one of my McCoy diesels . They all seem to have the same thread size but the tips of the needles very a bit in shape and size .I think a Wen Mac , Atwood , or Holland Hornet needle might work for you . You might consider pressing out the whole assembly and replace it with one from a donner Wen Mac . One thing I remember about these early .049's is they leak air around the needles and need the fuel tubing seal or one of those little black needle seals that Cox engines use . I will try to measure the thread size for you . You might be able to make a needle from a small screw .

Ok Just checked some needles and this is what I found out . The best that I can tell my McCoy diesels use a 1-72 N.F. tread as does the Pipe bomb engine with the White tank ,the Wen Macs , the Atwoods and Wasps and possibly the Testor engines . The tips are tapered but blunt on the end on the McCoy , the rest have a cone shaped tip . I could not tell you what the tapper is on the needles but I think that they would all work to some degree ,they are all very close in design . Hope this helps you in your quest to run your McCoy Let me know if you can't find a substitute needle .

those will work, does the glowhead work or are you gonna tap it for a short glowplug?

NO Mark it don't , just tried it And its tight as the devil too . OK Mike i have Atwoods and that's not going to work Had some Testers but i think i got rid of all them ,, Wen Mac maybe i will have to do some digging into my onehellofamess Thanks again that is pretty much what i needed to know is a interchange possible , and a press is not out of the question , i got a wild hair there .

WOW i had one in my display case Wen Mac roto spring long brass (only One ) now for the glow plug ?

I think the 5 had the insert type of plug that may be hard to find. Good luck on that one .

Hey, the one time that something interesting and affordable comes up locally, and I don't have any use for them

lol, i just woke up and realized or think that glowhead is actually an Atwood 'Shriek' head, that somebody attached...if that's the case (or head) you might be able to use an early Wen-Mac head and a short glowplug???

Wow Thanks Mark , The Wen Mac i took the needle from has a insert that may work , i haven't had time to take the head off yet maybe today . I see Meco has the Shriek heads in stock 9.99 if things don't work out . Of coarse it would bee the next of never getting one LOL
