I am currently working on a plan that calls for four engines. Is it OK if the engines are not identical? I have a pair of .52, and another pair of .61 engines. They are identical pairs. I was thinking of using the .61 engines inboard, and the .52s outside. All engines are mounted on the wing, just like a C-130 would have them. Can this be done with no adverse effects please?

Hi, Sorry I mean SHORT or LONG REACH plug. 69 year old typing NBG. Russell
 Schnozzer 1096 points
Uses a standard long reach plug. HobbyKing #4 plug works great. Short reach glow plugs bring back memories... haven't seen one in years!

Hi, This motor is supplied without a GLO-PLUG. The instructions only say to use a medium to hot plug BUT DONOT INDICATE if is a SHOT or LONG REACH plug. Can any one advise of what to install. Thanks in anticipation. Russell

Does anybody have trouble with the remote needle?
 Schnozzer 1096 points
Your question is somewhat vague... what sort of trouble are you experiencing? The only issue I have had with one is air leaking through the needle valve caused by a poor fitting O ring. The cheap and dirty fix for this problem is to simply place a piece of fuel tubing over the needle valve where it meets the casting.
 Templar 12 points
Vague? I was thinking of buying one and wondered if anyone has experience trouble with the fact that the valve was not screwed directly into the carb.
 Schnozzer 1096 points
I assumed you already owned one and were having trouble tuning the engine... That being said, I have had no problems with using these engines with the remote needles other than the leaning out problems caused by the problem outlined above. In fairness though, that particular engine had many, many hours of use. I highly recommend them.
 Templar 12 points
Thanks Schnoz. I have heard the same in other forums.
 Templar 12 points
Hey Schnoz! I have bubbles coming out of the needle. Will try your fix above before taking the needle apart. I don't have any replacement o rings if it is screwed up.
 Schnozzer 1096 points
That is a common problem because of the "one finger" mechanism that engages the needle valve. It applies sideways pressure to the needle and eventually deforms the O ring, causing leaks. This is a common problem with most engines that use the same mechanism, not just ASP. You can actually remove the "finger". The tension created by the fuel tubing fix will keep it firmly in place.
 Templar 12 points
The o ring was messed up. Chewed up I mean. Looks like it was twisted when it was put in. HK is sending me a new one. I had another needle valve from another engine so am using that in the meantime. Testing tomorrow. Thanks. Something to remember about the finger.

templar you are deasling with asp carbs ...there notoriously poor quality ....the o rings are rubberb not true silicon new engine throw awat o ring replace with ..os quality ..problem solved ..oh put large fuel tubimng over it as well ..they cant cut decent threads at asp
 Schnozzer 1096 points
" There (sic) notoriously poor quality"? I own several ASP's, some that are years old, and have been very pleased with the lot. "They can't cut decent threads at asp", that's just laughable.
 Templar 12 points
Its been awhile since my post. Let me tell you my experience. I started with the remote needle and could't get that to work. HK sent me a new remote valve. No good. Then I bought a carb with needle vale on it. That worked for awhile. Now to get it to run I must crank the needle all the way in. ??? If I use an magnifier I can see cracks in the steel around the o ring groove and the tip. I am about to order another carb, only $13, or dump the engine. I have other size ASPs that run fine out of the box and hundreds of flights later. This carb for the 52 sucks.
 Schnozzer 1096 points
Very odd indeed. I have nothing but praise for my .52. I particularly like the .52 because of it's power/weight ratio. I have about 3 gallons through it now with no problems. One of the lads at my local field had similar problems to yours and he ended up putting a medium p e r r y carburator on his. It is now running perfectly.
 Templar 12 points
Schnozz, thank you. I will look into the Perry. And you're right. The weight to power ratio is what made me buy the 52 instead of a 61. There's quite a jump in size between the 52 and 61 and the power output is about the same.
 Schnozzer 1096 points
Templar: if you decide to go with the Perry, I suggest that you contact Conley Precision to ascertain the correct carb size. I just gave my buddy a call and he seems to recollect that it is actually a large bore carb. I am actually a bit jealous* his .52 really hauls. If mine exhibits any of the carb problems in the future, I think I will go the same route.
 Templar 12 points
I looked up the Perry. The 52 and 46 take the #1100 large bore. Thanks!
