I don't use that one

Right place to order, but its the one above the one you showed, #615-912 as its slim and it will fit into the neck of the durbo tank.

The one you show is 615-913. The vario one is the same or looks the same as 615-913, except that its Vario branded and it means they put a 1 in front of the 2 for price so instead of $2.99 its $12.99, (just looked, no wait)...they put a 1 in front of the 2 and then they added the $2.99 and put a 2% Vario tax on top of that for a whopping $16.24! Woo hoo Vario!

Man that's being mean to the customers...

Raja, you think Vario is the only one charging a premium for their name?

I am still wondering why you put any filter in your heli tank after you proved it could cause trouble. Filter your fuel before you put it in the tank and then you don't need one in there.

I proved the stents one is bad and was causing me trouble. I really do like the felt one as it absorbs fuel from fuel splash in the tank and works better in not letting the engine lean out during 3d maneuvers with less than 1/3 tank. Lets just say its good to the last drop even though I don't push 3d below 1/4 tank. Oh yeah, and it prevents that first flip "bubble cough" if I may add

P.S. No matter how well you filter the fuel before you put it in the tank, something will manage to work its way into the tank, from as simple as your connector picking up dirt. Its always good to have a filter, though in gassers the carb has a final screen in it that will save you. The idea of the felt clunk is fuel pickup, and the filter is quite a nice added bonus. (this way you don't have to clean out your carb internal screen).

Raja,
Its not bad, it just doesn't work in sub freezing temps like you found..

In fact it may work to good since it pickup smaller particles...

Some of the felt clunks can do the same like the one with the clamps around the felt that walbro makes...That thing will plug up in a heartbeat because its been so compacted...
The one reported earlier in this thread is the best felt clunk..I'll agree .
The prudent thing to do is to back flush as part of maintenance any clunk you use...Its good practice..

Thanks Bill :)

You should try the felt one if you haven't already and give your opinion. I felt that the ceramic one pictured in this post (the one that plugged up on me in the winter) is more restrictive in fuel flow even when new compared to the felt one. Ever since I put on the felt one the engine has run well and I've lost the hickup on the first flip that I used to get -- I was watching my video today (someone asked me about it) that was taken 2 years ago when I was using the stents clunk and you can hear the engine stumble in the first flip. So glad that problem is long behind me now due to better fuel flow

Ok, I gotta go, back later. I need to do something for Nick!

You didn't read my post, I agree that its a very good clunk.. The clunk comes with the R/C engine and probally the best Walbro makes..I use it in my acrobatic...Its a very good clunk..

I did read your post, guess I didn't understand your English. Let me go through it again:

You're talking about the stents one here that I don't like (ceramic)

Quote

I think you're still talking about the stents one, it picks up smaller particles meaning you're saying it gets plugged.

Quote 
Some of the felt clunks can do the same like the one with the clamps around the felt that walbro makes...That thing will plug up in a heartbeat because its been so compacted...

Here you're saying from what I decifer that the one I like (Walbro) with the metal clamp is even worse than the stents...

Quote 
The one reported earlier in this thread is the best felt clunk..I'll agree .

Which one? Stents or Walbro at Jschenck shows stents, Aambrose links Walbro... Sorry to me sounds like you're beating around the bush I'm not sure which one you're liking and its not obvious to me that you liked the Walbro clunk or even tried it. But no worries, its all good to hear you're on the same page!

Aambrose, I use (A), (B) is too fat to get into the Dubro tank.

Bill, do you like (A) or (B)? If you're flying Vario then it probably came with (C) which is equal to (B).

B and c are the same, there both made by Walbro...So B you can buy locally...B is my favorite...
I have found A to be to compacted in some cases, note (some cases)... its still ok, but when fuel hits it, the felt tries to expand and it now gets tighter...

I'm sure there is a reason they clamped it that way..Maybe even knowing it would get tighter, and able to catch finer particulates.



The Stens is a plastic type porous material... If you could get a True ceramic filter, it would be the best hands down...They don't make them anymore, to bad...

If you really want a ceramic one check in a high-end pet store. There are ceramic air-stones that people use for UG filters and protein skimmers. They may work for you.

I have a question, I understand what is meant when you use the term 'hesitate', but what do you mean by 'stumble'?

Thanks,
David

Now thats interesting, thanks for the tip...

On the difference of words, hesitate is probably one quick delay or skip in firing. Usually associated with lean....

Stumble is more like rich, and misses several times before clearing into a better 2 cycle run ...

I've always seen plastic fittings on the stones sold in pet stores, but then again I'm not very familiar with those. I have some that we just bought for our daughter's aquarium and they have plastic fittings. Will those hold up to gasoline? Wait a second...it says on the back of the package, "Not to be used for fuel filters in gasoline powered helicopters". Just kidding!

Since we're talking about stumbling and hesitating, what is considered a "sag" or a "bog" and what causes that? I'm mainly talking about when you are throttling up slowly with an already warm engine and it "sags" a little (less power).

John

Thanks!

I would say it's a tad lean... on the L needle,, Or a Hot engine, XGM/VGM

I think we are putting to much emphasis on coming up to speed...what is important is what is it doing after it gets up to speed....These engines are designed to run wide open...Some carbs will allow different ways to come up to speed....

The stock air cleaner on the 26 will effect the 26 much on coming up to speed...Most of the time I can just take the filter out, and the engine will correct itself where the pilot was not lean enough on the low needle...

Burned another tank tonight. Now my case temp right under the carb is in the 160 range, fins above the carb are in the 220's but I was getting 280's on the fins above the exhaust port. Seemed to hit in the mid-250's shooting into the fan shroud. The L was so rich that it was smoking just idling almost like a nitro engine. No sag on 10 second straight up full throttle climbs. This is with the Belray H1R oil at about 3.5oz/gal.

I'll be interesting to see how the Amsoil Saber Pro compares.

Here's the plug - can definitely smell the H1R, much different than the Lawnboy.

Assuming there is nothing mechanically wrong with the engine or fuel supply it means your needles are not set right. Many times it can be a fuel starvation problem or an air leak. The question that needs to be asked is did the engine run correctly before, and now it is sagging without any needle adjustments? Or, have you been playing with the needles and now it has this characteristic? The answer to these two questions will point you in the right direction.

If the answer to the first question is yes then the very first thing to check is filtered clunk, then carb screen and the third is flapper valve on the pump. If the answer to the second question is yes then start from square one on the needles. That is all I can say.

Sniff, sniff, I smell something burning. If your low needle is so rich and it doesn’t hesitate when you punch full throttle it could be that your high needle is right on that lean breaking point. That’s why it is so crucial to have the high needle right before you set the low. On a hot day you will smoke it … Beginners curse. Synthetic oil will allow you to run lean for a short period and then it will $hit the bed all at once.
