Carb Guru? WJ-69 and Clone comparison

[Poleman]

Dave, I was having the issue with the c3m copy, but wondering if the issues could be similar.

 

[Moparmyway]

I've put 2 of these on muffler modded 066's and haven't had any problems.

 

[Cut4fun]

I've used Dave's 272 carb replacements on a run hard put up wet firewood friends saw. No problems.

As you should IMO. I go through and check all fasteners before installing. Dont want a loose choke butterfly screw coming out etc.

I have 3 of the 69 clones,at wfo they might make a little more power than a oem one but they hunt at a idle. They idle ok but it drives me crazy to here it going up and down.

I'm no carb pro so I'm sure someone can get that out of them.

Do the clones fit correctly at the air filter snorkel and impulse lines? They don't look like they line up the same with the Walbro.

 

[Moparmyway]

Same fit

 

[Fish]

Look at the left edge of the snorkel in relation to the left carb stud hole.
They look the same?

 

[Definitive Dave]

Its a camera angle thing I was really close trying to use the flash to illuminate both carbs and so the image is a little distorted but they line up perfectly.
The impulse and fuel nipples are the same size, just different needle configurations and when I looked inside the main jet is removable on the Wally but cast into the body on the Zama.
I was hoping to be able to swap out the oversize jet in the AM carbs like we do with the 69, but no such luck
If you know carbs and have a way to measure the orifices on these things shoot me a PM please.

I realize that pic isn't much better, so give these a gander ALSO - FUNNELCAKE!!!

 

[dall]

i love funnelcake

 

[Fish]

Is that an OEM funnelcake?

 

[Definitive Dave]

OEM Cinnamon Funnelcake - rare as hens teeth, only made a few of them, very valuable

 

[Terry Syd]

If you have a set of the micro drills you could size the jet very easily, then drill the other jet to the same size. (or the size you want)

They don't cost much and are a great addition to the tool chest.

 

[Definitive Dave]

micro drills - are they metric and standard or drill sizes?
I have a good tool store nearby if I know what I am asking for.
Is there a range of sizes that is likely to be useful for this?
thanks in advance for the sage advice
Dave

 

[Terry Syd]

I have a set in both metric and SAE sizes. The two different sets allows me to tweak the jetting just a bit finer.

Lots of guys on the forum have a set that they have gotten from Ebay. You will definitely need the 'pin vise' to hold the drills - and always check your sizes with a micrometer/calipers before using, they are so small that they can easily get mixed up.

That oem funnel cake looks fine, like a big crispy warped cinnamon doughnut thingie. I know what missy has on her agenda today...am funnel cake. Fork the chincy carbs, I want funnel cake!

 

[Jchin]

Mr DD, those funnel cakes looks delicious........

 

[Chainsaw Jim]

Look at the left edge of the snorkel in relation to the left carb stud hole.
They look the same?

Just swap out the plates and It'll be good to go as far as alignment.

 

[Moparmyway]

There's no need to swap the plates, everything lines up just fine

HOORAY OEM Funnelcake!
