026/260 air box mods

[lauren]

It seemed as my 260 with a bored carb could use a little more air, and the air filter would start to plug up after a couple of tanks fuel. So i made this little set up and so far I'm liking it, I have since added a primer so I don't need to remove the max flow to prime it being no choke.

Let’s see some more pics close up and deconstructed.

Cool. Any vids of this running?

No vids, I was just board one day wanted something to do, been wanting to do this for awhile, just didn't have time, maybe ill run the saw more now that I don't have to clean the filter as much, it was an easy to do job

I think we are all very interested how you sealed up the air filter base to the carb. . the air filter and choke setup have been a bone of contention for me.

The build, filter pic 6 tanks of fuel, made a carb box cover, and used the old filter cap screws to hold the everything together, very easy project

nicely done! I may have to try this with one of my 026's

The primer was the biggest pita but i knew it would be.

How does the filter stay on?
Did you oil it up? Looks dry in the pics.
I'm likin it though...

 

[lauren]

Yes it is oiled with uni oil and is held on by a stud like it is suppose to be.

Very cool.

Dumb question, how does the primer bulb prevent fuel being pulled in via Venturi effect in the intact tract bore?

Would love to see more pics.

The line going into the tank is just inside the tank maybe an 1/8" at most, the hole going into the air filter adaptor starts at 1/8" but the hole finishes with .035, so with a full tank of fuel it will act as a power jet but it only last for a little bit of time and is not overly rich.

 

[smokey7]

Most primer buttons I've messed with had little flapper/Reed valve check valves. I don't think they would pull much if any fuel even with a little vacume on the line.

I used an oem echo primer

Could you provide some pics of how you put the center stud in to secure the maxflo filter? Please.

 

[lauren]

I will in a bit

 

[RI Chevy]

No hurry at all. Thank you

I centered a threaded hole in the filter base I used a 2 inch long 5 mm bolt, threaded through, installed a nut to lock it down, it was very simple to make. Let me know if you need any thing else
