Pocket bike carb

[Motor Boys]

Hey guys I finished the conversion and install of a pocket bike carb on my bike today. all is running smooth with a slight difference in power, any tips on a way for me to get the most out of it?

It doesn't look like it's any more complicated (or different) to tune than a stock HT carb...

It doesn't, does it. I got in a shipment of these to try out, but I have not had much expereince with carbs, so I thought I would ask.
Thanks

any tips on a way for me to get the most out of it

I would check for air leaks on that welded manifold it looks a bit suspect

cheers

Does it have any adjustment screws? Air bleed, or mixture type?

I does look different than the stock carb, but I can really tell what's going on there from the photos.

How many jets, or circuits does it have?

 

[Humsuckler]

its a flatslide carb, with a single main jet that the pilot and idle circuits run off.

so, i dont imagine you can really drill it out, becaue you would have to in turn drill the pilo and idle holes as well. 3 holes, one jet.

i took it off. CNS is the way to go

Can I have it?

 

[Humsuckler]

nah its going back on my pocketbike lol

the intake I did in about 2 min. , I have since built a better one. All is working well, just doesn't have anything to adjust airflow or anything else. Just a waste relly. It does look better but thats it.

That's the bugger with the SHA's, real deals or the clones...ya get one jet, an idle screw and that's about it. I got a couple here collecting dust.

A PHVA or PHVB clone would be the way to go...

and speaking of working well, my engine is coming back to life from its 30 clicks running on pure air and gasoline fumes..... phew.
the pk80 really is a good little engine lol

that carb came with my motor as "the new 2009 carb " wonder how it will go with a reed valve

How far is a "click"?

I wonder if the pocketbike mufflers can fit Grubee/HT 2str. I put a briggs copy box muffler on my ht in lieu of a expansion muffler (hauls ass but loud), although its cocked at an angle.

I have thought of trying to find a 2hp briggs edger carb. They have a float, idle screw, and maybe mixture screw, and good venturi design. They have a butterfly valve that you can operate by a linkage or cable pull. There are tons of good filters and boxes for them if you have room.
