Stihl 034 super carb question

[Johnmn]

I think I know the answer to this but I'm gonna ask to double check. I put a carb kit in a Stihl 034 super with zama carb. It won't idle no matter what, the metering arm is about .020 above the carb base. Is it supposed to be flush? I don't have a zama metering gauge only walbro

I THINK the zama metering lever actually gets set a bit lower then the carb body. @Chainsaw Jim would likely know for sure.

Thanks @Chainsaw Jim

Don’t forget to replace the check valve/ main jet
Could be letting air into the idle circuit.

So I put the carb kit in metering arm is perfect and the saw is pig rich. It will fire and run till it floods out then nothing. I swear I keep trying the same chit what am I missing here?

Where are the screws at?

1 and 1 the high seems good but no matter what I do with the low she's fat, like fuel soaking the filter and muffler fat.

Is the needle leaking by do you have a carb pressure tester. Also nozzle could not be sealing

 

[trooney]

Something is letting fuel by....

 

[trooney]

Did you pressure test the carb?

 

[trooney]

Check valve?

 

[Johnmn]

No I haven't pressure checked the carb I'll have to

 

[Chainsaw Jim]

It might be a bad impulse connection, weak pop off, or dirty check valve.

Just a shot in the dark, try running it without the filter cover on. My choke linkage binds sometimes on the cover.

Did you pull and replace the Welch plug on the carb? Just wondering.

Tried that no go thanks though

When you do, if it fails try placing it in a glass jar of water, this will allow you to see where the bubbles are coming from and give clue to where the problem lies.

Well I went through the carb again and I got it to tune but it won't idle for s word. I'm wondering if it's sucking air somewhere? It doesn't want to return to idle and once it does it dies then won't start unless I put it on fast idle. Little bit stumped but I'll have to dig a little bit deeper once I have some more time
