When you buy diaphrams and gaskets, even at the most professional shops, they don't tell you how to set that meter, or even suggest a metering guide for the model Zama carburator you have. Bummer. THUMBS UP!!!!!!!
Thank you!
Great work Tom. Expert knowledge and clear communication as always.
Thank you!
Very well explained and illustrated.
Thank you!
Really good information Tom, top guy for this sort of information 👌👌👍👍

Thank you Barry!
Nice video Tom, you're always so helpful. 👍
Thank you John! I appreciate you watching mate :)
Anytime buddy
Fantastic , thank you
You’re welcome 👍
Good show mate.
Thanks Bill :)
I was taught to place a straight edge over the body of the carb and look for a gap or movement of the lever. I just invested $8.50 into the gauges from Amazon. Thanks.
Good choice well made :)
Another excellent video
Thank you!!
Great info Luke
Thanks Arnold
Nice one Tom
Thanks Al :)
This dude is a master mechanic
Ha I wish, thanks though :)
Thanks!
Thank you for the super thanks!! Much appreciated :)
@@VintageEngineRepairs I enjoy your content. Plus, Tom is the greatest first name ever.
@@haneyoakie14 LOL! I presume it’s yours too 🤣👍👍
@@VintageEngineRepairs yep!
@Vintage EngineRepairs
Could you please do another short on the 200 ml bottles you use with the brass spouts?
I have tried and been unable to find them again in either your videos or Amazon
Sure, they’re Pressol oil bottles in 125mls. I can’t get them here any more, I had to go to the UK to order them!
@@VintageEngineRepairs thank you very much
Question: I can't get any response on idle screw on a ms180c stihl chainsaw, carb has preset (no adjustment for h or l ) I've installed new diaphragms and it only idles high. Won't change no matter all way in or out. I took apart again and find no interferences. Any ideas? Thanks so much for your educational videos
Yeah the carbs on them are really useless. They have an air bleed as a low speed adjustment and no high speed screw. Google search “walbro WT215 carb swap ms 180”
How do you know what height to use when you have a generic carb? Sometimes people bring me a saw that doesn't have the original carb. so I have no idea what model carb came on it from the factory.
They’ll be a clone of another carburetor, it’s just finding out what copy they are. Alternativly, before you remove the lever, measure the height with a vernier!
Hi i just rebuilt a zama c1q s131 carb with a rebuild kit off ebay .
Your videos have been a huge help thank you sir .
My stihl fs90 strimmer starts up straight away and idles nicely at tick over now where as before it was a sod to start and the tickover was all over the shop .
Only problem now is the high speed is still lacking in power and it still seems to be missing ,not running cleanly .
The adjustment on the high speed screw do not alleviate the problem.
I have a new coil and spark plug ,gap is set correctly , the valve lash is set ,new filters ,hoses and tank vent .
I did replace the zama with a very cheap (£14) carb off ebay but it only worked well for a couple of days before it became almost impossible to start , still wouldnt work after i cleaned it and checked the lever height etc which is when i decided to buy the rebuild kit .
Do you think i would be better off getting a new carb ?
Could the high speed screw be damaged ?
Any thoughts would be greatly appreciated thank you kindly
Glad it helped! Very interesting, they often have cam problems and can develop air leaks too. Have you checked fuel lines? Impulse? Fuel filter? Tank vent?
@@VintageEngineRepairs thank you for the prompt reply , it has new fuel lines ,filters ,impulse hose, tank vent ,cam gear and spark plug .
Once i replaced the zama carb with the ebay carb the running issues were gone , i could get full power and tick over and it started easy but the carb stopped working after a couple of days so i rebuilt the zama with a kit and it improved it , it now starts straight away and ticks over nicely but the old problem it had of not reaching full rpm while sounding like its missing slightly is still there ,its like at full throttle the rpm wavers slightly and the high speed screw adjustment wont rectify it .
@@VintageEngineRepairs i checked for air leaks with map gas after i watched your video , no air leaks ,great tip by the way thanks bro
Ahhh it’s probably the limiter on the coil kicking in! They have them to stop the engine over speeding :)
@@VintageEngineRepairs hi i replaced the carb and all seems good now ,fingers crossed lol.
Thank you so much for your help.
Your channel is amazing ,i think once people find your channel you subscription numbers will be huge bro .
Looks like Red Corn Cobs on that Tree!! Are there many carbs with Clip-Type attachment buttons instead of just push-on buttons that contact the metering lever?
Ha! It does doesn’t it 🤣
What kind of tree is that?
@@gadasavideos8564 bottlebrush
I just noticed your edited question kenny! Yes, in fact tillotson use to do exactly that, not common now days, more so on the older engines. The height must be set the same :)
Same with the metering forked end, they don’t always hold the needle! They instead sometimes press up and onto the top of the needle :) again that’s tillotson who use to do that most often!
Question? Could you use pop off pressure to set your needle height?
Na they’re unrelated in that respect :)
I’m 😂it’s just the same with my wife too but we are all good to be together so it’s just not that much to be having it on a Saturday morning and then it’s all the time so we just don’t know when it’s a holiday so it’s a holiday but we don’t really need a break
Sorry mate I don’t have a clue what you’re talking about 🤣
Interesting
Glad you enjoyed it!
What bush/plant/tree is behind you? It is amazing!
I’m not too sure! It’s beautiful isn’t it. Makes a great backdrop apart from the bees lol
You're looking at a Bottlebrush plant, possibly a Kingston Park variety. Wonderful plants that a drought tolerant and amazing bird attractors.
👍
👍
And the link to the metering lever gauges is ???????????
Sorry, here you go: amzn.to/3VVUMZx
@@VintageEngineRepairs Thank you. This was a valuable lesson so I wanted to be able to complete the task next time!
Absolutely :) you’re welcome!
Carburaytors?
I spent too much time around Americans
Thank you, mate
Pleasure! Glad you enjoyed it :)
Beautiful Aussie wattle behind you !! Very healthy !! And great video too...!! 😉
Ha thanks mate!!
Good one Tom ! About that tree I believe they were specifically engineered for kangaroos so they would have a way to scatch their backs yeh ? 🦘 😆
LOL!I’m not so sure, probably more for bees, they kept flying around me while filming. In hindsight it wasn’t such a great place to film! Thanks for watching :)
@@VintageEngineRepairs Itchy bees that's a new one 😆
