[@wayne-wango-wever8393]

Wow!!! Who would of figured two back to back same crazy issue. Thanks for the video.

[@williamcolon3647]

Great video!! Thanks for posting. Not boring at all. Learned a lot from it!!👍

[@bonzaibarty]

The first carb was a pain but you did a great job! And thank you for the lead on the bear g tip cleaners!! That was a great suggesting!!

[@Tysman909]

That's a stubborn carb. Patience is key I enjoy troubleshooting :)

THIS is why I watch all Leon's video's, there real life stuff. If something goes wrong there is NOT the obvious BREAK in the video where it is edited out. If you do something that should have worked as it was done the right way and it DOES NOT...then what?? These video's show the potential problems that can happen in REAL life and what to do next or try next as he FIXES it.

Just some information. I had the same issues trying to get the seat and needle to hold on my HL63G, off my old McCulloch 250. The gasket and needle rebuild kit that I purchased cost more than a new China knockoff carb. Purchased the knock off and bolted it on, runs great. Too much time wasted on the old Tilley, to just get the saw running.

[@jeffreylangenstein4222]

can relate working on a Tillotson HL63f

[@edcowles6414]

You have more patience than me. That thing would have been hugging the bottom of the trash can.

[@eugenefredrickson8714]

Those Tillies have more gravity and produce a louder thud than say a Walbro, when thrown against the shop door. Need a few parts??? K

[@LeonsChainsawPartsAndRepair]

That they do!

[@bobbynash282]

Its ok lm here gotta rebuild 1 on my old homelite xl super .

Good way to practice social distancing!

[@farmerjackson709]

Well the way I look at it if the part is rare and not made any more it’s worth the few extra minutes to seed if it can be used. If it can be saved then you will have it to fix one down the road. Must be something different other than the colour in the rubber. I had a similar problem with a Briggs carb that also had a new rubber seat that was green oddly enough

[@LeonsChainsawPartsAndRepair]

Damn...green is my favorite color!

[@jayalbertz9756]

Great job Leon, carbs can sure be a pain sometimes! I sure hope this isn't a sign of things to come for me, I have an antique Mercury outboard motor I will be working on sometime before summer. And what does it have in it? A Tillotson and I know it's the problem lol! Take care Leon

[@davidp8563]

Perhaps it is leaking on the OD of the rubber seat? You could blow the rubber seat out of the brass sleeve with compressed air and reinstall using some fuel resistant sealant like anaerobic gasket maker? Haven't tried this....just offering yet another possibility.

[@bonzaibarty]

Leon, may I ask if the engine impulses work the diaphram to pressurize the fuel tank or does the impulses make the diagram suck the fuel in thru the needle and seat?

[@bonzaibarty]

1. I am trying to learn about how the pressurized tank works. Does the engine impulses pressurize the fuel tank and at the same time the impulses work the diagram to open and close the needle to supply fuel thru the carb? 2. If the needle leaks will that cause flooding and or fuel leaking out if the carb when not running? Thank you for your help.

[@LeonsChainsawPartsAndRepair]

You got it! In reality the carburetors are designed to work without tank pressure, but anyone that has shaken up a closed container of gasoline knows that it will pressurize. The inlet needle must seat properly or it will overs-supply the engine with fuel while it is running. Then it will sit there and drain the tank onto the floor when it's not running.

[@bobbynash282]

SOB? Id said that about the 10 min mark.

[@davidgaylord2035]

II think the virus is getting to Leon.

[@LeonsChainsawPartsAndRepair]

Ha! Why do you say that?
