Ive run into this problem SO MANY TIMES from customers bringing me their saws and other 2 strokes...and ive come to INSTANTLY recognize when one runs like this its a fuel circuit issue...and it seems that these "rancher" style saws are very unforgiving to unstable fuels. Great job man...i LOVE how thorough you are in your diagnostics!
Yep, I assured the boss my video recording wouldn't waste time hes paying me for. Pushing the record button is nothing but setting up tripods and such would.
Wow, Scott - freakin’ brilliant! All these times I’ve taken the carb apart to rebuild and run it through the ultrasonic and I could have just pulled the low speed screw to clean out the circuit that way! Guess I’ll give that a shot the next time I get a machine in and it’s bogging. You da man! 🔧👍
Yes BUT, I still like to take a peek inside the carb of most repairs with a running issue. The point of the video was to show what the problem actually was. If I would have put it in the ultrasonic cleaner and then it ran fine, would you have been able to identify the actual problem? While the trick to this repair game is identifying the problem without firing the parts canon, carbs can be funky and sometimes multiple problems overlap.
Watching again. Noticed this time you used a compression gauge and gave a value. Just to dbl check? Great job of using the low screw first, using it to transition to the high. Let. Us know if you ever sell your carb stand with your sticker. Thanks again.
I'm starting to think I need to build carb stands. If you see me using a compression gauge its either because I'm possibly going to do a warranty claim or because the cylinder didn't look perfect.
Great Find And Repair Brother 😀👍🏼 I’ve Also Had Similar Symptoms When a Customer Tries Adjusting There Own Carb and Randomly Turn The High Speed And Low Speed Screws Way Outa Whack I Usually Turn Both Screws In and Then Start at 1 1/2 Turns High Speed and Low Speed 1 1/2-3/4 Depending on Saw and Start Fresh And Tune The Low & Idle Then When That’s Set I Fine Tune The High Speed I’ve Had It Happen a 1/2 Dozen Times Especially The Guys Using The Stihl CutQuicks And I’ve Also Experienced Exactly What You Did and The Sonic Cleaner and Removing The Screws and Cleaning The Passages Saved The Day 😀😊 That’s The Difference Between a Technician and a Parts Swapper You Found The Root Problem and Fixed It 👍🏼👍🏼👍🏼👍🏼👍🏼
I'm finding from watching your videos that it is Really important to make sure to maintain saws that are going sit for a long time...meaning don't let them sit with fuel in them, what do you think is the best way to shut down and store saws? Do you think adding a heavier mix of oil to gas just before you store them would help in this?
I would avoid gasoline for long term storage no matter what additives you put in it. The canned fuels seem to work well for that. For ultra long storage I would just flood everything with 2 cycle oil.
Thanks for sharing your wisdom. Any chance you can go through the oil tank ventilation on a 242? I got oil leaking out from the bar locating pin and I don't know what to do.
This is the first time I’ve seen a carb fixture like that. It looks simple enough to fabricate one out of sheet steel and bolts. Was that purchased or built and does it have additional holes for different bolt spacing? I’d probably tap the fixture and thread a couple pieces of 1/4 round stock so I could just move the bolts to the appropriate locations easily.
How often do you get saws in and there is absolutely nothing wrong with it? I had one come in the other day and all that was wrong is the customer forgot to put the kill switch in the start position. 😮
We get a lot of "chain is locked up" repairs that are just saws with the brake on. Mantis tillers are good ones for having the switch off. Then there are others that I think they just want it cleaned but they aske for a "tune up".
