- My 2 Stroke engine is down on power and air filter is wet with gas. How can I fix this!? check the spark arrestor AND the exhaust port for carbon build up. Clean and or replace. this will increase your power immediately. if the rings are worn excessively, depending on your skill level, replace the rings or ring. Good Luck
Congratulations Sir !!!
You've analytical solved the problem. It's not a theory, your analysis proves it to be a fact !!!
Most trained experienced mechanics haven't figured out what you have. VERY WELL DONE.
ALL THE BEST TO YOU AND YOURS SIR.
Best compliment of the year! Thanks for taking the time to comment. I appreciate you.
Great vid man. It's easy to get into the weeds with how these engines operate. I sent this to a buddy I was trying to explain this to. Good explanation without getting overly complicated 👍🏻
Thanks for taking the time to comment. I appreciate you.👍
Thanks to this vid I've diagnosed and remedied the issues that I was having with my 2-stroke weed-wacker unit; huge build-up of carbon deposits restricting the exhaust port. Gracias amigo! 👏🏻
Nicely done. Explanation done in a flowing and timely matter and information coming across at a pace where I had time to take it in before next steps. Dont see that to often and becomes a quest in search of how you did this video. Outstanding.
Thank you Dave. I appreciate you. 👍
Fantastic presentation and explanation! Kinda new to the chainsaw “repair” world and these help a great deal! Thank you, sir!
You are most welcome Bud. Take care and stay safe my friend. 🍺👍😁
Thanks! My back pack blower just all the sudden wouldn’t start and had a wet filter.
Having this problem, I understand now, thanks to your excellent and easy explanations. I know now, what to do !
Thank you very much !
Thank I have that problem
I especially liked info where cylinder or ring wear taking place and the outcome of that vs other areas that most people get lost in a vicious circle of outcomes not helping, and missing what could be the issue, as some people dont understand the theory or dont think of it.
I've asked about this, he's referring to a question I've asked. A coworker owns an srm225 Echo straight shaft trimmer. No power at full throttle but a small amount of gas spits out of the carb.
I have an issue about the hose that connected going out to the air filter , when i start the engine , air pressure comes out including gas or petrol, It wasted the gas, at first i thought it comes out from the carborator but when i remove all the air filter and foam there is no wet fuel at all. It came from the small hose from the engine block.
I replace new carborator but still the same. It wasted my fuel inside the air filter chamber
Cool thanks
Excellent explanation and illustration ! I have these same symptoms after replacing the piston and rings on my Husqvarna 145BF backpack blower. My connecting rod had a small piece break off and the blower stopped immediately. No damage to the cylinder and only to the bottom of piston at the connecting rod holes on piston. I made certain I faced the rings in the correct direction also made sure the split in each piston ring was positioned on its locating pin. I wonder if I could have installed a ring incorrectly or there was damage to the cylinder that was not easily seen ? This blower may have 100 hrs on it and always used Husqvarna 50:1 oil mix.
Just asking is it possible that you installed the piston 180° off? That would definitely cause a ring to snag in a port. Just asking
@ulitepilot aka Zombie Dave Good question but I did turn the arrow on top of piston in correct direction towards the exhaust port.
Love the schematics
Your explanation of the effects of ring wear and carbon build up in the exhaust port were pretty good. The discussion of the sacrificial seals on the crank seems out of place. Would leaky seals contribute to the problem of fuel mist coming out of the carburetor?
Congratulations, you got me thinking early on a Sunday morning.
Hi Dave, sometimes when you are making a video it's just whatever comes to mind comes out your mouth. Lol.. leaking seals are worth mentioning because positive pressure in the crankcase can put out oily black residue out between the journals and the seals.
Just found some gas on my air filter in my piaggio zip, when its cold feels lazy accelerating.
Just wanted to say hello and let you know I was still watching you
I been checking on you too my friend. I hope all is well with you.
groovy
My issue is I need to put gas on the air filter or the carb won't pull any gas from the bowl at all.
Is there a question in there? 2 stroke? 4 stroke? Mower blower chainsaw? If you're looking for assistance then ask a question. I may be able to help.
@@ZombieDaveAZ 2 stroke 90cc big bored to 100ccs, It has a high airflow air filter instead of the airbox and I wrapped it in two shop towels for restriction which helped a bit, but it doesn't idle and it still needs gas on the filter here and there
Any idea what causes blow back when it’s on a new top end? Ring end gap point is good as a new install. On stihl 028. Could the after market have a port timing issue?
Hi, did you find the answer? I have the original top end, and i'm getting blow back. It's an old engine but i still get 155 Psi of compression, so rings are probably ok?
Check for carbon build up in the exhaust port to where you can actually see the piston. I'm thinking that's why you have such great compression along with the blowback. Also try running it with the muffler off and look for the blowback. By doing these things we are trying to isolate the problem. I hope you know what I mean brother.
facing same problem but recently i did top end build compression is perfect its an old Japanese 80cc yamaha two stroke facing low rpm bog also but pulls great on high rpm..plz help i am totally messed up!!
Hello my friend. I'm assuming this is on like a mini motorcycle? Does it have reed valves. Is it a slide carburetor like a kehein? You need to give me more info to help you. What else besides cylinder and piston did you do?
Hi. great video, I'm having that problem on a Ryobi BP 42. Even though I checked the muffler was unobstructed, I will run the engine without it to see if anything changes . Here is the video of my BP 42 blowing fuel mist out the carburetor air intake czcams.com/video/CXDZ9vKdw4Y/video.html Thanks for the explanation.
You have ring wear if all the ports are clear. This is like replacing a rear main seal in a car. It's $1200 of labor to replace a $9 part. Check your compression with a gauge and see what it says. New would be around 150psi. You're prolly down to 100-110. Running 40:1 mix will help with this but it's a temp solution. Replace the rings is the answer.
@@ZombieDaveAZ Thanks for your advise and quick reply. I will order the parts, open the engine again and change the rings
