Thanks for watching and subscribing to our channel. With your issue, likely the engine has low compression. Check the compression. For 2-stroke, it's around 90-150psi.

@@Varietech-AU thanks alot for your guidance, just wondering if is it worth to fix up if the compression problems or buy new machine? thanks

Thanks

Need to rebuild the carburetor or replace with a new one. Please do subscribe for your future reference in working your own small engine. Thanks for watching.

Nice one!

Likely your carburetor pilot jet or pulse hole is blocked. Remove the air cleaner assy and there is a small hole (pulse hole) on the side of the carburetor manifold, spray it with carby cleaner and blow with compressed air. Even these hole and pilot jet nozzles are blocked, the engine will still start when you spray directly into the manifold. The pilot jet nozzles are those tiny holes inside the venturi towards the cylinder side. This pilot jet also coming through the tiny holes along the wall of the main jet which could also blocked. Health wise when I'm getting better, I will find another unit which I could demonstrate this issue. Warped air filter is the most common problem with this unit. Pulse hole and pilot jet are secondary issue which you might have. As of now, best is to rebuild your carburetor and there are lots of UA-cam videos you could follow.

@@Varietech-AU I bought a brand new Chinese carby for two mowers and two primer bases. Worked fine on one but not on the other, I would keen for a video to demonstrate this problem. Thanks for the reply.

Thanks

It should work. Check for spark.

Unfortunately a genuine or aftermarket replacement carburetor is nowhere to buy. You could possibly buy a old stock genuine carby from US for over $80USD. Best is to rebuild the carby. Thanks for watching.

The older Makita were built to last, especially the engine part. Note: no carburetor will last forever without rebuilding and replacing its rebuild kit.

Thanks for watching our videos.

Thanks for watching my videos. Yes, I will cover carburetor tuning in the future. This will not be a voice over due to the noise of the engine when revving. Thanks to all my subscribers in 🇨🇦.

Thanks for watching and always get notified for future upcoming videos.

Could be internal blockage on the needle valve, incorrect placement of fuel pump diaphragm or fuel line connection. See fuel line connection at 28:00.

@@Varietech-AU Thank you and I will verify all the above. Mystery is while continually pressing the primer bulb that never fills with fuel, starts a leak somewhere far in front of the wacker housing (motor area), nowhere near the carb. I even tried this with carb detached from intake gasket area to make sure nothing from the carb was leaking into intake chamber and it still leaks somewhere you cannot see, likely from the tank somewhere you cannot see. It drips from the motor housing bottom. Also, does needle valve top hook onto rocker or does rocker just sit on top of needle valve.

@@richh6005 possibly have cracked fuel tank or perished fuel grommets.

@@Varietech-AU Thank you. I will have to further disassemble to reveal entire fuel tank, since I cannot assume there is any reason or other area of fuel tank to have any type of intended opening or connectors, leading to what we both feel could be a crack. Not sure why any grommets would even be located in that tank area, since all hose connections are all in the carb area and not leaking as previously stated.

@@Varietech-AU I have thoroughly cleaned all valve orifices per your video and also ensured fuel pump diaphragm is properly in place. Still nothing ever comes through the return to fuel tank connection even under constant bulb pressing pressure. Is there something else and where in the carb that your excellent removals and cleanings does not address where a possible blockage remains, preventing fuel from returning to tank. Also removed that hose to ensure that return connector was what is blocked and not the hose and when disassembled, that return connector orifice is totally cleaned out when sprayed so it is clear.

We can do the next video with you.

Nothing. If it leaks, replace the fuel hose.

Save those remaining PTs especially now we have the solution and fix.

😁 If I haven't fixed the cut out plug, I possibly suggest to turn of the tap when turning off the engine. 😁

For a change, to fix a small engine outside of Australia. Fixed the last minutes before we left my hometown. Fuel stabiliser might not be available or not affordable. I'm not sure if it's necessary in tropical region. One thing I didn't have a chance to adjust the throttle for correct voltage and frequency of 220V 60Hz.

Thanks. It's a great holiday but still I did small engine repair overseas which I'm going to upload next. I brought with me all the different carburetor gasket and diaphragm kit for Trimmers and Brushcutters just in case someone ask me to repair their unit for free. It's a mix of holiday and repairs. I spend half of my holiday is setting up my brother's 10 units Internet Cafe, upgrading SSD and RAM and installing games and repairing his gasoline/petrol generator in Leyte. When I was in Davao, I spend time to fix my brother-in-law's 500W audio amplifier. I'm now in Sydney. Yesterday I did repair on Victa Tilt-A-Cut with Mike from Narrabeen and will be uploaded next.

@@Varietech-AU Good to hear 😁

You're welcome! Thanks for watching and subscribing to the channel.

Sorted!

Well done! What did you do?

@@Varietech-AU It ended up being the air filter...I started it up without it and after that it seemed fine once re-inserted
