I like the paper trick for the gasket application 👍🏼 I usually use the corner of a small plastic bag and cut a small hole in the end . Check your piston ring gaps are correctly placed 👍🏼

The best video on a small strimmer engine well detailed help me a lot many THANKS

Чётко .Без лишней болтовни и всё понятно .

I think mine i hv to change those valve guides! I was shocked to see no valve seals thr in my gx31. Nice video. I watched yyour video just to confirm GX31 do not comes with valve seals.. Nice video mate... Hope you soon figured out ur issue..

Loved your rebuild video. I just wish you had not used fast motion on the reassembly. Thanks for the GX31 breakdown and assembly.

Triangle mark on cam gear pointing down for top dead centre?

We've got the same problem.. It's an engine blowby.. There's a combustion leak somewhere in the piston and liner or in a valve stem. Crack in a liner and piston will show up when it is heated and pressured.

OK I will throw in my two cents. You said you honed the cylinder. After honing did you pull the compression rings into the cylinder and check end gap? If the gap is too large either the rings are wrong or you over honed the cylinder. Also what grit did you use for the cylinder honing? If the grit is too large the engine will smoke and have blow by until the rings wear the cylinder smoother. Rings. Even if they have the proper end gap they must be installed correctly or they will pass oil from the cylinder walls up into the combustion chamber. Since you are indicating oil being blown into the crankcase breather it is most likely a piston ring bypass issue. These engines are designed to run in all positions so it is possible you are sucking oil past the intake valve guide into the combustion chamber causing the blue smoke. If the head has removable valve guides that might address that issue. Most likely Honda doesn't replace them just offers replacement heads. My next statement is going to sound a little silly, but are you sure you are using standard gas not oil/gas mixture? Sorry for asking as you seem more than competent as a mechanic.

Look forward to part 2 on this. I have a Husqvarna 224L with basically has a Honda GX25 in it. Thanks for sharing Best Wishes & Blessings. Keith Noneya

very good job man !!

Excellent video!! It did look like you used the same valve clearance for intake and outtake. What clearances did you use if not the recommended .012 intake, .015 outtake?

Great video! Would a 4 inch diameter puller be large enough to remove the flywheel?

Been having a problem with low compression, and am sure to try check the valves now. Thanks. Had not thought of that... Btw, what's that gel you applied before grinding the pistons? And is there an alternative?

Yo repare 1 de las mismas y prendió todo bien pero el único problema esq no me sube aceite para los balancines no se qué hacer eh revisado y todo bien

He is professional

Oil coming from the crankcase breather is a sign of blowby at the piston. Thus either your rings do not seal properly, or your rings do not seal properly. Thats from a worn bore, or shitty/worn rings usually. Shitty rings can be either assembled in the wrong way (e.g. top down) or the ring gap is too large, or the preload of the rings is too low. If it does not burn lots of oil (blue smoke) it is a problem of the compression rings only.

Great video really helped me , but what sealer did you used for the gasket, the red stuff? thanks

Great work sir.

I had problem with honda umk 435 t when acelarat raises there is a sound in engine

habe auch eine umk 431 motorsense. bei vollgas geht der motor aus. Zündspule defekt?

The horrible clattering sound is your first warning sign that something isn't right.

I think it s better dont brush with rotate still brush the crankase brather. Good job !

fantastic job

Thanks sar

TDC before setting the valve clearance?

Hello thanks for the video, I had the following question; how did you position the piston with crankshaft relative to the gear that drives the valves. best regards

Medida en mm la luz de valvulas?

Hi sir valve gap and coil gap clearance?

Its good tutorial.

Thank you very much of repair tips! Can you please show too throttle control (handle) parts constitution?

hello sir. i have problem with machine won't start . i dont know what is the main problem at all . any suggestions... please share !

did you adjust both valves without moving the flywheel the second time

👍

Hi, have you considered the oil outlet valve in the bottom of the crankcase. It’s meant to stop oil draining into carburettor but still relieve crankcase pressure.

good

Hello thanks for the video, So am currently fixing a parazzini engine, and its smoking really bad, Also at one point oil came out of the exhaust. What could it be.

Why dont you show the filler gauge clearance

Sounds like garbage after rebuild. Why?

First, get the measurement of the compression that you're getting. For the low compression, it is either the rings or the valves that are not sealed properly. For the rings, you have to assemble it correctly. Make sure the rings are facing the correct position to get good compression. For the valves, have you do a leak test. The valves need to be sealed tight as well. Please get the genuine rings from Honda.

Hi. I'm using the same trimmer, I noticed the airfilter is full engine oil and spitting engine oil from muffler. And it's hard to start. Can you me help pls.

Hi. Please advise what is better to get, Honda UMK 435 or Makita EM4351UH?

5:00 what tool did you use to remove that part?

Thank you. Where are you from?

Me quiero comprar una honda 450 es buena ??? Se compara con la Stihl 450 ??? Digannn cual compro ????

How do you lubricate the honda brushcutter head

Can you help me with the name of two pins which you took out at 11:00-11:04min of the video.

Bravo

👍👍👍👍👍

Qual seria a folga de válvulas ideal

Hello, Size of oilseal for 4stroke

do I understand correctly-- oil pushed to carb because of leaking valves? anyway, love you work.

oil push to carb becaus of bad piston ring replace piston ring

O singură greșeală ! Siliconul nu se curăță la peria abrazivă, deoarece se strica fata de etanșare a piesei, salvarea este siliconul dar nu este corect.

can you make a video about the carburetor please?

Hi my friend where I can buy a genuine GX25cc and Gx35 Honda's

Kiya reason h

वायर खींचने वालाकैसे लगाएं

should of cleaned all the carbon shit off the valve before even attempting to use the valve grinding paste. can then see is the valve stem has any deformaties..... and actually would put new valves in anyway.. and only use those valves for grinding in process.

You need to talk to tell me what you’re doing
