MAKITA MM4 EB7660TH VALVE CLEARANCE ADJUSTMENT / TOO MUCH COMPRESSION?

[@benjaminleslie3155]

This is very informative, now I feel somewhat confident to tackle this when the day comes.

[@moc6897]

Well done, Sir! No more panic on the Titanic!

[@duaneolson3998]

Where do you set the piston to adjust valve. I missed something somewhere. Great video though.

Amazing what a couple of Thousanths of an inch will do for a small engine! Good work Jeremy!

[@henrymurawskibigdogrepair]

Job well done Jamie

[@nashguy207]

Great Tutorial and video!! Keep up the great videos!!

[@jensenwilliam5434]

Thank you!

I use a Stihl BR 700 at work that gets really difficult to turn over when starting but otherwise seems to run fine, would this solve that problem? And would the measurement for the valve lash be the same?

Cam worn out

After doing the valves on my snowblower, I got myself a set of t-handle Allen wrenches. The handles give you a better grip and more room to tighten the nuts after. I have to check the valve lash every year on this machine, couple years back I broke the connecting rods during the worst storm of the year. That's how loose the valves got 😐

What kind of reading are you supposed to get when checking the compression on these engines? I have a mm4 concrete saw and the compression is under 30psi.. but the cylinder has a beautiful crosshatch pattern..

It will breathe a little better now.

My valves are extremely dry. Is that normal? I use 10W-30 oil as recommended. Additionally, my blower operates fine without the muffler, but when I reconnect the muffler, it loses power, and I also notice some mist coming out from the carburetor

Jeremy, what is the gap for a EH025 Makita blower? In/Ex?

[@ncrdisabled]

is that a ohv machine ?

[@moc6897]

Yes, it is, an "over head valve" ...

[@hphillips7425]

Was that a normal amount of required adjustment for the time on the engine?

[@THEMOWERMEDIC1]

Greatly depends on how well it’s maintenanced

[@archielb5967]

Hi I have the eb5300th and one off the rocker arm had snapped and can’t find them for sale anywhere. Was wondering if the ones for the eb7660th would work on mine.

[@usanzac]

Hi likelihood. This video shows something that looks exactly like my eb7660th

[@shirazmawji]

Hi, What about the top dead centre. How do you find that before you adjust the valves? Thanks

[@usanzac]

Look through the spark plug hole, rotate the crank until you see the piston at the top of its compression stroke. If you there is no play, rotate the crank again until the piston comes to the top again.

[@robertyearian227]

What about setting on tdc is it needed

[@THEMOWERMEDIC1]

Yup

[@jaimepadilla9548]

Does is the gap different for every application
