You have to be careful with the 4 stroke as there is two top dead center, you want the one when you move the fly wheel a bit the valves do not move. Go check Steve’s small engine saloon.

you right!

I am a stihl certified tech you are 100% correct on how to do that allso be careful when you put the new gasket on the cylinder there are little guides the gasket goes around and if it has over 15% blow by to clean the carbon out on a br430 there is a little mark on the flywheel

Nicely done with good footage of keys points. Pace was perfect!!! Thanks again!!

Good tutorial video. 👌 I really liked at the start your emphasis on throwing the old gasket away immediately. 💯.

I’ve got an older km110r and the last time I had the valve cover off it look extremely clean, I’ve always been very good about maintenance and it’s been a very dependable trimmer, it did seize a valve once but that was quick and easy to fix, I run 32:1 mix and I have no issues with carbon, I do run it wide open frequently.

@@THEMOWERMEDIC1 I did switch to syn oil a couple weeks ago, still 32:1 due to the fact that I run my machines wide open. Haven’t seized a valve ever since. I currently use hp ultra but will be switching to red armor soon

Thanks for the info , is it the same for a poulan blower ?

You forgot to mention that you want it on TDC on the compression stroke. TDC occurs twice on a four stroke in one complete cycle.

Under normal conditions (not making a vid), would you clean the rocker arms etc.? If so, what do you recommend for that?

OK, good info. I have that problem. What feeler? It will take weeks till I can get that order to me for the kit. For the mean time what feeler? You can tell me in metric or sae. I've got both.

Very useful info

Thanks 😊👍, I learned something new, this day, Iwas doing it wrong

The 100rx I use at work seems kinda low on power. Idle is constantly different some days slow some a bit faster can’t get it turned down low enough for the head to stop turning without it sounding like it wants to die. It is at least a 8yrs unit and did have a new carb out on in 2017 also tune up, and valves adjusted, but as I can recall it only ran really good and properly for maybe 2 or 3 months by the next year it was acting similar to how i mentioned in beginning.

I've had issues with the screws on the bottom engine pan backing out. make sure you check them everytime you adjust the valves. Has anyone else had this issue?

I have a Stihl fs 91 r weedeater and gas I leaking at the muffler and leaks a little at the filter how can I fix it

So do all the 4 mix's take the same valve adjustment kit?

Could you please tell me where the exhaust valve is located on a Stihl FS 45, or if it even has an exhaust valve and/or intake valve on this 2 stroke engine? It is terribly hard to pull the starter.

2 stroke engines don't normally have any valves.

I have A fs 135R. How often should these valves be checked? I wouldn't want to waste A gasket if they don't need adjusted.

​@@garypitzer8729 depending on how often you cut, I have to do mine at least twice a year. I cut 4 lawns.

By saying make sure to adjust top dead center on the compression stroke not the intake by that do you mean in other words if I wiggle the flywheel back and forth the valves shouldn’t move at all? Then it’s on compression stroke if they move up n down it on the intake? That’s how I adjust adjust but did have issue with it not running that much different afterwords so I think it was because of not changing out the 2 sealing gaskets. Either that or that didn’t need adjusting I don’t think they need to done that often and Stihl doesn’t make it clear what all contributes to valves being out of adjustment.

I agree with MM1 ............ Why did you change your head ???? Bad valves ???? What gap did you set at ??? I see you are in the lawn care biz and you got some wrench's under your belt I assume......... Comp releases or a common failure on Briggs cams on the single's .... I haven't seen one in my shop on a Kawi 6 HP though... Most Kawi's we have down here are on EX MARK and the higher end Zero Turn mowers........ Here in South Louisiana we have mostly Briggs on push style mowers...... Kohler Dis Courages LOL are getting frequent in the shop now with all kinds of issues with the bolts loosening up and cracked blocks.... What is your Model number on your engine ?? FC 150V ??
