Timing Check

[Simonizer]

Sorry to hear your story Simon.. Take a deep breath and relax you'll be ok...
Does that pawn shop give good deals on tools..

I don't know, I just threw them under the arm of my flea-bitten parka and ran just as fast as my little legs could carry me. When I was safe, I walked back to the dumpster, (home), jumped in, and started porting a cylinder with a nail-file I found in a bag of garbage.

 

[Mr.]

Just tell if it's within your previosly posted specs.

You can call me for porting configuration if you need too, but my timing is top secret.

WOW Simon thats how you got your start.. Tell us more

 

[Mr.]

A new age of misinformation has dawned upon us. The internet.

Please do not claim to be an expert and not hold up your end of the bargain.

That is not how I got my start, that is the position I have worked myself up to at present. I collect the odd pop can to help out financially sometimes.

I would give porting information, (just not mine).

 

[Mr.]

I would give porting information, (just not mine).

You wouldn't give them to me.

I wouldn't listen.

You have to resort to childish games to skirt an arguement.

Fred

Fred

Are we arguing Fred? Do you have a 372XP?

 

[Mr.]

Get within 3 degrees of stock 372 timing and I will take back my assertions.

Fred

 

[Mr.]

Are we arguing Fred? Do you have a 372XP?

I am not argueing merely asserting you did not have a frame of reference for previous info.

I have several.

Fred.

365s, 372s, 375s

 

[Simonizer]

Get within 3 degrees of stock 372 timing and I will take back my assertions.

Fred

On the 537 1622-04?

 

[Mr.]

My apologizes at my office bringing chainsaws is not an option. I assume you are referencing the 372 with the new rev limiting coil.

Fred

Fred

No, the coil with the non-integral frequency-counter based rev-limiter. The black one. 22 degrees BTDC.

 

[Mr.]

I have to leave for a meeting, but would like to point out it has been 50 min since Simon first responded. I hate to miss out on this. How about tonight?

Fred

 

[ShoerFast]

He asked how to check the timing, peckerhead. I gave him an answer.

This should sum up what slimon knows about setting Ing. Timing,,,, as it was taken from the post in a tread about why his Ohio 385 was really not that spacial,,,,

Ign. timing remains the same, although it is an earlier model coil without the rev limiter. "A little clean-up on the ports,.." ha ha.

What production stock dose to tune figures is to set things way lower then what is best as a means of establishing a safe standard deviation. IOW, it is intintionly de-tuned.

Add that the EPA is setting guidelines since 1997 to comply with NOX emissions, the timing is one of the first items hit, by 2007 stage II will take effect, saws like the 372 will no longer make the grade so to speak, as they simply wont meet the NOX standard, by 2012, all small hand-held engines will be in compliance if there to be sold in the US.

Stage III has not been announced yet, but if the trend persist, my guess we will start to see micro-prossers tailoring the fuel and timing? intill then, we will see gains by resetting ing from up from stock, just as we always have.

Simon your out of here.. For stalling..

 

[Mr.]

Got 5 seconds. That doesn't corespond with my findings though. I haven't tested that specific coil though. I will check one tonight.

fitting in

Yup, grade 3 education, tools I bought from a pawn shop, scraping by on minimum wage,...things are tough. Do I fit in now? Do you think I will be popular on AS? You know, this is my only real concern in life.

The hardest thing to overcome in life is the fact that you are an engineer. While there are more than 30 engineers listed as AS members, engineers have a hard time relating to folks that aren't engineers unless they had to take a lot of mind numbing classes in the art of socializing while in school learning to be an engineer.
Most tree fallers know the physics of falling a tree but if you ask them if they use physics they think you're asking if they drink enough beer to give them the runs. They'll say, No! (even when they do) They don't want you thinking their production tomorrow will be inturpted be trips to find a bush (hopefully, one with large leaves or a handful of soft pine needles nearby) to hide behind for relieve.
Now it's their saws that have to have more poop in the woods and any talk of using physics to achieve this has them going for your throat. A little less talk about theory and a bit more show me the saws is best.

That is why we have a 4 foot diameter log outside the shop. Anyone can run any saw they want with any bar and chain.

That what I use, unless I going a running test, then I use the Stihl ZAT4.

The sparkplug/wire works the best.. but I grind off the grounding electrode and use a plug with the ceramic not protruding. Much easier to evaluate the spark as you are forcing it to generate a higher voltage to bridge the gap. You could just bend up the ground electrode vertical. Why? Ability to spark is dependent (amongst other things) on voltage and pressure... It take a lot less voltage at 1 atmosphere of pressure than 10 (which is why magnetos are pressurized on aircraft above about 15,000 feet, but that another story...) so, forcing a higher voltage at bench test is more realistic evaluation of ability to spark inside a combustion chamber.

check out the ignition trak tool, gap is pressurized during testing
