No not gold or salt, platinum. I've been running the silly things for 35 years cutting firewood and such, even used my best profanity on them but that is the best how-to-tune information I have ever gotten. Thank You.
 
Great Job on nailing the 4 stroking sound

Great job.
Took some of the mystery out of the process. I am a newbie but am now willing to try to make the adjustments.

Ht75 Tuning

I watched the video (thanks much!) and tried it today on my HT75 polesaw. I'm not sure if I ever got it quite right. I finally decided if its rich enough that it doesn't bog when I hit the throttle and it seems to be four stroking a bit, just to leave it alone for now. Does the Zama carburetor have fine enough adjustments to really hone it in, or is it more of a get-it-into-the-general-vicinity proposition?

I'm no expert like Brad and some of the others on here, but the answer is yes - the Zama has just as much fine adjustment as a Walbro or Tillotson or anyone else's carburetor. When you're going to tune a two stroke, be sure the air filter is clean, the muffler screen is not clogged and that you have at least 1/2 tank of good, fresh fuel. There are a few other things that can give you a "false tune", but those are the most important ones. When in doubt, tune it a little rich.

And, as others have already said, Brad takes his share of grief from others for a variety of reasons. As far as I'm concerned the ones who complain about him have issues of their own they need to deal with before bashing him. Brad puts out some great videos and tips filled with solid, easy to understand information. I have benefited many times from his past experiences and hope he stays around for a long while.

Stay safe...

Outstanding information to tune my saws. Love the video clips. My hearing is not that good but with headphones I can pick up more of the noted sounds that can make a difference between a good tuning and an average tuning. THanks so much. Looking forward to seeing more and also finding more as I search all the threads. I'm starting to think I will be keeping my eyes out for more used chainsaws at garage sales from now on. With the information that everyone is providing it could become addicting. I like to tinker. Arrow13
 
I am pretty new to tuning chainsaws. My question is why wouldn't you read plugs and piston wash also to assist in tuning. Sound can be interpreted in different ways by different people.
 
I just found this old thread and wanted to
add my thanks for help me to better understand 4-stroking.

:rock:
 
i know I'll feel like an idiot...

what does WOT stand for (crouching with hands protecting head)...
 
i knew id regret it

i had a feeling it was something i should have been able to figure out.

Every now and then you'll see someone say WFO instead of WOT. Coming from the automotive field, I was not accustomed to slang acronyms. It took me a while to realize the F in WFO was indeed the F-word! WFO=WOT

This is a great thread :clap: Good work!
 
not trying to hijack or anything but here is the one i did not to long ago
