Stihl HT101 running issues

[PhillH]

Red Stihl oil isn’t recommended for 4-mix engines as it carbons them up. We used to have issues but moved to the green oil and have been fine since. 

Cheers Monkeybusiness, I had read a few post about them carbon’ing up. Definitely worth a try to see if we notice a difference

Thanks for your help

My 101 had the same issues, although I run it in Aspen. Went in to Stihl shop and they “ put new valves in”. Runs just like a gypsy stick should now [emoji106]

Try the easy options first and then explore the more difficult ones if the easy ones don't cure it. It always helps to know the age and condition of the unit.

@oldwoodcutter thank you for sharing, I hope it does not come to that. Let’s see how the carb overhaul and new mix goes first.

Thanks again.

@spudulike it’s a 2015 but in very good condition and had very little use. That’s the annoying part. I will go with your recommendations and let you know the outcome.

I’m certainly no oil guru but have heard from someone with a lot more knowledge than me that the Rock Oil Groundsman oil is apparently very good/high spec, better than the stihl gear.

The "very little use" means more than the year. With a machine like this, I would always look at the carb and fuel filter/line after adjusting those niggly tappets of course....and then look at other possible issues!

Thank you @spuduline your the man who knows I hope your right. When I took the cover off to check the tappets, it was very clean and shiny so I do believe my dad when he says it has not done much. Are these ZAMA C1Q carbs adjustable as I read a thread that say they are not. They have the 4mm heads

Ah...Zama C1Q.....the C1Q is fitted to a raft of machines....blowers, saws, strimmers and all are slightly different. The adjusters on yours I believe will be "Hexagonal" ones, you just need the correct adjustment tool, you may find it just needs a bit more fuel and an adjustment will sort it - seen it many times before.

Same as one of the sets I have and does pretty much all machines that I have come across...apart from Autotune

Stihl like to set their settings a little lean to adhere to the EPA regs - it means some machines over rev when they loosen up a bit.

Hi@monkeybusiness thank you, that’s is good to know.
