Jonsered 920's and HS-219B & C RPM Limited Carbs....
« on: August 11, 2014, 08:21:18 am »
I posted this over at forestryforum....

Brought out my slightly "tweaked"Jonsered 920 and Spike60 his 930 & 820. Pretty certain my 920 has a limited Carb.. Couldn't get past 12,000. I want to know for certain.. Is there a way to tell from model number?? Don't want to tear it out and look as the thing is running well....It's either the Carb or Ignition! I think its the carb ..

Maybe this is a "sawtroll" question. Were the big jonsered's built with those rpm limited carbs? Or did I just end up with one because it was a junk pile saw...entirely possible!
 (Those Jonsered's were Supposed to have  HS-219B carbs....I think)

And the following is from the Tillotson Website... SO I guess this is the answer and I wasn't crazy.......NOW the question is the best way to beat the governor. (A New York State problem too.. :)   I wonder if there are different "springs" available to have different RPM settings

Look at the side of the carb  limiter is the larger brass slotted plug (screws in).     To defeat, pull the plug and check valve out and use a small piece of aluminum sheet or a Welch plug of the proper Size. Put plug back in a manner where the brass plug holds the aluminum against the orifice , sealing it

It is a bit odd if the HS-219B has a Governor, as the part list for the 219C doesn't list those parts?

Is that part list faultey, or is that differense actually there?
