Service & Maintenance Question
The operators manual under Technical Data specifies a Champion RCJ8Y spark plug. I replaced a Champion RCJ7Y Champion spark plug after takling to customer support to verify an 8Y was correct after observing what I believed to be the original was a 7Y. The blower, which previously NEVER operated poorly, clearly did not like the specified 8Y spark plug. It dies, it missed, it ran rough and I am concerned I may have damaged the motor by running the called for 8Y spark plug. Today I cleaned and reinstalled the old 7Y spark plug and the blower ran great. I believe the Tehcnical Data for this model blower is incorrect and want to talk to someone at Husqvarna who knows the subject matter. E-mail votestu@yahoo.com

Hi Stuart,
Thank you for contacting Husqvarna. The correct plug for that model is a RCJ6Y. Not a 7 or 8. This information can be found in your owners manual under technical data. If you don't have your manual you can find it here. /images/us/homeowner/home/ . But the number only designates the temperature range of the plug and shouldn't have such an immediate impact. Only if the plug you put in didn't have a resistor "R" style plug then I could see it running very rough, if at all. All our hand held products require the resistor style plug to operate properly. Hope this helps.

Now I am really confused but a tad enlightened. Apparently the "R" got past me when I replaced the plug. However, I double checked my hard copy owners manual technical data and went on-line to the suggested site and checked that owners manual technical data. Both list the RCJ8Y spark plug. So how did you come up with the FCJ6Y plug?
Spark plug Champion Champion Champion
RCJ--8Y RCJ--8Y RCJ--8Y
Electrode gap, inch/mm 0.024/0.6 0.024/0.6 0.024/0.6

I have a Husqvarna 125B blower I have owned since new for maybe 3 years now. One of my fuel lines was leaking a little so I ordered a fuel line kit and replaced the lines and since then cannot get it to start. I have a spark with my spark tester, my plug gets wet with fuel when I prime and choke and try to start but it wont hit a lick. Muffler is not clogged and I have tried putting a small squirt of gas in cylinder and putting plug back and it wont even sputter. I have tried starting fluid in carburetor and it wont even hit. I am at a loss.
I am a really good tinkerer with power equipment, replaced seals and reed on my Lawn Boy Duraforce, rebuilt plenty of carbs but this is a real bear. I have pulled kill switch to rule it out and it wont try to hit with kill switch out of equation.
I am wondering if the coil is weak and not giving a good enough spark to fire under compression?? I rebuilt the carb after all this started and I have reset high and low to 1.5 turns out and get fuel to the plug but still nothing.
Any suggestions out there before I buy a new coil and maybe a new carburetor after that? Or even better to buy another leafblower like http://jonsguide.org/best-4-cycle-weed-eater/ Hate to throw in the towel but by the time I buy those I am a third of the way or more to a new one.
