    Echo 2511P (rear handle) in the states. 7310p as well

    There is a member here and he has vids on youtube of him running the new 7310P, and porting it. I think he actually made his own full wrap handlebar. He does know what he is talking about so I would say based on that there isn't a wrap available....Yet. The CS620 has a wrap available and if i...

    Spark plugs at the Stihl dealer

    Just a little FYI at least as it pertains to automotive spark plugs (generally the $$$ ones like iridium/yttrium ones) there are counterfit NGK plugs on the market, usually found on ebay and amazon. I had a friend that had this happen to him for some plugs he bought on amazon, IIRC he called NGK...

    Spark plugs at the Stihl dealer

    NGK has always produced good results for me. The few plugs that I had that were no good were other brands, usually champion. Not a big enough sample size but just my experience.

    How much pressure builds up in the gas tank?

    How much pressure (PSI) actually builds up in the gas tank during extreme heat, sunlight/high ambient/running hard ext? I'm wondering about the rule of thumb I heard of not going lower than 10 PSI on the pop off pressure and if thats due to pressure build up in the tank as a saftey issue or...

    STIHL Progressive Depth Gauge Tool

    Does anyone know of a canadian supplier that has these and will ship to the USA? Might be the (my) best bet. I found a couple suppliers in canada but there is no option to select USA in the shopping cart. Also is stihl and husky the only game in town for gauges like these? I haven't seen any...

    2 cycle oil choices

    Note that the JASO FD Note also that the allowable ash content is not the same from FC and FD, FC and FB both spec sulfated ash mass % of .25 as a max allowable, while the FD specs a .18 limit. In the real world what difference does that make? I have no idea. Check out this link to the JASO...

    Husqvarna depth gauge, Whats the difference?

    Quick question, I just ordered a husqvarna depth gauge from a vender and it does not have "EM" stamped on the front of it (505698101) while the picture on husqvarna's site is stamped EM (596285102) It seems I ordered the older part number. What does EM mean? And what if any difference is there...

    Make sure it passes jaso FD and iso EGD and then from there find the cheapest one. Then you know you are getting quality at a lower price. Now there are companies that CLAIM to pass these tests, and others that pay the $ and actually get certified.. Lucas claims on i think its 2 of their oils...

    Dolmar Makita 7901aftermarket replacement carb

    Futher update, the hole on the choke arm on the chinese knockoff husqvarna carb, is much larger than the original zama. However the choke lever does work fine with this larger hole. The only time the lever might come unhooked from the arm would be when pulled out to full choke. It makes the...
