    Does Anyone Have Any Other Hobbies Other Than Falling Timber and Working on Saws?

    Turning wood, all forms of bowls - both "normal" and offcenter. All fashion of spindle turning, especially boxes. Enjoy making fixtures and tolling for my woodturning. These days, the woodturning is more of a job than a hobby after my job got sent to Russia. When I get off here, I have two dozen...

    Four stroke chainsaws on the way ?

    That Saito .72 will only turn about 11,000-11,500 in the air due to valve float. A similar size Super Tigre, OS, or Rossi 2 cycle will turn around 16,000 in the air. I have over half a dozen of the hybrid R/C 4 strokes similar to that one. You still mix the oil in with the fuel (methanol and...

    alcohol 2 stroke

    For about the last 40 years or so, FAI model airplane competition has been a no nitro fuel event. Their fuel is methanol alcohol and oil (80%/20%). These are 2 cycle engines, so yes methanol and oil will work in your chainsaw.....but and there is always a but. Alky engines are a lot more...

    Mod New Saw for E10? Really? (was two 310's blown up in a month)

    Poge, No problem, I look at things a bit different than most. As I stated my new 361 had about 30 seconds run time with the factory settings and dealer fuel. Before I ever ran it, I changed the caps and settings -along with the fuel mix. From reading other people's problems and experiences...

    Two 310's have blown in a month

    Poge, I guess I should have said that those numbers apply to any engine (2 cycle or 4 cycle), but the thread was about the 310 and I was thinking about the 290/310/390 series. I got a bit po'ed when my saw died and started doing some reading about the EPA "stuff" and found that info. My...

    Two 310's have blown in a month

    Pogo, The fuel/air ratio numbers came from the EPA website under reformulated gasoline. These are the numbers that Stihl, Husky and all the other manufacturers have to shoot for - and the reason for the limiting tabs. Fuel air ratios have always been at a specific temp and altitude - 70...

    New MS362 Vs. New MS391

    Big difference is one has more metal and little plastic (362) and the other is more plastic and little metal (391). They are both strato engines, but the basic construction is still the same as the 361 and 290/310/390. One has a removable cylinder and the other is a clamshell engine. I have...

    How long before chuck fuel?

    After E10 killing one saw, I now mix a quart at a time. On my saws this is about two tank fulls. I start with a quart container full and mix more as I need it. I add StaBil to the gasoline when I buy it and keep it out of the sun and heat. I have clear graduated cylinders that I use for mixing...

    Two 310's have blown in a month

    Sounds like E10 gasoline. I have a 290 that had been running OK, not great but OK since 2003. E10 was pushed in our area earlier this year and there were a number of saws, including mine, that have the same problems as the ones you described. The condition of my saw was the same as you described...

    Why Klotz?

    KL-100 is what they are calling Super Techniplate and KL-200 is the Original Techniplate. KL-100 is KL-200 with 20% castor in it. After having run engines with castor and pure synthetic, I can see no reason to run anything but pure synthetic. I have heard the same "stuff" that you should run...

    Why Klotz?

    I have been using Klotz for over 20 years now and never had any problems with it. I don't use the KL-100 as I don't care for the problems caused by castor. With the synthetics there is no need for castor, that is a carry over from the 30's when that was all they had. KL-200 is all synthetic and...

    Stihl MS290 Rebuild Problems/Questions

    Thanks to all for all the information and sharing your experiences. Learning something new is always a good thing. Looks like I will be drilling the head off the bolt tomorrow - can't get the remaining fragments out of the bolt. I looked at Thall's video on removing the bar stud a couple of...

    Stihl MS290 Rebuild Problems/Questions

    I am in the process of rebuilding an MS290 to correct damage caused by ethanol. I have a new engine and have disassembled everything that I need to. All that is left are the four bolts that hold the engine together and to the plastic frame/chassis/crankcase (depending on where you look as to...

    Anyone getting a new or used saw this weekend?

    I picked up what may be the last Stihl 361 in the Houston area. This was after a friend called Firday evening who had picked up a "back up" 361 to go with his other 361 - and told me that there were no more in the Stihl warehouse, there was a run on them in the area. He had to drive out of...

    Carbon Analysis On Piston Crown

    After loosing a saw to the EPA and ethanol, I looked at Klotz R50. But, it won't work in the Houston area as all the gasoline has ethanol in it. I called Klotz about the alcohol compatibility and after talking to them decided it wasn't worth the risk. It is "iffy" - should mix with low amounts...

    MS290 Rebuild Questions

    Thanks to the EPA and a less than honest dealer, I now get to rebuild my MS290. But, I have a few questions about these engines. My background in 2 cycles is over 30 years of high performance racing engines. They operate at higher rpms - 28,000-29,000 compared to the 12,000-14,000 of my 290...
