  1. FullSizeRender.MOV IMG_0244.MOV Hi folks a while ago my CS100 was getting bogged down and cutting out, so changed the filter below the tank as fuel wasn’t free flowing. At it again but its hunting now at higher throttle. Im sure i heard that these sometimes do that but most guidance says the governor should hold it steady even under load. Any thoughts I’m thinking this is just a carb strip clean out jets to sort this? Any pointers gratefully appreciated. cheers God Save the King!
  2. I've been checking the revs on my little Echo saw, I followed the carb adjustment procedure for bringing the saw up to temp which involves a couple of minutes of switching from idle to full throttle to idle etc. Then checked the max revs which were about 12,000, so under the max revs listed in the user guide of 12,500. So far so good. However, I decided to check them again after using the saw for a bit of logging and noted the max revs were over 12,500 although only by 100rpm. I assume this is to be expected, i.e. after a fair bit of use the revs may well be higher than when a saw is tuned at service? Also would a saw be able to cope better with revving slightly over maximum revs if a good quality 2-stroke oil is used?
  3. Hi, everyone. I retired last year and know nothing about petrol engines/chainsaws/mowers but I am interested in expanding my knowledge, that shouldn't be too hard to be honest! I've already bought and fixed two non-running petrol mowers for a few quid and can't begin to tell you how much of a kick I got out of it. This week I bought a Partner 370 Chainsaw on the Bay of E listed as a non-running 'spares or repair' chainsaw. When I picked it up and got it home I saw that the Primer Bulb had disintegrated so I knew I'd have to replace that. I took all the covers off to access it and noticed only one fuel line was attached to the Primer and that went straight into the tank. Maybe I would find the other missing fuel line inside the well somewhere - which I did once I'd detached the carb and could get a 360 degree view all around it. The only thing is, I can't find a nipple on the Walbro WT239 Carb as there appears to be only one and that goes straight into the tank. Any knowledgeable folk got any ideas? I've trawled YouTube and gawped at the carb till I'm blue in the face. There is a Poulan Chainsaw which looks to be exactly the same in the States but I still can't get the info I need. Much appreciated in advance.
