hello craig,i really appreciate the comment you upload and love how much you go in detail with your explanations,nobody else in this platform shares that much info about small sized engines as you do. i noticed that in your older videos you used to have a website where you said there where leaflets with step by step guides on how to fix a variety of problems,unfortunately the website is now gone so i was wondering if you could somehow share those leaflets with us again,i don't believe am the only one who is intrested in this,thank you in advance and keep up the good work😁
On my chainsaw, I can pull the choke to get the high idle and get it to cold start. Then I feather the choke valve as the engine warms up. After a minute or more, I can use the throttle and the choke will come off the high idle. once it's fully warmed up, the chainsaw will usually idle when I set it down to get another piece of firewood ready to cut. Sometimes the saw will stall out and it doesn't want to start unless I set it at high idle with partial choke to avoid flooding the engine. I found the low and high mixture screws function similarly to the primary and secondary fuel system on a 4 barrel carburetor. The smaller 2 strokes are really simple to fine tune once you get the hang of it. For a while, I was running the mixture a bit on the richer side and it wasn't getting very much power during the cuts. One of the times I ran the saw out of fuel, it suddenly revved up to full power just as it ran out of fuel. Then I readjusted the fuel mixture slightly leaner while I had the chainsaw jammed into a log and I made the final adjustments to make it scream. I found that bench tuning it would cause the chainsaw to lose power while cutting through a thicker log. 42cc 18inch bar Poulan Blackhawk that I bought as a lemon on Marketplace over a year ago. I had modified the muffler and upgraded to better quality fuel lines. The seller said that it needed a carburetor kit. I never touched the carburetor other than making the necessary adjustments to the fuel mixture and the idle screws. The saw is a bit louder with the little bit of modification to the muffler. I haven't made any porting modifications yet. The saw was previously used in doing demolition and renovation jobs by the previous owner who had purchased the chainsaw when it was new. He would cold start the saw and run it wide open throttle on a cold engine indoors and it caused some scoring to the cylinder wall and it may have lost a bit of compression. I didn't bother to do a compression test. At some point in time before I bought the chainsaw from marketplace, he had taken the carburetor off and tried to clean it or something. But the dummy with his sausage fingers put the fuel lines back on in reverse order and also caused a binding problem between the choke lever and the throttle cable. Luckily I was able to figure it out and got it back together correctly. Real mechanics are becoming more and more rare in existence where I live. The majority of repair shops and parts counters always recommend to discard the non running saws and purchase a new one. I don't have that kind of money to keep good equipment going into landfills and scrap yards. I'm one of a fortunate few who likes running old junk. The poulans are one of those throwaway brands that even most sellers are scared to talk to me when I'm looking to buy another non running chainsaw. I've never complained about the poor condition. It's just these guys probably feel bad for selling their junk at such a high price. As long as I can get my money's worth out of it. I got nothing to complain about
I’ve got a question, I have a 2 stroke blower. All works well . But when you put it on the ground and go to pick it up it stalls/dies . Cranks seals checked no leaks , 150psi compression . Changed carb still happens , new fuel filter , spark plug ,air filter . Any ideas ?
Thanks for the clarity Craig , pictures are worth alot 😄
I really appreciate it. Craig 👍👍👍
Great video to share with people I repair there machines. Thanks
Thank you so much 👍👍
you make the best videos craig!
