Question: String Trimmer
My 15 year old unknowingly filled my string trimmer with regular gas. What must I do to reverse the problem of the thing not running?
Reply: String Trimmer
Unfortunately once a 2 cycle engine seizes up the only way to repair it is to replace the SB1065 short block. If yours did not seize up you will have to tear it down completely, check the cylinder walls and piston for any scoring. If any scoring can be seen the short block will still have to be replaced. If it all looks okay make sure you lube the internal parts. Then make sure you get all of the gas out of the carburetor. It would be a good idea to put in a P005000950 repair kit in while you have your carburetor off.
Good luck & I hope this helps,
Question: H Needle Setting
These things are set "lean" per EPA regs. If you access the H needle, and clean it to remove it; what is the optimal setting for it? Too many turns out, I have encountered flooding and too far turned in, extremely lean and carb dies running.
Reply: H Needle Setting
This looks to be a really nice forum. Professional and neat...BUT...it is dead, nobody responds to any questions...weird.
about your question on the needle screw adjust...your calling it "H" as opposed to "L" right ?? that stands for 'H'igh or 'L'ow rpm's.adjustment of air flow. the near correct setting is about one and one half turns ...1 1/2...out from snug clockwise..dont over tighten , you could bend the tip.
While the motor is running at a slightly high idle turn the H screw inward clockwise slowly and listen for an increase in rpm's ,,faster,, keep going clockwise till this sound begins to drops back off,, then turn the screw back counter wise till you get that high pitch again.. that should be good for the high idle... Do the same with L screw for low idle while motor is running slow or idleing... hope this helps someone...and hope I am addressing the correct subject( screw in question)..
I have to say that I just noticed that this post is not as old as I thought ,,the date I saw in June is actually the join date of your account...lol
Question: Roller Guide
I can not find a diagram that shows where to place the Guide Roller for my SRM-210. Can you help me with this?
Reply: Roller Guide
I have the same question can someone help?
Reply: Roller Guide
I think the roller guide is placed inside the throttle bire (with plastic throttle linkage and rotor and spring removed) on the end of the steel pin that is extruding horizontally into the bore, It is VERY small and very easy to lose, and it is made of chromed steel.
Question: Carberator Flooding
Good little machine but the carburetor keeps flooding when I accelerate to edge. Any adjustments I can make?
Reply: Carberator Flooding
I've had my SRM-210 for years. Never had problems until I had to hire someone to work my yard for a year. He had the carb over adjusted - the head would spin without depressing the gas. What I did was back out the screw just until the head quit spinning. Now if I could fix the other problems....
