The IPL (exploded parts list) for your saw can be found here:
Page 8 is the fuel system detail. Compared to most manufacturers’ this is a novel, a good one. Use it as a guide, it doesn't look to difficult. Take extensive notes and digital photo or two may pay huge dividends. HTH

Hello there,my 2001 echo is lighting up trouble codes p0440 p0441 p0446; how and where should i start?

code p0440 refers to evaporative emission (EVAP) system--malfunction=== causes --hose connections --intake leak--EVAP canister purge valve
code po441 refers to EVAP --incorrect flow detected==causes the same as for po440
code po446 refers to EVAP system vent control --circuit malfunction===causes --wiring---EVAP can purge valve--ECM
generally I would replace the purge valve as it is common to all codes

P0440 Evaporative Emission Control System Malfunction P0441 Evaporative Emission Control System Incorrect Purge Flow P0446 Evaporative Emission Control System Vent Control Circuit Malfunction
  • Remove and reinstall the gas cap, clear the code, and drive for a day and see if the codes come back.
  • Inspect the EVAP system for cuts/holes in tubes/hoses
  • Inspect for damaged or disconnected hoses around the Evap purge solenoid
  • Check and/or replace the sensor
  • Check and/or replace the purge valve
  • Have a professional use a smoke machine to detect leaks

While filling up our 2000 Toyota Echo at the gas station the pump at the gas island keeps shutting off. Takes forever to fill the tank.

this is becoming a common problem, what is going on with your car is that as you fill the fuel tank you have to displace the air inside the tank( as the fuel goes in the air has to come out ) this is done by the purge system, as the fuel goes in the air is displaced threw a purge canaster the canster trapes any fuel vapers that are in the displaced air and as you are driving the car the vapors are burned by the engine, this canister is either pluged or the valve that opens and closes the canister is stuck so as you fill the tank the air can not get out so you get back pressure in the fill neck and this causes the pump to shut off, bottom line you need to have the purge system checked. it might be a bad canister or a bad switch could also be one of the hoses to the canaster, heres the bad news to replace almost anything on the system the fuel tank will have to be removed and that can be expenceve....sorry

What is the spark plug gap setting for small ECHO CS3450 chain saw with new autolite plug?

0.020" should work well. Check the quality of the spark--it should be blue and snappy with the new plug. Hope this helps!
