arpie Posted November 6, 2013 Share Posted November 6, 2013 Hi guys Damn!! Keith put 4 stroke oil into our 2 stroke motor mower (about similar or slightly more than if 2 stroke oil quantity per 5l) and the mower stopped. Keith said the spark plug was 'clogged up' with oil!! (Apparently the 4 stroke oil floats rather than 'mixing' with the fuel as '2 stroke oil' does ......) We have drained the remainder of crook fuel out ..... and purchased new oil & fuel ...... the compression still seems to be OK (I pulled the crank and at least it still turns over ....) so hopefully no piston damage ...... Is there anything else we need to do before we put the 'new fuel & correct oil mix in' to try & minimise the damage that may have already occurred! Sadly, we only bought the mower recently - altho not 'new' - it was 'as new'!! cheers Roberta Link to comment Share on other sites More sharing options...

Testlab Posted November 6, 2013 Share Posted November 6, 2013 Pull the carby apart and clean it out. It's going to gunged up with oil in the bowl and jets. After that it should be ok providing it didn't run too long on what was (to it) straight petrol. Link to comment Share on other sites More sharing options...

arpie Posted November 7, 2013 Author Share Posted November 7, 2013 (edited) ......Keith = Fuel Preparer ..... Here I was, thinking it was a major 'part of the engine' that I'd never heard of!! he, he, I cheated & took it to the local mower expert ...... for $5 he put fuel in the carby & cleaned the plug & put new fuel in & BINGO! She is back to working normally again! Thanks for your help cheerioRoberta Edited November 7, 2013 by Roberta Link to comment Share on other sites More sharing options...
