2 stroke engines

RPWC · 2nd June 2018, 17:24

Anyone an expert in the field?

I have a 2t hedge cutter, it has been fine for ages, but today it kept cutting out and was difficult to restart. Did this a couple of times, then a third time it wouldn't restart at all, took plug out and cleaned it, cleaned fuel lines, still wouldn't start, so I took the top off, and checked all electrical connections,coiuldn't find fault, re assembled, and tried to start it, eventually it did after a few tugs, then I switched it off, pulled the cord, and it started first time, finished off the hedge, and put it away.Can't be a case of overheating cut out, as the machine is air cooled, anyone got any clues?

I'd try pulling the carb to bits, cleaning jets etc before going down the replace route.

Usually plugs with 2 strokes, especially if they have been stood, the oil tends to separate out then foul the plug. Easy to flood them too so then need a delay before they'll start, which is what that final check gave.

There is a bloke nearby who services and repairs garden machinery, so will get him to look at it. Im not confident in pulling it apart myself. Made tbis mistake in the past, thought I could do something myself, then had to pass on to someone to finish it off.

could be modern fuel. has it been stood over winter, apparently, modern non premium fules contain less preservatives than they used to and basic petrols contain 5% ethanol.
