I recently bought a Ryobi RLT-30CES strimmer to use instead of my RBC-1000EX electric one where extension leads won't reach. They both use the same "quick change" attachment system and I'm pretty happy with them.
However I find the petrol one very difficult to *re-start* if I have stopped for a few minutes, for example to change attachments.
I can start it from cold with no problems, it sometimes takes a little while to warm up and run consistently but that's all. I don't think I've ever had a problem starting from cold.
Similarly if it's hot, i.e. I've just stopped it for a few seconds for some reason, then it just restarts with a pull of the cord. I usually find that it's easier to restart with the throttle left at tickover in this case.
.... but if it's warm, as opposed to hot, I'm finding it a real pig to restart. Is there some consistent technique on can use to avoid, on the one hand, flooding it, but on the other hand to be sure it's getting a rich enough mixture to start?
The cold start sequence is:-
Pump to fill the carburretor bowl. Four pulls with full choke. Switch to half choke. Pull and it should start (needs some throttle) Wait to warm up Switch to no choke
The hot start sequence (according to the manual) is:- Check there's fuel in the carburretor bowl. Pull and it should start
So, what do I do next if it *doesn't* start when hot? Go to half choke and try again, do the whole cold start sequence (except pumping to fill the bowl), or what? What often seems to happen is that I get worn out trying to restart it, I remove the plug and give it a few pulls to ensure it's not flooded and then a cold start sequence works because it is just about cold.
