Right now it s 3 weeks after the first meaning full rain in 8 months and the grass has shot away
There is a que of mowers from the workshop to the front fence , all needing a carb clean.
Done 47 in 3 weeks, got another 22 booked in.
Your carb is blocked or it is not getting fuel
Rig up a tank of some sort ( pinch one from your push mower if you have to, or a motorcycle whatever.
Hold it about 1' or more above the engine then plug it directly into the carb.
Problem goes away = crud build up in the carb
Problem stays = crud in the fuel lines.
