"Hi, was out cruising the othe

"Hi, was out cruising the other day when the motor lost full power, dropping back to about 1/5 (around 2000 RPMs). The motor appeared to be starved of fuel, as it ran normally when the choke was depressed. I tried squeezing the fuel bulb, but this made no difference and was already solid. The breather outlet appeared clean (not blocked) and had actually been dripping fuel slightly the previous day due to the warm weather and expansion. There was still around 50lts of fuel in the tank, so this was also not the cause. The following few days have shown no sign of this power-loss problem. Does anyone have any ideas what I could look for? All 4 spark plugs were a little grubby, although they'd only done around 15-20hrs since being replaced. Cheers"
