Hi guys

I have got a Ryobi RGBV3100. 2001 model Ryan engine, with the easy switch knob to go from vac to blow. Had it a couple of years but never used it. I scored a bag for it cheap the other week. The fuel lines were weeping so replaced them.
Has always been a pain to cold start in that it needs ¾ choke for a good 20 seconds to keep going. Runs fine and needs choke to start hot.

After flat out running for 30 mins today, it is piddling black metallic oil from somewhere- it’s actually splattered all over the underside of the tank, the side of the motor and drips down the plug lead. The cylinder base gasket looks alright and the spray path makes me think the main seal behind the flywheel is gone. Bearing doesn’t sound great either so its probably cooked the seal and that explains the metallic hue.

I have a spare vacuum (of course haha) but problem is it’s in good condition so I am loathe to bin it. I also can’t replace it as the last petrol one like it on the market is 1.5kg heavier (morrison ezyswitch). The ryobi is 6.1kg dry and the morrison is 7.4kg – add 300g of fuel and half a bag full of leaves and its bloody heavy.

My question is has anyone short block swapped a 31cc motor from a ryobi whipper snipper straight onto one of these blowers? For $15 at the tip (if the thieves haven’t upped the price since last time) it would save me a lot of agro replacing the bearing, seal and redoing the oil hardened ignition cable.

I recommended it to a guy about 5 years ago as his got straight fuelled but never heard how he went
