Husqvarna / Kawasaki problems

[cuslog]

Hi Guys; :
If this is the wrong forum to post this in, I apologise.
I'm having a problem with a Kawasaki engine in a Husqvarna Riding mower.
Its the FH 430V 15 Hp engine. Only 115 hours, 5 years old.
It seems down on power (lugs down when mower is engaged and / or going uphill). Plus I'm getting alot of gas in the engine oil. With a couple hour's running, the level in the crankcase will go up about 1/2 a qt. and gas consumption has gone up.
Seems to run OK, no excessive smoking.
I've checked the throttle and choke linkages, they seem OK.
The fuel pump will hold a vacuum if I suck on the vacuum port, so I think that's OK ?
I asked at the local dealer and they did say something about some Kawasaki engines having "issues with blowby".
Anyone else experience this ?
Thanks in advance.
Howard

Sounds like a carb float issue.

Thanks for the reply.
I've had the carb apart and cleaned it carefully with carb cleaner, blown out all the passages I can see. Needle and seat look OK so, I didn't replace them.(it was actually quite clean when I took it apart).
I put a tach on it and found that it was only at 3200 RPM at WOT so I reset the governor so its at about 3650 at WOT now.
The low on power issue is gone, not sure about the gas in the oil though.
I haven't had a chance to use it, its been rainy and cool up here for the last couple of weeks.
If I'm still getting gas in the oil, I think I'll try another fuel pump.
