carb cleaning

How easy is it for a novice to clean a carb out, watched a vid on youtube and it doesnt seem too bad............

Any tips?

If you're thinking of doing it on your Parsun, isn't it still under warranty?

no unfortunatley not, bought it second hand and have already had to spend £60 on a fuel leak and its better but still not quite right. Wouldnt get past half throttle the other day for half an hour or so. I rang the importer for Parsun in the uk and they suggested that the carb needs a clean. The thing is, i dont want to spend anymore money on the bloody thing and am too honest to sell it on knowing that it isnt behaving properly!

Depends on the carb, some strip them down and then put in an ultrasonic cleaner then rebuild, it's getting them rejetted properly that is the trick.

I would start with buying a manual for the engine, it is not a hard job, why would he want to rejet a carb ??

Well.........took it off the engine, cleaned it all out with carb cleaner, just put it back on the engine and have a small fuel leak!, off again, striped apart again, now trying to re seat the gasket between the bottom and top half. It seems to have grown for some reason so now in the freezer trying to shrink it back again!

Think you might need to get a new carb gasket.

Is this the model? http://parsun.eu/outboard/spare+parts/F9.8/CARBURETOR/

I think you will find you need strip it down an soak it for a bit longer than 3 hours, leave it over night, and make sure you remove all plastic and rubber gaskets, as for gaskets growing you sure you haven't over tightened the screws, I would order a carb kit monday along with a manual, or you willend up ordering a new carb

Got it all back together, still a small leak so new gasket required. Trouble now is that the water in the tank is full of carbon deposits, all over the prop etc. I take it i have adjusted something i shouldnt have?
