4pt & deep water
Having owned a 4pt for a couple of months, I was less than impressed with its deep water (2ft+) abilities & gained some decent exercise in pushing it out of fords!
The culprit seems to have been the two 'breather' hoses routed out of the side of the carb - moving them up high (out of the water) & the bike's transformed - it's almost a submarine!
I'd be grateful for a technical explanation as to what these hoses are for & why my *fix* works.
Thanks
Bish

It's the common "breather" problem : when submersed in water it stops the flux of gasoline in carburettor! , you have already guessed and fixed it , but for a more definitive solution : let the breather in original position , but add a "T" joint and an additional tube to be fixed to frame slightly below the airbox (so to stop the engine BEFORE the water goes into..)

Thanks for the info - obviously a good idea to place below the airbox in the event of a complete submergence.
Cheers

usually there are seven hoses connected to the primary carb.
- one is the fuel hose and three are connected to secondary carb, we don't talk about these now.
- two hoses on left and right hand side of primary carb. these are breather hoses for the float bowl under normal conditions. but if your bike falls down and lies on either left of right side, fuel will leave the carb through these hoses (instead of filling the cylinder with obvious dramatic consequences when restarting the engine, in the worst case).
- one hose connected to the bottem of float bowl. this is the overflow of float bowl. fuel will come out here if float needle valve is blocked and permanently open. or, if you open the drain screw on bottom of float bowl, the fuel will drain through this hose.
hope this helps,
regards
