Carbs flooding

Hello to all.

I just got my hands on my first VN 750 ('85) with 25,000 km on the clock. The bike is in great condition and has been well maintained. However, on my first ride out of town I discovered a serious carby flooding problem. I first noticed it when the bike stalled on the way home when I came to a stop. I immediately noticed a strong smell of fuel and that fuel seemed to be coming from everywhere on both carbs - actually flowing from the bike. I eventually located the leaks to where the small piston (plungers) actuated by the choke enters the carb through small rubber stops (don't know what they're called - choke sleeves?).

It was a little scary as I'd been traveling for about an hour at reasonably high speed, so the exhaust was very hot.

Anyway, does this mean that the problem is with the choke or could it be that carbs were so flooded by a stuck float that the fuel was forcing itself out through where the 'choke pistons' go into the carbs?

Also, given the serious flooding would you recommend change engine oil and fitting new plugs after I sort the carb problem?

Grateful for any advice. I'd hate to put the bike into the shop and have some money hungry mech tell me I need a carby re-build, when it's not required.

A stuck float is the likley cause. I had a similar problem. Fuel even filled a cylinder and contaminated the oil. I recommend pulling the carbs cleaning and check float levels. Clean the petcock (it takes vac. from carbs) and change the oil. The plugs may only need cleaning and gap. You'll be back out dodging those kangaroos before you know it.

Correct your float is probabley plugged, By the way if it is a 85 it is probabley a 700 not a 750.
Sorry I just looked at the pict, in the States the 85 was a 700 due to import laws.

Thanks for the replies.

I'll get the bike into the shop to have the carbs looked at and will do an oil change - I hope to have her back on the road soon.
