Title: 87 carb flooding?
Post by: Ales Porter on April 13, 2008, 11:51:24 AM

Help... Not sure what the problem is but am leaning towards a "Float" problem in the carb. Regardless of the driving conditions.. at times the engine will begin to lose power and shutdown.. at times I can apply more accelerator pedal and avoid engine shutting down... However... as of late I have noticed the strong smell of gasoline ... I had to let it sit for 10 minutes before she would start up again... anyone else experienced this problem?? I have checked vacuum hoses, spark plugs, no fuel leaks, idle is good,...

Is it worth a rebuild or switch to a different carb?

a minor overhaul kit is pretty cheap, and may fix your problem.
there may be a fault with the float valve?
costs much less than a replacement carburetor, and you still have that option.
i am not a fan of buying "rebuilt" carbs.

Thanks for the input rascott. I removed the carb yesterday to rebuild. Will tear down and check the condition of the float valve, etc..

I concur with Rascott, the problem is almost certainly to be found in the float/float needle and seat assemblies..

In all probability its probably just some crud (usually varnished gas) in the needle seat making the seal unreliable..

Ive fixed a few of these by applying valve lapping compound on the needle, hooking a rubber tube to it, then spinning it in the needle seat with an electric drill, just like lapping a valve, but easier as the brass is softer.  Its an old Mikuni trick and gives perfect results if you see a nice shiny new seating area on both parts.  With the multi carbed Jap bikes a set of 4 needle and seats go for about $150 bucks, which gives incentive to just regrind them vs replace them..  Ive repaired hundres of motorcycle carbs this way, and a few of the carbed Samuris too.

Make deadly certain too remove ALL off the lapping compound..

Thanks Dennis for the great suggestion. I'll inspect and perhaps that will be the solution.

i recently rebuilt athe same carb on an 88  and the kit was about sixty bucks    not to bad   and it was really easy   just make sure you keep track of all the parts   there are some pretty small ones
