TOPIC:

I have yet to set my floats wet. Always set them dry at 25mm, upsidedown, from the gasket surface. I have mixed & matched three sets of carbs and have experienced only very minor problems. They all run somewhat rich but, other than that, no apparent bogging or hesitation.

My question is....Will a bad float setting affect only hesitation and/or flooding OR, could it affect richness/leanness? Thanks.

I can't believe no one knows the answer to this?

Yes... Setting the fuel level as you do leads to problems.

Thanks.

The float level affects the fuel mixture. The higher the fuel level, the richer it will run.

Bemoore,

Thanks. That's kinda what I was looking for.

There should be a carb FAQ list on the site somewere. I understand bits and pieces, what happens when this is done to that, but i don't have the "big picture".

Made myself a jig at the weekend, out of some 3/4" plywood, to hold the rack square and level, in the vice. Purchased an old generic, plastic (Yamaha?) gas tank, with basic petcock, ($6) a year or so ago on Ebay. Hung it from the shed rafters and used a 6' piece of fuel hose to feed the carbs. Also took an old float bowl drain screw, soldered a brass 1/4" barb fitting to it and drilled through the whole deal. attached a 10" piece of clear fuel hose to the barbed fitting and I had all I needed to do the wet setting. Dit #1 & #2 at the same time then #3 & #4.

All float levels checked out right on the money but the bike ran like shyte. Still fouling plugs on #4.

Looks like I'm going back in to find the broken oil ring on #4 I keep telling myself I haven't got!
