Fuel bowl size? Making it bigger, IDA and DCO
 

I have a 51 IDA Weber and I need to enlargen the fuel bowl area. I will be running E85 through it right now and down the road i will be running pure methanol (alcohol) through it. I am unsure how much I will need to add to the fuel bowl and what will the effects be of over enlargening it? Does this effect on how I set the float height? or anything else?

One other thing. I thought about swapping to the larger factory 55 dco (side draft) weber, but I am unsure of how to make that bowl larger. I don't really see how it could be done on a side draft Weber. Maybe adding a separate reservoir off the side of the block above the Webers and letting it gravity feed into the bowl with large fuel line?

Ant help here would be great!

i dont think a sidedraft is possible... but the downdrafts i know can be and a company makes some huge carbs already

visually this should help for the ida

Yeah, those are the carbs I pan on getting in the future. But for right now I'm going to use my 51's because it's what I have.

I know how to enlargen the bowl, I'm really looking for how much fluid should it hold? add 10%, 20%, or more fluid volume?

here is some mods i just did to a customer's IDA
float level should not need to change when enlarging the float bowl.

you need one of these massive needle valves and a proper fuel inlet too :)
