Francis prepared Methanol carburetors

Sick of changing jets all night? now you don't have to. This Francis Engineering prepared jetless carburetors tuning is as simple as a turn of the screwdriver externaly. We have found these carbs to outperform any other carb on the market. We have raced other carbs for 15 years. If Our carbs wern't better why would We use them? We race what we sell. We use a meetering rod desighned by us that is specifically made for the methanol burning 2 stroke. This carb really shines on the lowend as well as the highend. There is no loading up or hesitation. Air/fuel ratio is perfect at all throttle positions, These guys offer more air flow and fuel then any other carb. This is the carb that Rick Francis uses ever week as well as racers all over the country and world. These things really are fool proof and simple to adjust but usually isn't necessary. These carbs are Especially recomended for racers who know nothing about jetting, all the technical work has been done for you. Carbs come with 2 powerjets, billet float bowl and Large bell mouth. Made in the USA. Please contact us for more info.

yes, you are right, maybe it was in the same thread about oddball carbs...

There was one on the foxhat 260 in the "summer session " custom show. I think one of the mohican has it.
You need to look a bit closer mate

Just loaded a 34 up on a RB 20. Seems alright, but I don't like looking at the inside of the float bowl. Seems like the fuel is not anywhere near the "level" mark that's stamped into the bowl. Time to play with the float? Looks like it'll run out of fuel when run wide open for a while. Don't know whether you can adjust fuel intake by changing the float needle/seat. They've been around for quite a while now, why isn't everyone using them if they are that good?

I'd say the majority of RBs in the US are running Lectrons actually.

I am thinking bout putting a tillotson on my iron barrel 225 in winter as they are so easy to ser up and dial In
