i clear everything with 1/16th clearance at the least; i'll get a pic of the new throttle set-up
If it's hitting internally then thats all it can do!

If you have slack then yes. This write up has more to do with getting full internal travel out of the pump. The dimmensions of teh stock lever wont allow that.

i stacked 5 washers behind the retainer on the pedal and switched the holes in the lever, it came CLOSE to the fuel line but it wouldnt hit. i actually need to throw one more washer in the mix.

and yeah i figured if it was hitting internally there arent any modes for that although i do need that 366 spring and an upgraded fuel system. i'm pretty sure i'm taxing the stock fuel system as is. good nows is; its got a brand new LP. bad nes is it's still a diaphragm style. i like the low pressure piston pump idea but it's 1/2 the price of an airdog

i tinkered with my pedal to day. took off the to nuts to the go pedal bracket on the floor board. stuck washers behind that. lifted it up about a 1/2 inch.
then cut a nut with a hack saw to put behind the rubber washer on the cable. cremped it back. . took up about 1/4 of an inch.. so now i can hit full throttle. and still have a hair before it bottems out to the floor. so is there a way to bend the ear on the pump. for more max fuel.. be patient with me i am learnen.. about the ve
