if you have a bottom-pull IDA (fuel inlet facing passenger side), I can take pix of u can wait until tomorrow, I can take pix of my set-up for bottom-pull IDA.

For top pull, that is kinda complicated to make. I dont own one, so I didnt pursue making one for it.

I made my own OMP 'rod' using safety wire. It's a bottom pull IDA so I hooked one end of safety wire to the unused linkage facing the front of the car. Other end of safety wire to the OMP lever. Pretty easy, just adjust the length to work right, make sure the OMP lever moves once the throttle moves.

you dont need to buy that crap. A wire clothes hanger, welding rod or a oil dipstick will work

When I made a mop rod for the Mikuni, the 1st gen one was too short so I used a 2nd gen one. It's longer and thicker so the hole on the mop lever arm needs to be drilled larger. Just takes a little rebending, shortening and drill a new hole for the cotter pin.

as wacky said i fitted my carb fuel side out, put a nipple in the top of my 51IDA and made a ali block to take the 2 omp feeds into 1 line and into the carb, used the stock control arm and just bent it to suit, i'm not on my computer today but do a search under my name and 51IDA you should find some pics

Just increases the mix a little, may foul plugs easier, more smoke in the exhaust. Too much can lead to earlier/heavier carbon build up so don't forget to Seafoam.

As RX7Doc recently prescribed

Been covered.

Time to brush up on the search skills.

Use terms like wacky or IDA, or fuel bowl.
