1987 Honda CRX shuts off when worm

When it refuses to start do below to determine if its fuel or spark then comeback

Get a starting fluid or ether and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it

It Warms up and stays on now i found out that the primary fuel filter was bad it had dirt in it and when they had put it on they but it on soo tight that it nearly pinched the inlet tube shut...now it runs and dies again but i can keep it on if i have my foot on the gas and when i let go its satys on but at 3000 rpm i adj. the throtle cable and got it as low as i can get it with out dieing on meand that is 2200 rpm ne thing lower and it dies...... how can i lower it???
