Engine built but its down a cylinder, hard to start, and idles at 3000rpm

[Dean_Doherty_1990]

Hey, so as some may know from a recent thread I rebuilt a standard engine,its causing a headache....
it doesnt like to start unless I drop fuel directly into the chamber, once it starts it idles at 3000rpm and if I touch the throttle it chokes and cuts out, it is also down a cylinder

Any ideas?

what other mods do you have on it...what condition are your dizzy,leads and spark plugs in..?

You sure it's down on the cylinder bud? Have you checked by just pulling a lead off and checking if it sounds the same or have you done a compression test? Sounds like you have a few things happening there but make sure it's not an injector playing up rather than a cylinder down, seems strange to start when you drop fuel down the port but not when you try just cranking it over normally

MAP and TPS problem and Lambda perhaps?
