running horrible

ive got a 1990 B2200 carb.

it doesnt want to idle at all it idles at around 200 which i know is super low.

it doesnt get better even when the engine is at oprateing tempature.

it pops and back fires like crazy... it sounds like a machine gun its so loud and often.

and i can barelly drive it i keeps like stoping and going when im giving it gas.

and it dies every time i push in the clutch to come to a stop.

and after i take off it feels like i have no power, like im running on 2 pistons

also once i take off around 2300-3000 it sounds like a constant back fire like i lost a piston or something

so theres the problem i need help, ill clear um anything just ask

have you checked your plugs? also check your timing

Dude i had the same problem except mine added the additional Extermenating the Masquitos with my smoke lol.... man it blew i out the exhaust.... but i put new plugs and ajusted my timing... nothing i had NO CLUE so i actually broke down and had someone put new seals and bearings and check if i had a burnt piston. he said my pistons were fine but my bearings were shot so now my truck runs great not bad considering i only paid 500 bucks for that, new gaskets and new hoses everywhere

ill check the plugs and post what they look like and how do i check the timing? and adjust it?

tune the truck up with new plugs,wires and dist cap and rotor button.Mark on the crank pulley should line up with a mark on a flange built into the block of ur truck.the crank pulley mark should be 6 % before the top dead center mark (BTDC).u need a timing lite with one wire hooked to the number one plug wire and the other wire hooked to the battery.Auto Zone or most good parts houses will check it for u .To adjust loosen the top bolt on your distributor.Move the dist toward the front of the truck to retard the timing,toward the back of the truck to advance it.BJ

ok the plugs are good and i havent got to check the timing

Sounds like a Accelerator pump in the Carb. The greater inertia of liquid gasoline, compared to air, means that if the throttle is suddenly opened, the airflow will increase more rapidly than the fuel flow, causing a temporary "lean" condition which causes the engine to "stumble" under acceleration (the opposite of what is normally intended when the throttle is opened). This is remedied by the use of a small mechanical pump, usually either a plunger or diaphragm type actuated by the throttle linkage, which propels a small amount of gasoline through a jet, wherefrom it is injected into the carburetor throat. This extra shot of fuel counteracts the transient lean condition on throttle tip-in. Most accelerator pumps are adjustable for volume and/or duration by some means. Eventually the seals around the moving parts of the pump wear such that pump output is reduced; this reduction of the accelerator pump shot causes stumbling under acceleration until the seals on the pump are renewed.

sounds like it jumped timing to me

Everything sounds like jumped timing to you Todd, lol.. (i just read like 3people have engine problems, and you've said it) LOL... but who know's, you could be right.

okits fixed thanks to adjusting the timing but, u said to turn it torwards the front of the truck to retard the timing, but i have a hanes manual that says if the timing is to retarded that the truck will stumble and have sufficent power loss (my problem). but to today i adjusted the timing forward (retarding it) but it helped? so i would think that it would make my problem worse but it didnt, it fixed it so im wondering how it got fixed?
