Everything has been running fine after getting this truck back to normal. But now when I push the accelerator it stalls or does this. Anyone experiencing this or has in the past please help.
Recently finished replacing a lot in the engine bay and recently put in a new carb. The last Weber carb that was in this truck I was able to tune it. But with this new carb I'm having trouble with it. It keeps dieseling out but anytime I bring it down the idle gets rough and I just can't find the sweet spot. Any help with how y'all got yours tuned right? I do have a timing light as well to check rpm.
Also yesterday I did the valve adjustments everything seemed fine. Spark plugs look fine as well. I've recently had issues on this truck around the same issue that I've posted about. I finally had time to do a compression test. From front to back.
1-180psi
2-165psi
3-30psi
4-30psi
What do y'all think I would have to replace? Do I have to take the the whole head off to see? Also while doing the test 3 and 4 it sounded like a big puff of air shooting out the other holes. Louder then when testing 1 and 2.
I kinda smoothed out the idle in nuetral. So did a lil test run and now this is the sound it's making, it doesn't make that sound when revving in idle. Are these the valve rockers making this noise. Just need a second opinion on it. Thanks
A little backstory, after driving on the highway for about 15 minutes, I started to suddenly get a rough idle while having my foot on the throttle somewhat lost response and put it in neutral while on the highway and was having rough idle on and off gas. I've checked the timing chain looks fine. I've changed the fuel filter, fuel pump and all spark plugs, coil lines, ignition module distributor everything electric basically. It runs smooth only in high Rev. I still need to do a compression test as well. I've checked the vacuum lines I'm not familiar how but they look fine. Any ideas?
Edit: I adjusted one of the screws on the air/fuel mix. It's calmed down slightly but now when I'm accelerate it the exhaust is making a lot of pops
I just connected this line that was already connected to the Weber to the charcoal canister. Is this right? It wasn't connected before so just wondering if it does.
I have the the crank pulley at 0° for my 22r engine. I'm trying to figure out how do I know the timing chain is at the right spot at 0°. The guides look fine. A couple weeks ago My truck after driving about 15 minutes. Started to run rough the motor was shacking heavily on throttle and heavily shaking at idle as well. After awhile the engine turned off like a it stalled. After pulling over Vacuum lines looked fine. carburetor seemed to be getting gas as normal. I was asking chat gbt it said perhaps ignition timing or timing chain. Any help would be appreciated.
