I have a 1998 3000SCR and one of my engines (STB) has an acceleration problem. I just had the carb rebuilt so it's not dirt. It idles well but as soon as I try to accelerate (slowly or quickly), the carb seems to starve of gas and begins to stall. I have to kind of pump the throttle and wait for it to start accelerating and then I can continue accelerating.
Also, I have trouble maintaining anywhere from 1000-2000RPM, it'll drop back to idle.
I suspected a timing issue or maybe a vacuum leak?
On the timing issue, I tried to locate the timing angle plate and I can't find it on either engine. Enclosed is a photo of where I thought it was but I can't see it. And even the service manual doesn't show it's exact location. Any ideas on the acceleration problem or on the location of the timing angles?
