- 1989, rebuilt Mercruiser 454, 100 hours
Hello CSR!
Hoping somebody would be able to help me with this...
I have a choke issue I believe in my twin 1989 7.4 454's with I think Rochester carbs. If you look at the photo I'm pretty sure the choke flap is supposed to be completely closed not half way like mine is. Is there a adjustment? Photos are while engines are cold and haven't been ran in a week. Throttles were just pumped before the photo. Harder to start the port engine than the stbd and the port is running a bit rough for the first 4 mins or so until it's warm. The rpm has to stay above 1300 for it to stay running and not stall when cold. the port engines choke flap is the one pictured, the stbd choke flap is more closed and runs great cold. Any help at all is appreciated! And the engines were fully rebuilt 40 hrs ago. Engines run perfectly with no hiccups when warm. Thank you in advance!
