Re: 5.0 to 5.7 Rapido rebuilt engine swap
.........Cliffsqjet.com sells the best kits and he will talk to you forever to get the carb right. You can send it to him as well he is the best!!!
I could do it for you but you would have to ship it to me and then back so you might as well send it to him. I have done many of these carbs and only wish you were closer as I would help you become a believer in these.
I contacted Cliffsqjet.com and this is the response that I received back from them...........
We rebuild quite a few Marine units, and also sell HP kits for them. The ethanol and additive content in modern fuels is causing a lot of the old Marine units to give troubles. There isn't a day goes by I don't get a call or email about one.
We have stepped up with modern materials to combat the problems associated with currently available fuels. Simply put, NOTHING rubber will live if placed in service. We use nitrile tipped needle assemblies, and florostemer accl pump cups, with hard plastic pump assemblies, with improved springs on both ends for superior fuel delivery. Our accl pump also has a "garter spring" under the pump seal, to keep it in constant contact with the pump bore, unlike the weak/factory design.
The bad news is that we are currently at least 5-6 months backlogged, and not making much headway at getting caught up. At least 30 percent of our business is correcting issues with fresh or recently "rebuilt" carburetors. This comes directly from NOT using good parts, and not recalibrating for the loss in BTU or less energy content of modern fuels.
If you don't mind the wait, we be glad to completely/correctly build the carburetor for you. If you want to tackle the job yourself, we sell complete HP kits for Marine carburetors, $79.95 plus shipping.
Thanks,
Cliff
If my brother in law is unable to tackle the job you might just be getting an email from me.
