I received this carb kit as promised. It is a complete kit for this carb. It was great that both accelerator pumps were in the kit because ther is no way to tell which one was needed till the carb was disassembled. Great price and no hassles. Thank you!!!

I wish i would have found mikescarb earlier. it would have saved ALOT of problems and $$$. i wound up buying seperate parts because the supplier said no master kit was available and i wound up buying individual parts at a huge cost. lesson learned? Get parts from Mike !!!

I really like this carburator kit, it came with everything that I needed to rebuild the carburetor. One other thing that I liked about it was that it came with both accelerator pumps. I would highly recommend if you're going to build this carburator to get this kit. It's a lot cheaper than I've seen on other sites and still comes with everything that you need.

This kit had everything I needed to get the job done. The online videos helped me completely re-build the carburetor on my 1992 Sea Ray. This is worth noting because I had never done this before. Great customer service when I called in looking for the correct parts etc. Glad I chose to order this rather than search at local boat stores.

carb kit

The service was great and the delelivey was even better but it did not fix my problem. My 4.3 mercruiser starts right up and within a few seconds stalls. I have to pour fuel into the carb to get the electric fuel pump to kick in an then it runs perfect all day.The fuel pump should kick in with the key in the on position. it might have something to do with the oil pressure safety switch, but I am not Sure I think I might need another part. It is a 1997 4.3 lx gen 2 with a 2 barrel carb s/n ok191027. Any help would be appreciated. Fuel pressure is great once I get it started so I know fuel pump is working once I get it running. Again thanks for you service and I would defintely do business with you again. Please help. Ed

Top quality kit with everything you need for a comprehensive rebuild. Instructions video was great also! I highly recommend this kit if you want to resurrect your carb's performance. Would only suggest one additional thing. Instructions on how to adjust the idle mixture for peak performance would be great.
