Mc2150

Just ordered a MC2150 from the carb guy on eBay. Just wondering if there are any tips or things to look out for on the install. He says that his instructions are easy to understand but just figured I would get the advice of the oracles on here. Thanks

Very simple to install. Your carb will need tuned so you will need a vac gauge and the knowledge of how to use it (most vac gauge kits come with good instructions). Before installing, check that the float level is set to 7/16" and set the idle screws 1.5 to 2 turns out. This will give you a good start tuning.


You may need more than the basic tune, the ebay guy does not always send with the proper jets and powervalve (both needed changed on mine, and others have had the same issue). If you have never tuned a carb before, do lots of research on what to look for and symptoms of an improper tune and what they tell you; ie. bogging, hesitation, surging, fouled plugs, high idle, etc. Lots of tuning and rebuild guides out there on the web. Good luck!

Thanks gents. I will have to do the research on how to tune it and troubleshoot. I have the diagram of the vac system but once I actually look at it under the hood it looks like a bowl of spaghetti.

I put mine on it started right up and runs fine out of the box. Just make sure there are no open vacuum lines open. I think you will be impressed. What a difference great idle
