Big Block engine idle without moving

Rahalla172 · 05-21-2014, 10:34 AM

I just installed a big block enign in the ol' 97 yamaha, runs great however is there a way to have the engine running without the cart moving until I step on the gas? To me using the starter to get the cart moving seems a little off. I would think that you should be able to start the engine and it idle until you accelerate. Is my thought process correct? do I need to do something different with the clutch, or the idle speed

The cart does not idle at all? You mean it runs just like a stock cart? Something doesn't seem right. All big blocks I've seen have idled...

it idles, however the cart wants to move, For exapmle when I come to a stop it kills the engine. I would think that it should Idle until I shut it off and the reverse on the start up

which clutch are you running and is the belt to tight ?

Rahalla172 · 05-21-2014, 01:15 PM

That's a good question, let me go about it this way, what should I have as far as a clutch? the belt is 45 inches What size should I be after

well that would be the wrong way to go about this cause just about every big block install is different send us a picture of your clutch setup and we can go from there you either have to the belt to tight or you have a stock clutch without an idle spring , or your primary clutch is not disengaging ,also do you know what your idle is set at , it could be pulling because of to high of an idle speed

I havee attached some pictures. After I got to thinking about I don't have the factory clutch on there. It is a highperformance clutch that delivers more torque. When switching engines I asked about that and the tech rep said that there would be no issues. Should I have the factory clutch on there or a different spring.

CAN you get us a picture from over top looking down at the clutch on the engine , from what i can see that belt is wearing due to being to tight and the deflection that you show pushing on it is a definiteindicator , if i read that belt right it looks to be 41.5 inch belt you probably need at least a 43 if not 44

I will work on getting that Picture, thank you. what would be the part numbers? I have a 10978 belt that is 45 1/2 outside diameter on the shelf but if it needs to be bigger I will get that ordered today while I have time
