Resolved using the "checkout_cart_save_after" event

<?php

namespace ModWay\mod\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;


class ProductCart implements ObserverInterface
{
    /**
     * Below is the method that will fire whenever the event runs!
     *
     * @param Observer $observer
     */

    public function __construct()
    {

    }
    public function execute(Observer $observer)
    {

        $cart = $observer->getData('cart');
        $quote = $cart->getData('quote');
        $items = $quote->getAllVisibleItems();

        foreach($items as $item)
        {

            if($item->getSku()=='MSH09-32-Black'){
                $item->setCustomPrice(8);
                $item->setOriginalCustomPrice(8);
                $item->getProduct()->setIsSuperMode(true);
                $item->save();
            }

        }
        $quote->save();
       // $quote->setTotalsCollectedFlag(false)->collectTotals();
    }
}
