pinging suspect new manifold
Gray-man:
Hi Guy's Just letting you know,I spoke to Mike George from Long Jetty Auto Engineers who told me my dual plane manifold was not suited to a rochester carb because the divider between the high & low sides dosn't come all the way to the top of the manifold about half an inch lower than the carb bolt on surface & this often will make a motor ping ,he had a second hand Weiand one that he sold me for a very fair price and said he would refund my money if it didn't fix it so I put it on & it works great problem solved I even took it back to show him & he timed it spot on for me so Im back on the road & happy

Thanks for the update. Sounds like he looked after you.
Doesn't the stock manifold have the "step" in the divider??
