daverclasper Posted September 3, 2021 Report Share Posted September 3, 2021 Hi. I have read that heat shields can can cause too much heat around the starter?. I cut a piece from an old sheet of alloy heat shield I found on the side of the road. It covers pretty much the whole area under the carbs and the top of ex manifold, so I guess a lot more manifold heat will now be in the area under the carbs and by the starter. Is this bad for the starter?. It has helped a lot with whatever was causing fuel vaporization/bad running/restarting after slow running in hot weather. Cheers, Dave Link to comment Share on other sites More sharing options...
Pete Lewis Posted September 3, 2021 Report Share Posted September 3, 2021 with a std exhaust manifold i dont think that would be a problem on a 631 tubular it can be close i made a shield to cover the end of a hi torque on mine starters will get as hot as the engine , they are close too and bolted on the back plate this transfers all the heat into the starter which is made to withstand as such Pete 6 minutes ago, daverclasper said: fuel vaporization/bad running/restarting after slow running in hot weather. this would be more to do with being too rich at idle than vapourising getting upset by high under bonnet air temperatures or a too slow idle and less fan speed Pete Link to comment Share on other sites More sharing options...
