| Okayguys bought a 74 Thing from a fella and it seems to be running a tad hot. When I first got it, it was pinging under load and I soon found the previous owner had set the timing on the 009 to 28 degrees at idle and the valve clearance to 0 basically, reset the valves to .006 and the timing to 28 degrees advanced at 3000rpms, It runs better now and does not lose any power, However the chrome dipstick is too hot to touch after a short 16 mile easy drive. A thermometer in the dipstick hole on shutdown reveals a temp of 228 degrees. It has chrome tin through out the engine and all the seals and doghouse cooler parts are in place. I bought new original tin and a Berg dipstick to monitor everything. The previous owner left the heater boxes on with a type 2 exhaust, however he has a 36hp shroud with no heater outlets on it, no air is moving through the heater boxes, I ordered a new thing exhaust with J-TUbes and Have the industrial tin to fill the void left by the removal of the heater boxes. My question is would the heater boxes cause an slight overtemp when there is no cooling air flowing through them? Can I expect a return to normal temp with shedding the Chrome tin for black and using Jtubes instead of the heater boxes. Thanks for any input |

| I think if you go back to stock tins and get the un-cooled heater boxes outta there in favor of j-tubes, you'll probably drop some temp. I've heard that heater boxes without air going to them is a no-no. |

you are on the right path.
What is the carburator that is on the engine? You could get an SVDA from aircooled.net to help cooling and mpg while you are in there.
