JDC_747 Posted October 7, 2021 Report Share Posted October 7, 2021 Hi chaps I've done the valve clearances and the static timing, both as per the Macy's Garage instructions. Having read posts on here regarding unleaded, I've set it to 8 BTDC rather thaN 4. I've also checked the distributor, weights are moving ok, springs are in place and all looks ok to my noobie eyes. Set points to 15 thou. Cleaned rotor arm and removed and cleaned/checked/gapped plugs. Plugs were all ok, 3 & 4 a little darker, possibly running a tad rich? Was then able to get idle to a fairly smooth 850- 900 rpm. Anyway, went for a good run this afternoon and noticed the temp gauge was higher than before, higher than when run last week at same air temp and a long run with some traffic. It's not overheating by any means, but moving up above end of the 'normal' range, see photo. I've not pulled the plugs yet to have a look (too hot!), what could this be? Is it something I may have accidentally done under the bonnet? Thanks in advance for any help and advice.. Jeremy Quote Link to post Share on other sites
JDC_747 Posted October 7, 2021 Author Report Share Posted October 7, 2021 P.S plugs were gapped to 25thou, champion 6HYS iirc Quote Link to post Share on other sites
stuart Posted October 7, 2021 Report Share Posted October 7, 2021 Too far advanced possibly wont help, 4 degrees is nominal. Stuart. Quote Link to post Share on other sites
JDC_747 Posted October 7, 2021 Author Report Share Posted October 7, 2021 Thanks for the quick reply Stuart, I'll put it back to 4 BTDC. Jeremy Quote Link to post Share on other sites
lynchpin Posted October 8, 2021 Report Share Posted October 8, 2021 Hi mine has the bypass hose restricted and an 82deg stat the gauge normally sits about were your photo shows, but as Stuart says I think 4deg is correct, (according to my mech brother).

JDC_747 Posted October 10, 2021 Author Report Share Posted October 10, 2021 Hi Stuart, once again great advice, back to 4 BTDC and temp now comfortably where it was before - thankyou. Hi Phil, having read a few posts, the bypass restriction seems a good idea. I plan to use a couple of inches of smaller diameter hose in the bypass but what worked for you?

Jeremy You dont need it on a 4a as the bypass boss in the water pump housing is already of smaller internal dimensions. Stuart. Quote Link to post Share on other sites

lynchpin Posted October 12, 2021 Report Share Posted October 12, 2021 Hi Jeremy I used a 22mm copper pipe blanking cap ( I am a gasman after all) drilled a small diameter hole prob about 1/4" and pushed it into the hose to the bend its a tight fit so quite a good seal to the hose..
