I happened to have the bonnet (hood) open when I was starting my 1915 Tourer and noticed that, as I turned over the engine (motor) with the choke pulled out, petrol (gas) was coming from the hole underneath the bowl. Looking at diagrams, this seems to be an overflow from the needle and jet. It looks like the pistons are pulling in too much fuel which rises above the overflow hole. Is this normal or am I cranking too much? (4 pulls). Otherwise the engine runs well.

Re: Holley G starting overflow?
I'd say it's not "abnormal" . . . perhaps you are choking too much; all T's respond differently, but two pulls "cold" in summer weather is adequate to start my '13 with the Holley G carb. In cold weather, three or four might be required. Perhaps your float level is set a wee bit too generous ? You can see the "puddle" in the main jet seat by removing the three screws and cover which holds the needle; there should be roughly 1/16" of fuel covering the end of the "strangling tube". Back the needle out several turns before removing and replacing the cover, otherwise the operation may damage the needle and/or seat. If all is well, I wouldn't be too concerned. I have always had good results with the Holley G !
