adusting needle/ adj needle housing
for tillotson x carburetor
ques 1. prior to screwing in housing into lower carb body, do i need to retract needle all the way out in the housing? seems like if i don't, i will injure seat or needle tip quest 2. if i retract needle all the way out, and i try to seat the needle after screwing housing in , will i be able to screw needle in without injuring seat or needle tip? will i be able to 'feel' when needle is seated? ques 3. after i seat the needle, are there a certain number of turns out that should be made for initial setting like for example 1 1/2 turns out? ques 4. snyder's and mac's have pictures of zenith, where can i find any pictures of a tillotson? thank you |

Re: adusting needle/ adj needle housing
The vendors have a very good Tillotson repair and restoration manual. If you have the item and want to repair it, having the information is a plus. There are articles in the Restorer and Marc magazines.
The Tilly is kind of fragile so back the GAV out and when installing the housing screws don't use a lot of force in the screw driver. When installing the GAV needle, go slowly and you will feel it contact the seat, stop there when you just feel contact. |

Some guys won't run anything but a Tilly. I know a guy who has five A's/five Tillotson's. They are a good carburetor.
