Chassis started yesterday but will not today. I have spark at coil and plug. Cleaned carb (new Tilly) again. Using a new lawn mower plastic tank as a temp. Turn on, Retard, Pull choke for a few revs with GAV opened half, push in choke, crank and no start. Waiting for battery to charge up again.

are you getting fuel to the carb? if so unscrew the drain plug to see if fuel runs out....
make sure the fuel line is not to far past the ferrule, I like about a 1/6th -
I checked bowl and yes there is gas. She started this time but she sputters. Give it some throttle and she cuts out.

Gav helps a little...should I mess with air screw?Comment

I did time it again....thought I'd try the Nu-Rex method.Comment

So, was the 'Nu-rex' method the reason it started or didn't start ? And, yes, the idle mixture usually needs adjusting. GAV, I don't know what opened 1/2 means.[ Does it mean 1/2 turn or 1/2 way]. Tilly's require opening the GAV generally more than Zeniths. They normally need 1/2-1 turn out [ ccw] when warm which means an extra turn out for a cold start. Make sure the 2 venturi ports are clean as well as those in the main jet. That jet can be a royal PITA to remove sometimes.Last edited by Patrick; 05-06-2017, 07:46 PM.Comment

Beauford,
I have a Tilly that won't run less than 3/4 turn out on the GAV. I know you'll hear a lot about number of turns out on the gav but what really matters is the fuel to air ratio. Number of turns is relevant to each individual carb. These things are 80 years old and probably out of spec. You've got the right idea about fuel, O2, & fire. All the engine knows is when the mixture is around 14:1 (also timed correctly) she's going to run. Stay with it and it will seem simply when you figure out what's missing,
good luck,
HughComment

when Tom W has time we are going to hopefully get a nice easy tutorial with pics of setting the timing easy and properly.
im not saying u didn't do it right, just mentioning something that would be nice for forum reference
I usually go 1 to 1 1/2 out on the GAV for a cold startComment

sounds lean....something clogged somewhere.
Take fuel line off carb, open gas valve, and see if you can get a really good stream.
Also, it never hurts to mess with the GAV, let'er rip, open it up, once it starts and warms up you can dial it back until you find the sweet spot. The GAV enrichens all the jets in the carb.....
what happens if you hold the choke out a little bit to enrichen in that manner??? Try that before anything else I've said
fresh gas we presume
i had a tiny spec of crap jam my needle and seat on a tour, had to pull off the road by holding the choke nearly all the way out. Removed carb, started investigating, and yikes a small piece to crud fell out into my hand when I unscrewed the float valve. Thankfully an easy fix. My tank is clean, tooComment

About to take a 10lbs sledge to this Tilly.....now its dripping gas out the intake. Waiting on battery to charge...Don't know how old gas is but my Cub cadet fires right up.Comment

No, I had just bout the Nu-Rex months ago and thought I would re-time to see if that would do anything. It did not and was timed correctly before that. It has to be a fuel problem. Fellow A'er has a tilly up the street. Maybe he can figure it out. Pretty simple freak'n carb....Originally posted by Patrick View PostComment

When you drive these cars, do I assume you mess with spark adjustment with the RPM's? Can I just position it about two clicks down and leave it?Comment
-
"I assume you mess with spark adjustment with the RPM's"
correct. If you leave it 2 clicks down at all times it will be retarded for most of your drive and the motor will overheat quite quickly. A retarded motor can come to a boil in about 5 min. Pretty impressive, actually
Most usually run about 3/4 of the way down most of the time, and retard it a bit going up steep hills. Different owners will have slightly diff. techniquesComment

Well, Tbird, your great knowledge has spread across two forums! You sir have solved yet another puzzle. Maybe that is why my engne runs hot.....I will do as you suggest on my Sunday chassis drive alluding the police! Thanks!Comment

36 V8.
12v setup.
I had it running a few times now but it is a real pain to get going.
I accidentally left the key on and drained the battery, and in the process burned up the coil. Just put a new one on and have spark now. But for some reason all it does is sputter and backfire out of the carbs.
do any of you guys have suggestions for what to try next?

Ok, this morning I took a 30 mile round trip to Ron's Machine Shop in Shandon, OH to show them the car. Stopped on the way home and filled up with 5 gallons. We jumped in tonight to take a short drive and less than a mile from the house it started sputtering and finally quit. Got it started with choke and it idled for a while then quit. Pushing on gas pedal it is starving for gas. I am pretty sure...09-16-2017, 09:32 PM -
First thing to do is check for a nice blue spark, most of the time if the car has been running ok, then it will not start or try to start you have no spark or a weak spark.07-09-2019, 08:37 PM -
I have fuel flowing to the Zenith carb, fuel bowl was full when I removed the carb. Float and shut off appears to be working normally, not sticking. After attempting to start had no fuel on plugs when checked. The carb worked last time I ran the engine about 10 months ago. Any ideas?11-11-2019, 08:37 AM -
When I got my coupe back after it had been sitting for most of 9 years, one of the first things I did was flush the gas tank and when that was done, I bought a rebuilt Zenith 1 from Bert's. The car ran beautifully, but I haven't driven in much since getting it going. Several weeks ago, I was going to go to a local cruise and it quit after just a short ride. It felt like fuel and I concluded the the...07-08-2019, 08:57 PM -
my project 47 ford pickup starts fine and I’ll drive it into town and shut it off and it won’t start unless I wait 10 minutes as it cools off and then it starts and when I get home it does it again. What could my problem be?06-05-2019, 07:12 PM

I was having some issues while driving my 29 Leatherback a couple of days ago.I hadn't run it for about a month. It was running a little rough at first, but after it warmed up-it started acting like it was starving for fuel. I barely limped home with the choke pulled all the way out. If I put the choke in, it would die. I fiddled with the spark advance and the GAV, but that didn't help. So far...10-30-2017, 06:19 PM -
Didn't have time really but, checked her plugs again, points, carb checked out OK and change out old gas for new. Had spark also, battery strong but nothing!!!!!!!!!!! So!!! only one thing left to do and I should have done this first. A little WD in the carb intake and away she went...…..png "thumb up")

I drove our '21 Touring for the first time in about six weeks today. The engine has been completely rebuilt and has about 30-40 hours on it since. I drove it about a mile to a local store and filled the tank with gas. It ran fine going there but not so good coming home. My first thought was "water in the gas I just bought". However, after I made it home I found, by grounding out each plug...10-27-2019, 05:09 AM -
I have a "friend" of mine that is having a problem that has me, I mean him, puzzled. The car idles great. There is a response from the timing lever. Starts off smooth as silk. In third gear, at about 40-45 the car hesitates then resumes, hesitates resumes. The engine RPM's go down like you took your foot off the gas but it sometimes backfires out of the exhaust, so not clutch related. This...10-20-2018, 12:03 PM
