I thought an update might be in order.
<div>Thank you for all the suggestions and ideas. Spoiler - still not fixed.=

<div>I have removed and cleaned out the bowl/jet lines, the front had black d=

<div>Could not find any vacuum leak. I=E2=80=99ve had the manifolds off and b=

<div><br>
</div>
<div>A couple of replies were pretty confident that I have an ignition vs fu=
el issue. As I can=E2=80=99t find any fuel issue, I now suspect they may be r=
ight. I run Petronix ignitor 1149 with their coil 40611. This is the correct=
3ohm set up per Pertronix.</div>
<div> I purchased a new coil from Amazon - but the replacement coil was=
defective and had a misfire from the start which I could ABA with the old c=
oil. Talking with Pertronix the were concerned my new part was not theirs, a=
nd maybe a cheap copy - I returned
to Amazon, now waiting on a coil from Pertronix direct.</div>
<div>As I=E2=80=99m playing with ignition now, what are you guys using for s=

<div>Thank you for the advice and support - it will be sorted.</div>

<div dir=3D"ltr">=EF=BB=BF Hi Mike,
<div> The first question is a good one. Th=
e car was built for autocross by a guy in Indiana who knew his stuff. Howeve=
r, I bought it from a guy who had bought it to run PIB, but knew nothing abo=
ut race engines. He had run it lean and holed #4. He told
me he had not changed anything, but that is turning out not to be the case.=
(I suspect it holed the piston because I found he had fitted gros jets with=
the float level way too low). </div>
<div> I rebuilt it to same mechanical spec. It ra=
n great but a little lean on the AAU needles for road course, so I=E2=80=99m=
now on AAA. It still runs great, unless it doesn=E2=80=99t =F0=9F=98=81.</d=
iv>
<div> The car has had this issue since I built it=
. At first I thought the obvious - float heights, needle/seat, regulator pre=
ssure etc etc but while it always runs great I have this issues after a few =E2=
=80=9Claps=E2=80=9D.</div>
<div> 2) The car had a Summit racing 3136 pump wh=
ich has around 90GPH and an internal blow off at 7PSI, my regulator is at 4 P=
SI. Today I had taken the pump apart and checked it but all looked OK. I fit=
ted a cheap solenoid pump in its place. Issue still
there.</div>
<div>I had checked both the Summit and now the solenoid pump for flow, there=
is plenty. </div>
<div> As I noted the float bowls are full when it quits r=
unning.</div>
<div> 3) Great point - could be what I have. I know the fuel le=
vel in the jets is fine when not running, but a poor flow from bowl to jet w=
ould change that when running. My O2 is in the collector, so I can=E2=80=99t=
be sure if it=E2=80=99s both carbs or just one. All 4
plugs look very similar, but that is possible as this =E2=80=9Clean=E2=80=9D=
condition is only for a few cycles before it stops - not enough to color th=
e plug. Will check when I can ( unfortunately a busy weekend coming up as I r=
ace sailboats too ). I=E2=80=99ve been thinking it
is heat related, but it could just as easily be time. When I tried to run a=
utocross it started to play up after 10 or so seconds of full throttle (whic=
h I can=E2=80=99t do in my yard). On autocross it would pull like crazy, the=
n go very flat, and then come back on,
repeat. Your idea would do just that ! </div>
<div> 4) always worth a check, but it would have to be somethin=
g that shows up only when hot. </div>
<div> 5) yes, compression good. Between 220 and 225 for all, me=
asured on crank with throttles open.</div>

<div dir=3D"ltr">Hi Andrew, a couple of things to check.
<div>1st, is this a new problem? if so, what did you touch last?</div>
<div><br>
</div>
<div>2d Verify fuel flow, not just pressure i.e Gallons per hour? Disco=
nnect the fuel line at the carbs, and stick it into a 1 quart or one gallon c=
lean/clear bottle/jug. Turn the fuel pump on and time how long it takes to f=
ill (1 Qt/ 1Gal whatever size container
you're using). If you're getting more than 20 gallons per hour, the f=
low is OK. Set the bottle aside and let it settle out, look for particles, r=
ubber, fuel cell foam, dirt. If so, see where that's coming from. For exampl=
e, old fuel cell foam will break down
and clog the intake. When the pump turns off, the fuel in the lines drops b=
ack flushing the intake clear until next time. Fuel filter clean? Fuel press=
ure reg OK? Not just holding pressure (I run 3.5 on my HS4s) but actually se=
nding fuel down the line? The
gallons per hour test will indicate if you need to look into any of these a=
reas, if you're gelling enough fuel, more down the list for now.</div>
<div>link to flow and fuel requirements chart <a href=3D"https://histor=

/div>
<div><br>
</div>
<div>3. A problem I had with an identical set up, was rubber hose break=
ing down and settling into the little box shaped well in the carb bowl w=
here the line to the jet connects. It's happened to me twice now, last t=
ime was in June with fairly new hose feeding
the carbs. It restricted the flow to the jet, even though the bowl was full=
. At high load, not enough fuel could get past the blockage.</div>
<div>
<div><IMG_20240630_112925914.jpg></div>
</div>
<div><br>
</div>
<div>4. Vacuum leak- Is there a crack or loose bolt on the intake manifold? W=
ith the engine running, spray carb cleaner around the manifold to block, car=
bs to manifold. A change in engine RPM means something was drawn in through a=
gap.<br>
</div>
<div><br>
</div>
<div>5. Compression check- Are all the cylinders within 5-10% of each other?=
</div>

Guys, <br>
My car ( 1300, 12.5:1 comp on Sunoco 110 r=
ace gas, dual HS4 ) is still giving me grief. I=E2=80=99ve chased all the th=
ings I can think of, but still same problem. It starts and runs great, but a=
fter a few laps of the yard ( 5-6, only 1000ft or so per up/down
lap, so quick accels then braking to turn ) it goes very lean ( I have O2 s=
ensor ) and stops. I=E2=80=99m running it without the hood for these test ru=
ns. It always stops at the entry to a turn.
<br>
I=E2=80=99ve been working on it a lot, so k=
now it has fuel pressure, and the float bowls are full of fuel. All plugs lo=
ok very similar. The needles (AAA) are the spring type, and the slides move f=
reely. I use ATF as fluid, but have tried 50 weight too.<br>
After a minute or so it will fire back up, but o=
nly run enough to get back to the shop before going lean again. If I pull ou=
t the choke it will run, but is unstable.
<br>
I have wrapped headers and a heat shield around t=
he carbs but they do still get hot.<br>
<br>
Any ideas ? Thinking to try some less volat=
ile fuel as it seems heat related and the Sunoco evaporates so fast !<br>
<br>
<br>
Thank you, <br>
