Trouble starting hot -53 Pan

#1

Post by gilb » Fri May 08, 2015 8:46 pm

Just got my 53 FL back together, replaced neck on frame, painted, etc and installed a quickstart 2000. I start it cold and run for 20-40 minutes and it runs great. Problem is that I cannot start it again, when hot. I have first tried starting without touching anything, also wide open throttle, in case it is flooded, also choke like cold start, but nothing. I pull the plugs and do not smell any fuel and they do not look wet. I have tried starting fluid, no pop. I pull a plug out and watch it fire, every time just before TDC and again at about 90 degrees from there, not sure if that is right. Any suggestions? Thanks!

gilb,
What carb are you running?
S&S "E" ?
or
Linkert?

When you put it all together, did you bubble test the manifolds? Also, did you adjust the linkert as per the manual? Should be 5 turns out on the low speed and 2 out on the high speed as a default setting. This default setting is rich and will be a pain to start when hot or even warm. Does it idle ok when running? This would be a first tell sign if you have any intake leaks. Did you make sure the carb to manifold is flat? Phenolic spacer flat? I had a warped linkert in that area that was giving me fits.

First, it idles and runs perfect. On this disassembly, I never seperated the manifold from the heads, but had tested it for leaks before and I did have the carb to manifold, flat. I have put about 2500 miles since doing that. I adjusted the carb back then too and have not done anything since, but it was fine then. It did get a bit harder to start when I put hydraulic lifters in it, but now it won't start at all when hot.

Thanks

Gilb---Bubble-test it the right way/Sounds like a Leak,intake.If your firing up on 1-hot when cold--When shes hot Things move/Also I know if a hall/sensor gets hot/They act-up.Most electronics use Di-Electric grease under the sensor to aid in cooling,& moisture.Also correct wires & Coil are needed.Dont forget BATTERY!--Electronics are very hungry & need the correct voltage to work right.Just a few things to throw at you.I would Bubble-Test as RAN suggested earlier.-----Richie

gilb,

Did you replace your stock coil with a 3ohm coil at the same time when you installed the Quickstart 2000?

I did not replace the coil. I did an ohm check and have 2.8, which is suppose to be acceptable(actually had different readings on different meters, so could be less). Where do you find a 3 ohm coil, if that could make a difference?

Also on the intake check, can you check using propane around the connections? I have a snap-on product, using propane, that I use on cars to test that way. If you have a leak it will raise the idle.

Thanks to all for your input.

I wouldn't recommend using propane. Remove the carb, then attach regulated 15psi of air. I use a rubber stopper with a quick disconnect air nipple threaded in it that fits in the manifold. I worm clamp it to the manifold. Soapy water is what seems to be the consensus.
Spray all around the intake and the valve cover screws a cause you never know....

gilb,

Yes, 2.8 ohm is ok.

Mark--He replied that 2.8 is ok!--It will give you max. performance from that system//Any elect. sys. for that matter.If you look at his sitefir the Q-2000--He says anything from 3-ohm to 4.7-stock points coil.Is good to use.I bet the coil that you have is 3-ohm!--I mean 2.8 is close enuff!--I have 3-different meters & the Fluke is the best one--The craftsmen is 3-off & the Snap-on reads exactly as the Fluke.----Richie

Riche,

Yes, I did read he has the 2.8 ohm coil. I was only pointing out the Q-2000's requirements from the website.

And yes, I have a 3 ohm Dyna Coil I use for my Q-2000.
