I thought I would pass this along so others would not go through this......                        Even with 39 previous speedsters under my belt, I had an issue with a "no run fresh rebuild motor " that I could not resolve, I was stumped .  It would crank and sputter but not run, did a detailed diagnostic check  #1 TDC, valves opening correctly, 12v to coil. (10.75 v under cranking load) confirmed it was not a key switch issue, confirmed proper fuel flow, wires, plugs ...blah blah and still would not run.  The only thing IMHO left was internal i.e.. cam timing.   yanked the motor ( in just 24 minutes)   drove 2.5 hours this AM to the builder shop, we bolted it to a motor stand and it fired right off and idles ! ! !    

I had bought this speedster project with a chassis w/ trans already installed..               It had a bad chassis to trans ground strap connection that would allow the starter to crank but not properly ground the motor.   Beer time !

Alex!  Re-read his next-to-last sentence.....  It was a bad pan to tranny ground strap (so he says . . . . . He's probably just saying that to save face because he didn't actually connect the damn thing in the first place).  

Did he check the ground strap?

Next time, CHECK THE GROUND STRAP!

Regardless.....It's Beer Time!

(I bet that Carey checks his ground straps!)

This just in.

One of Alan's secret helpers found the build list on the floor of the Merklin Motor Works shop and if you look at item 7 you'll clearly see that Alan did not check off the all important Trans to Chassis Ground:

  1. Choose a Speedster X
  2. Choose an engine X
  3. Mount the engine X
  4. Check the axles and drivetrain X
  5. Pedal Assembly X
  6. Shifter  X
  7. Transmission to chassis ground _
  8. Fuel system X
  9. Brake system X
  10. Intake and exhaust system X
  11. Electrical system X
  12. Body work X
  13. Interior X
  14. Wheels and tires X

Glad you sorted it, Alan. And thanks, again, for sharing your foibles with us. It makes us all feel good since most of us would do something like what you did every damn time, with the exception that, in our cases, it would take us four days to decide to pull the engine, two more weekends to actually do it, etc. etc., and 48 posts on SOC before we determined that a little brass thingie was missing from the right side carb.

I grounded myself to my Ham Radio transmitter once when I was working on it - I think I was 15 years old at the time.  Went in one hand and out through the other.  600 volts DC at about an amp.  Knocked me out for 15 seconds or so and I've still got the scars on my hands from it.  Our family doctor looked at me later that day and proclaimed me to have "the heart of an OX!"  Been proving him right ever since.

Honestly, it's no wonder my mother had white hair........

In college, our frat rooms were pretty small, so we came up with all manner of methods for elevating beds. My roommate mounted his bed to the wall up high and mine was on the ground. His desk was under his bed.

These were steel beds and my roommate hung an old metal lamp from his mattress springs over his desk. My bed was pushed up against the radiator. Unbeknownst to us, that lamp had a ground fault.

That scenario existed for a long time until one day, one of our brothers came in to chat with us and grabbed my roommates bed frame and mine while standing there.

110V right across the heart. He was shook up, but unharmed :-)
