Scorpion won't start

Keith Ehrlichman /

Pulled an old Scorpion SC-2 out of the shed that hasn't been run in around 10 years and got it to run for a bit after dumping gas in it. Ran for about 30 seconds and then stopped and couldn't get it started again. Didn't think much of it since we planned to clean the tank and carb and was just happy that it still fired up. After cleaning the tank and carb and installing a new plug, we can't get it to even fire. Tried a couple new plugs and verified there is spark. Also tried starting fluid but nothing. We noticed we have to crank the pedals at a fairly high rate to get spark. Is this typical? Any ideas on what I should try next?

The first step :

Clean and scratch tighten every electrical connection .

Including clipping a 1/4" off the end of the HT wire at both ends , if possible .

Thanks for the reply. What is the HT wire and if wiring was an issue, wouldn't that cause it to not have spark?

HT : High Tension : Spark plug wire .

You said it ran for 30 seconds . Great .

You said it has spark . Most likely you tested outside the compression chamber .

It's very possible that there's not enough spark to do any good in the compression chamber . That's where cleaning and scratch tightening connections comes in .

Corrosion acts strangely sometimes . 10 years can create a lot of it .

Like I said : 'First step'

Eliminate the easiest first . Once you know the electrical is copacetic , move on .
