Got Grandpa’s H Running Today!!! (Videos)

After getting the spark and fuel issues sorted out, I pulled my Grandpa’s ’52 H out of the garage today to see if it would start. I was amazed that the first time I pushed the starter button it popped and showed some life. At first it would only stay started when I had the starter motor going, but I got it going longer by playing with the choke some.

I didn’t get to drive it around because it didn’t want to stay running. To keep it going I had to be on the choke pretty much the whole time. It would start the best if I pulled the choke rod towards me, turned it over some, push the choke rod away from me and then it would start. It wanted to stay running at mid choke, but I couldn’t keep it in the magic spot for very long or if I adjusted the throttle it wanted to die. There is also a slight gas leak at the bottom of the carb. I didn’t notice it right away and can’t tell if it was coming from the drain plug or the adjust screw on the bottom of the bowl (IH carb).

Here are some links to videos.

This first video shows how I struggled to figure out how to keep it running at first (you have to love my daughter’s comment half way through…)

The second video is the first time I got it to run hold an rpm. It sounded good to my ears!! My kids were pretty excited too.

I throw this third video in because it is interesting. I only had the H backfire one time and it is in this video. It looks like a puff of exhaust came out of the manifold.

This last video just shows how it wants to die if I push the choke back in and how it comes back to life when I change the choke position.

Open the high speed mixture screw a half to a full turn or so. Running too lean at this point.

IMHO, you need to take the carburetor apart and try again. Leaking fuel, and the engine starving for fuel at the same time indicates some major blockage in one of the passages.

First of all congratulations!! I missed the leaking fuel part. After you open up the bottom mixture a half turn (counterclockwise) there is a nut under that screw. Hold the screw and try tightening that nut which squeezes the packing tighter against the screw.

Thanks, The Red!!!

One half turn out and tightening the packing did the trick. I got to take it for a little spin tonight!
