Yup, you Eff'd yourself. But all is not lost.

The little pointed wooden dowel that comes with the Moyer kit is a valuable item, I have used it many times. Now that you have a good seal with the needle and seat, I don't think you need to worry...

I suspect your exhaust may be the problem. Fix that, then if applying the choke keeps it from bogging down, you are running too lean. This could be from a lack of fuel flow, a common problem. Having...

Theo,
I think you are on the right track with suspecting a fuel clog. In my experience that is the usual problem with these engines. Drain your Racor to see if it has a lot of water in the bowl. If...

You have come to the right place. Sounds like a fuel issue, or an idle issue. I'm guessing idle, since it runs well enough at higher rpm. To the excellent advice above, I would add that you should...

100:1 ratio?
That makes me do the math. Usually, I put 2 oz. MMO per 5 gallons of gas. So, 20 gallons gas would need 8 oz. MMO. 5 gallons is 640 oz. 1% of 640 is 6.4 oz.
So, I am using around 30% of the maximum...

Today I checked compression. Results are: #1, 110. #2, 130. #3, 75. #4, 135.
The 75 reading is concerning, but it should not keep it from starting, and may solve itself as it warms up. Then I...
