Working on this old B, went thru carb, mag, new plugs. Valve job, Rings, Push rod tubes etc. Really has a lot of compression, at least when your cranking. Finally starts and runs and idles fine. Have tried choking but will not pop with choke on< I just crack the throttle and after about 10 or 12 cranks it finally starts. Russ

John T is right, try 2 turns with choke on and then flip off, should start. Crack your throttle so that it is off the stop 1/4 in. good luck!

The problem with unstyled B is with no petcocks, you cant observe how much raw gas or vapor etc or anything similar to being observeable with petcocks. Most tractors, dependign on teh timing, condition of engine and mag etc all start a little different. Of course, with the hand crankers, the mag and its points condensor and especially trip spring all have to be RIGHT. If cold on my 38 B, I give it full choke for ONLY two piston compression pull overs max and then back it off to about 3/4 to 7/8 choke. If warm, she likes about 7/8 choke and if she dotn start firt pull, about half till she does. I prefer Autolite 3077 side wire electrode plugs. Check ur points for 0.015 setting and the initial static mag timing also. Slow timing can hinder hand starting but if to fast she kicks back which I hate. Ol John T Nordhoff

This may sound crazy but my grandpa showed me this trick on my 36' B. Bring your flywheel around until its at the point where you have to pull it through the compression stroke, but instead of pulling it through, open your choke all the way up, close throttle and turn your flywheel counterclock wise about 1 turn, you should hear it take a gulp of air and fuel, I do this twice, (three times when cold). Bring it back up on compression stroke, close choke, 1/2 throttle and crank it through. works every time for me,usually on first pull if not second. My grandpa said that every two banger has its own little "trick" to easy starting, hope you find yours.

Russ unless it is relly cool I found that my 38B starts easyer by not even using the choke. Dave
