I have been reading posts on here for about 6 months. I am thinking if building a 28 Briggs vertical for a 12 hp sport stock class in my pulling club. Everybody says it can't be done. Our rules are as follows
Stock bore and stroke.
Stock valve sizes
Stock rod length
Stock or stock replacement piston
Aftermarket billet rod ok
Engine manufacturers stock carb up to 1"
Steel flywheel
Stock ignition
I was wondering if we could combine all the 28 flathead tips to one post. Things I am concerned about are...
What is the best carb?
How do you keep the oiling system with no governor?
Is the ohv piston a better choice and what has to be done to fit it?
If anyone can share any tips it would be a big help. Last and final question. Will it run with a 12 hp kohler?
Thanks in advance.
