I want to do a few mild mods to this engine, keeping it below 4000 RPM.
The bore, (now honed), is 3.380", (standard is 3.375")
Will a new standard piston and ring set be too loose... or should I just bore it out to
the .010 over size and get the matching piston and rings?
Should I go for the 18 HP cam, which is supposed to have a bit more duration?
I need new valves, followers and the seats ground anyway... should I stick with the
standard size, or go bigger, with a little chamber re-shaping and light porting?
And I will use a 3" intake extension under the carb.
(Any better carbs???)
I think all of the above mods, (combined), is enough, and will complement eachother.
Also, I want to go with a stator and 9-1/2" flywheel for ignition...
(with the ring gear, so I can put the newer starter on it too.)
I know I have to change the shroud, but my bearing plate looks like it'll fit the larger
flywheel... it has the half circle cut out for the starter gear...??
And then I'll mount this one on the B-10... I think... or my David Bradley walk-behind.
thanks in advance
