    Timing oh hs40 with solid state ignition

    if I am correct the solid state engine might also have smaller valves. just depends on the year...etc. and if so the bowl opening/seat area will be smaller too. it doesn't take much to effect a engines performance over another one. just a bad responsive carb can kill it all.

    Grinding a Tecumseh Cam

    Yes,thats where you would have to come in with a rough stone first and then clean up the last .010-.020 with a finish stone so it's spot on and you have makesure all your pivot points are true and accurate. For example your door hinges will need to be up graded.

    Grinding a Tecumseh Cam

    maybe look into using a grinding wheel stone. for example the type that are use for grinding valves. they come in all different finishes. using a grinding wheel you could get a more accurate grind(spot on) with that belt your getting more inaccurate finish with it flopping around. also with a...

I personally would not trust the stock valve springs...

    Grinding a Tecumseh Cam

    little off on your rpm range for your dyno cams. the 245 is good to 6000+ and the 255 is 7000+ and the 356 is 9000+ (dyno cam spec's) I have use all three cams in well set up motors and I have found the 245 in my hs40 comes on strong at about 3500-3800 and go's easy up 7000+ 255 in a ohh motor...

    AM Hawg Ty with new torque converter and electronics test ride

    looks like a lot fun riding. I like to build another large baja bike with rear suspension again and run a 7inch 20 series comet(no overdrive) and also a larger rear sprocket with a good strong low end torque motor. get two or more guys together and road trip all day on the trails.

    AM Hawg Ty with new torque converter and electronics test ride

    what I like about them is the tread wraps around to the side. not like most tires don't do and the tire is round allowing to roll the bike hard into the corner and not dumping it. I think the smooth rocks would be the only bad spot?
