Hey guys buddy of mine has a built vtwin,billet wheel set full neg , really good honed block , stock pistons with new rings , arc rods, precision cheetah cam, 49 heads milled 110 , ec roller rockers, dual springs with stock push rods, , valves are set at .003, cam is installed straight up , yes it has the hi torque starter a good battery, when he goes to whirl it over it it keeps jamming up on the compression stroke , any ideas, need a bigger batter , weak starter , internal issues , anyone run into this before or have any further ideas? Thanks I’m sure it’s been covered before just covering all my bases , cheers
