motor missing at high rpm HELP!?!?!

[macojoe]

Well it could be the points??

When were the plugs changed last??

As for the gas the best thing would have been to drain the old then add the new.

If you know a little about motors you can kind of tell when it is gas and when it is electrical.

If plugs are ok and not fouled, this would be from points not opening. Check the coil also.

Being that it is fine when slow and breaks up at high speed I no think the gas.

But that said I be willing to bet you have a restriction in the gas line some where??

Are the vents clear?? Take air hose and blow all lines out including vents. Add new filter

Could be a weak fuel pump??

Check vaules on the fuel tank could be all gooped up from the old gas and getting stuck??

Add some Gumout to the gas and spray the Carb all down to make sure it is all clean.
