Frequently Asked Questions

Which jet size do I need?

Match the jet to your carburetor spec; the metering size is calibrated, so confirm against your original before ordering.

How do I know the jet is restricted?

Poor part-throttle running or a lean stumble in the secondary circuit points to a clogged or wrong jet. Pull and inspect it - do not drill it, as the metering size is calibrated.

Can I drill the jet to change the size?

No. The metering size is calibrated, so clean the passage and fit the correct jet rather than modifying it.
