If you have an older motor / engine, it’s always a good idea to change the crank seals as part of your preventative maintenance. Air leaks can develop over time through the crank seals and can cause a lean condition and serious motor damage. Leaking crank seals can also cause many symptoms of bogging and stalling, leaving you thinking there is something wrong with the carbs or electrical. If you’re not sure of your motor’s history, we always recommend installing a fresh set of seals.
We also have the ThreeBond 1211 case sealant and complete gasket kits available. Multiple quantities available with a shipping discount already provided.
International shipping is also available on most of our items. We normally use USPS airmail and rarely have problems; however, we cannot accept responsibility for lost packages, hold-ups at customs, or any other unforeseen circumstances that can happen with international shipping.
